Back Cover LX and LT Low NOx A. S.M.E. Pool/Spa Heater Page 1 SECTION 1. General Information 1.1 Introduction This manual provides installation and operation instructions for the Laars LX and LT Low NOx A.S.M.E. certified pool and spa heaters. Read these installation and operation instructions completely before proceeding with the installation. Consult the Laars factory, or local factory representative, with any questions regarding this equipment. Certain sections of this manual are specific to either United States or Canadian installations, and are labeled as such. The Laars LX and LT Low NOx heaters get their electrical power from an external 115VAC or 230VAC source and provide a dual electronic thermo- stat control system for pool/spa combinations or preheat convenience. The Laars LX and LT°Low NOx heaters are specifically designed for heating freshwater swimming pools and spas, and with proper installation.and care, they will provide years of reliable service. Do not use the heater to maintain pool or spa water temperature below 70°F. Do not use it as a heating boileror general service water heater or to heat salt water. Consult your dealer for the appropriate Jandy products for these applications. 1.2 Consumer Information and Safety The Laars LX and LT Low NOx heaters are designed and manufactured to provide many years of safe and reliable service when installed, operated and maintained according to the information in this manual and the installation codes referred to in later sections. Throughout the manual safety warnings and cautions are identified by the "A" symbol. Be sure to read and comply with all of the warnings and cau- tions. 1.2.1 Spa/Hot Tub Safety Rules A WARNING The following "Safety Rules for Hot Tubs," recommended by the U.S. Consumer Product Safety Commission, should be observed when using the spa. A AVERTISSEMENT Les Reglements suivants pour Cuves Thermales, tel que recommandes par la Commission U.S. de S6curite des Produits pour les Consomrnateurs,devraieht 6tre, respectes lois de l'utilisaton du spay AWARNING The U.S. Consumer Product Safety Commission warns that elevated water temperature can be hazardous. Consult heater operation and installation instructions for water temperature guidelines before setting temperature. A AVERTISSEMENT La U.S. Consumer Product Safety Commission indique que,destemperatures de 1'eau elevees peuvent etre%dangereuses. Voir I& notice. d'installation et de fonctionnement,pour le reglage de la temperature.. 1. Spa or hot tub water temperature should never exceed 104°F (40°C). One hundred degrees Fahrenheit (100°F [38°C]) is considered safe for a.healthy adult. Special caution is recommended for young children. 2. The drinking of alcoholic beverages before or during spa or hot tub use can cause drowsiness which could lead to unconsciousness, and subsequently result in drowning.. 3. Pregnant women take note! Soaking in water above 102°F (38.5°C) can cause fetal damage during the -first three months of pregnancy (which could result in the birth of a brain-damaged or deformed child). If pregnant women are going to use a spa or hot tub, they should.make sure the water temperature is below 100°F (38°C) maximum. 4. The water temperature should always be checked with an accurate thermometer before entering a spa or hot tub. Temperature controls may vary by as much as IF' (I C°). 51. Persons with a medical history of heart disease, diabetes, circulatory or blood pressure problems should consult their physician before using a hot tub or spa. 6. Persons taking any medication which induces drowsiness (e.g., tranquilizers, antihistamines, or anticoagulants) should not use spas or hot tubs. 7. Prolonged immersion,in hot watercan induce hyperthermia. Hyperthermia occurs when the internal body temperature reaches. a level several degrees above the normal body temperature of 98.6°F (37C). Symptoms include dizziness, fainting, drowsiness, lethargy, and an increase in the internal body temperature. The effects ofhyperthermia include: Page 2 Andy, • Lack of awareness of impending hazard • Failure to perceive heat • Failure to recognize need to leave spa • Physical inability to leave.spa • Fetal damage in pregnant women • Unconsciousness, resulting in a danger of drowning 1.2.2 Swimming Pool Energy Saving Tips Water Pik Technologies offers the following recommendations,to help conserve fuel and -minimize the cost of operating your pool heater without sacrificing comfort. 2. 3. 4. 5 6. 7, 8. The American Red Cross recommends �a maxi- mum water temperature•of 78°F (25°C). Use an accurate pool thermometer. A difference of 4F° (2°C) , between 78917 and 82°F (26°C and'28°C), will use as much as 40%more gas. Carefully .monitor the water temperature of your pool in the summertime. You can reduce heater usage due to warmer air temperatures. Find the proper setting on the ,pool heater temperature control and use the locking:ring to discourage further adjustments. (LT only). Set the pump time clock to start the pump no earlier than 6:00 AM during the pool heating season. This is the time when nightly heat loss balances. If the pool is only going to be used on weekends, reduce the heater temperature control setting by 8 or 10 degrees during the week. Reset it to the 78°F (25°C) level a day or so before you plan to use the pool. During the winter or when on vacation for longer than a week, shut down the heater. by following the shutdown instructions found on the inside of the heater. Where possible, shelter the pool from prevailing winds with well -trimmed hedges or other land- scaping, cabanas, or fencing. Always use a pool cover when practical. Besides providing a valuable safety feature, a pool .cover will reduce heat loss, conserve chemicals, and reduce the load on filter systems. 1.3 Warranty The Laars LX and LT Low NOx Beaters are sold with a limited factory warranty. Details are. specified on the back cover of this manual. Make all warranty claims to an authorized Jandy representative or directly to the factory. Claims.must include the heater serial number and:model (this information can be found on the rating plate), installa- tion date, and name of the installer. Shipping costs are not included in the warrantycoverage. The warranty does NOT cover damage caused by improper assembly, installation, operation or field modification. Also, damage to the heat exchanger by corrosive water is NOT covered by the warranty. See Section 8.1 for maintaining proper pool water chemis- try- NOTE: hemis- tryNOTE: Keep this manual in a safe place for future reference when inspecting or servicing the heater. 1.4 Codes and Standards All Laars LX and LT Low-NOx pool and spa heaters are design certified by CSA (Canadian Stan- dards Association) as complying with the latest edition of the "Standard for Gas Fired Pool Heaters", ANSI Z21.56 in the USA and CAN -4.7 in Canada.

Water connections are provided on the right side of the heater but can be changed to the left side by reversal of the heat exchanger. It is best to handle these preparations before the heater is 'installed in its final location. See,Section 5.4 "Reversible Water Connections" ofthis manual for instructions. 2.3 Location Requirements 2.3.1 Introduction A CAUTION When pool equipment is located below the pool surface, a leak from any component can cause large scale water loss or flooding. Water Pik Technologies cannot be responsible for such water loss or flooding or resulting damage. A ATTENTION Lorsque I'equipement dune piscine est situe sous la surface de Peau, une fuite provenant.de n'importe Opel element peut causer une perter d'eau. importante ou une inondation. WaterPik, Technologies n'est: pas responsable des pertes .d'eau, des inondations ou des avaries causees 0arune installation ou un entretien inadequat. The Laars LX and LT Low NOx heaters maybe installed indoors or outdoors as outlined in later sec- tions. Location of the heater below or above the pool water level affects operation of its water pressure switch. See sections on water piping and heater start- up for more information about this. Avoid placing the heater in locations where it can cause damage by water or condensate leakage. If this is not possible, provide a suitable drain pan to catch and divert any leakage. The pan must not restrict the air flow around the heater. All criteria given:in the following sections reflect minimum clearances.as-stated in the national stan- dards. However, each installation must also be evalu- ated, taking into'account the prevailing local conditions such as wind speed and direction, proximity and height ofwalls that may block ventilation, and proximity to publicaccess areas. 2.3.2 Clearances The heater must be placed to provide clearances on all sides for maintenance and inspection. There must also be minimum distances maintained from combustible surfaces (see Table 2).. At least 18" (457mm) access must be available in front of the heater for burner removal and access to the igniter. If the heater is to be installed in a garage, or similar structure, all burners.and burner ignition devices must have a minimum 18" (457mm) clearance above the floor. Page6 ,dy Table 2.

Noncombustible flooring is defined. as flooring material and surface finish not capable of being ignited and burning and with no combustible materials against the underside. Acceptable materials are those consisting entirely of a combination of steel, iron, brick, tile, concrete, slate, glass or plaster. Do not install the heater directly on a combustible wood or carpet floor without placing a noncombustible platform between the floor and the heater. The heater can be installed on a combustible floor if a noncombustible base assembly, available from Jandy, is used. See the heater rating plate or the Parts List (Section 11) of this manual for the appropri- ate base part number. Heaters must never be installed directly on carpeting. As an alternative to the Jandy noncombustible base plate, in the United States; the National Fuel Gas Code, and in Canada, the Gas Installation Codes CAN/ CSA -13149.1, allow a heater to be placed on a com- bustible surface when there is a platform under the heater made of hollow masonry no less than 4 inches (102 millimeters [mm]) thick, covered with sheet metal at least 24 gauge thick and extending beyond the full width and depth of the heater by at least 6 inches (153 mm) in all directions. The masonry must be laid with ends unsealed, and joints matched to provide free circulation of air from side to side through the masonry Note: Clearances listed in Table.2 are manufacturer's tested values. These are given as minimum values. Where local and national codes apply, and values are different than those listed in Table 2, use the greater value to ensure safe operation. • Refers to! opposite piping. ** A closet with no door Notes: W, 1. Blocks must provide a solid base and be braced so they cannot slip out of place. 2. Air openings in blocks must be arranged to provide unrestricted opening through entire width or length of base. 3. Sheet metal must be at least 24 ga. and extend 6" beyond the heater jacket on all sides. Figure 2. (see Figure 2). If the heater is installed in a carpeted alcove, the entire floor of the alcove must be covered by a -noncombustible panel. 2.3.4 Outdoor Installation The LX or LT Low NOx heaters can be installed in the outdoor configuration as received from the factory. Locate the heater in an open, unroofed area. Do not install the heater under a deck. Do not locate the heater below or adjacent to any doors, glass openings, louvers, grills, etc., which connect in any way with an inhabited area of a building, even though the access LX and LT Low NOx A.S.M.E. Pool/Spa Heater Page 7 might be through another structure (e.g.,.a,garage or utility room). In the United States there must be a minimum of four (4) feet (1.22: m) horizontally and four (4) feet (1.22 m) vertically between the heater exhaust point and any door, glass opening, or gravity inlet to a building. In Canada, the heater must be installed so that the exhaust point of the heater is at least ten (.10) feet (3.0 m) from any building opening (see Figure 3). ®WARNING United States Do not install the heater with the top of the vent assembly within 4 feet (1.22 m) horizontally and 4 feet (1.22 m) vertically of any opening into a building.

La parties sous1a saillie doit.etre ouverte sur 3 cotes. If the heater is installed close to a structure, protect it from rain water runoff with rain gutters on the roof or other measures. Do not locate the heater near irrigation sprinkler systems that could -spray water on it. Water from sprinklers may cause. damage to controls and electronic components. Avoid locations where wind deflection off nearby structures might cause downdraft conditions.. Where downdraft conditions exist, locate the heater at least 3 feet (0.91 m) from vertical surfaces (e.g., nearby buildings and walls). 2.3.5 Indoor and Outdoor Shelter Installations An outdoor shelter (Canada only) is an unoccu- pied enclosure which does. not communicate directly with occupied areas. All indoor installations and outdoor shelter installations require the addition of a factory approved vent collar. The vent collar must be installedwithout modification and in accordance with the instructions provided by the manufacturer.

These codes. standards and Water Pik Technolo- gies require that the heater be properly vented as outlined in thismanual. Proper ventilation:ofexhaust and combustion air are essential for the safe and efficient operation of the heater (See Section 3). 2.3.5.1 Converting_ the Grill to a Vent Collar If the LX or LT Low NOx is to be installed either indoors or in an outdoor shelter, its exhaust discharge grill must be converted to a,collar for vent pipe connection. The necessary vent collar, gasket and screws can be ordered as parts kit R0331403 for model 250 or R0331405 for model 400 (see parts list in Section l 1 of this manual). The conversioncan be done quitesimply as follows: 1. .z Remove the vent exhaust:gri.11 by removing the four screws which retain it. The grill and the screws may be discarded (See Figure 4). Page 8 andy. 2. Replace the grill with the vent collar. Place the vent.collar and gasket over the hole and fasten it in place with the 4 screws provided. Be sure that all components are properly aligned (See Figure 5).. 3. Install the vent pipe on the indoor vent,collar. The collar will accommodate vent piping ofnominal 7" or 9" diameter (see Table 4), depending upon the model of your heater (See Figure 6). See vent installation section for important information on selecting properpipe size: Flgure4. Removal of Outdoor Exhaust Grill Figure & Vent Collar Assembly for Indoor and Outdoor Shelter Installation Figure 6. Vent Pipe,lnstallation SECTION 3. Venting 3.1 Combustion Air Supply The heater location must provide sufficient air supply for proper combustion and ventilation of the surrounding area as outlined in the latest edition of ANSI standard Z223.1 or in Canada, CAN/CSA- B149.1, and any local codes that may be applicable. In general, these requirements specify that the .room in which a heater is installed should be provided with two permanent air supply openings; one within 12 inches(305mm) of the ceiling, the other within 12 inches (305mm) ofthe floor. All indoor installations must have openings to outside air for combustion, ventilation, and dilution of flue gases from inside the building (see Figure 7 and Table.3). WaterPik Tech- nologies does not recommend indoor installations that do not provide combustion air from outside the build- ing. Table 3.

Forspecial conditions, refer to NFPA54 NSI Z223.1. In Canada refer,to the National Standard CAN/ CSA -B149.1 which differs from this table. Note: If using screens and/or metal louvers, compensate by adding 50% additional area to each opening If using wood louvers each ropening must be at least four times the area indicated, in the table above. All outdoor shelter installations (Canada,only) must have uninterrupted openings to outside air for combustion and ventilation. The installation must be in accordance withthe latest edition of CAN/CSA B 149.1. Water Pik Technologies does not recommend outdoor shelter installations that depend on internal air for.combustion. Combustion air should be ducted to the heater from outside the structure. Outside Air Supply When combustion air is supplied directly through an outside wall, each opening should have a minimum free area of one square inch per 4,000 BTU/h (1.2kW) input of the total input rating of all appliances in the enclosed area.. If air is provided through horizontal ducts, each opening and duct must provide one square inch of flow area for each 2000 BTU/h (0.6 kW). These requirements are summarized in Table 3. Note that the areas specified are net free areas and should be increased when the openings are covered by screens,Iouvers, grills or other protective covers (see Figure 7 and Table 3 notes).

Exhaust Fans or Vents: Any equipment which exhausts air from the room where theheater is installed can deplete the combustion:airsupply or reverse the natural draft action of the venting system. This could ,cause flue products to accumulate in the room. Additional air must be supplied to compensate ,for such exhaust. The.information in Table 3 i not applicable in installations where exhaust fans or blowers of any type are used. Such installations must be designed by qualifed'engineers. The heater must be completely. isolated and protected from any source .of corrosive chemical fumes,such as those emitted by trichlorethylene, perchloroethylene, chlorine, etc. A WARNING Do not store any chemicals, cleaners, or other corrosive material' near combustion air openings or in the room. Avoid locating appliance vents in the vicinity of combustion air openings. Failure to prevent corrosive materials from mixing with combustion air can result in reduced heater life and unsafe heater operation. `A .AVERTISSEMENT Ne paS entreposerni.utiliser d'essence ril 4autres vapeurs: ou liquides Inflammables a proximife de cet a- ppareil ou de tout autre appareil. . 3.2 Exhaust Venting When converted to indoor and outdoor shelter venting configuration, the LX and LT Low NOx heaters have a vent collar fitting. The diameter of the vent collar and, thus, the minimum diameter of the vent pipe to be used is determined by the model of heater installed.. The only correct procedure for vent pipe sizing is to do so in accordance with Table 4 and the applicable installation codeas stated in the following "Danger" warning. A WARNING Vent pipe diametermust be as required by'the 'National fuel Gas Code Z223.1 or the Canadian Installation Codes for Gas Appliances CAN/ CSA -8149.1. Undersize pipe can result in ,inadequate venting and oversize pipe can result in vent condensation. In either case the result can be release of combustion products to the indoors. This can cause serious injury or death by carbon,monoxide poisoning or asphyxiation.

They are intended for stan- dard vertical venting;per tables.provided..in most local codes for Category l Fan -Assisted appliances. If the local code does not include. such tables, refer to the National Fuel Gas Code, Z223.1 or the Canadian Installation Codes for Gas. Appliances CAN/CSA- B149.1. Note that the tables for fan -assisted appli- ances include both maximum and minimum vent loading figures. The primary purpose of the maximum. ratings are to assure that the vent operates with negative pressure throughout its length. The minimum ratings are to assure that vent gases don't cool too much and thereby assure that condensation doesn't occur. 3.3.1 Outdoor Installations For outdoor installations, exhaust venting consid- erations will determine the placement of the heater (See Section 2.3.4). If the heater cannot be placed so as to meet the requirements stated in Section 2.3.4, a vent collar may be added to the heater to move the exhaust vent opening to a position that complies with. the requirements. In all cases, vent collars must be of the same diameter as the exhaust outlet of the heater. Approved vent collars may be obtained through your Jandy distributor. 3.3.2 Indoor and Outdoor Shelter Installations All indoor installations and outdoor shelter installations require the addition of a factory approved vent collar. The vent collar must be installed without modification. All ventinstallationsmust be made in accordance with all local, state or provincial codes and with: I . Chapter 10, " Venting of. Equipment" of the national Fuel Gas Code, ANSI 223.1 latest edition, or the applicable provisions ofthe local buildingcodes: , 2. In Canada, CAN/CSA B149.1. Avoid terminating heater vents near air condi- tioning or air supply fans. The fans. can pick up exhaust flue products from the heater and return them insidethe building, creating a possible health hazard. Do not locate the vent terminal where flue products could strike againstbuilding materials and cause degradation. Vent opening should be well away from trees or other obstructions that would prevent free air flow to and from vent terminal. Do not terminate the vent under decks, stairways, or car ports. Be sure to support all venting so that connections will not separate and so that the weight of the vent pipe does not rest on the heater vent collar.. All connections should be made with rustproof sheet metal screws. Do not weld or fasten the vent pipe to the heater vent collar. The vent collar and heater top must be easily removable for normal heater service and inspection. The vent collar outlet is to be connected to an unobstructed vent pipe of the same diameter, terminat- ing outside the building. The vent must terminate at least two (2) feet (0.6 m) above the highest point of the roof or other object that is within ten (10) feet (3.0 m) of the vent termination. The vent pipe must have a listed vent cap which allows a full equivalent opening for flue products (see Figure 7). Type `B" double wall or equivalent vent pipe is recommended. However, single wall metal vent pipe may be used as specified in the latest edition of the National Fuel Gas Code ANSI Z 223.1 or in Canada CAN/CSA-B]49.1. IMPORTANT NOTE: Do not use sheet metal screws at the snap lock joints of Type B gas vents. When venting multiple appliances through one common duct, each appliance must. have it's own vent temperature limit switch. All vent limit switches must be wired in series so as to prevent any appliance from firing in the event of a blocked vent. Refer to ANSI 2223.1 or, in Canada, to CAN/CSA B149.1 for more informationon multiple venting. SECTION 4.

Check the gas supply to be sure that it is the same as the gas indicated on the heater's rating plate. Laars LX and LT Low NOx heaters; as shipped from the factory, are certified to operate within the altitude range indicated on the "rating plate. If a field conversion to a different altitude range should be necessary, manifold kits are available for changing the altitude range of the heater. See Table 1 on page 4 of this manual to. .determine the correct altitude designation for your heater. Refer to Section 1.1 "Parts List" to order the correct parunumber of the manifold kit needed. When changing the altitude range of the heater, be sure to fill out the altitude conversion label, included in the kit. Apply the label on the inner panel of the heater, next to the original rating plate. A CAUTION Permanent damage to the gas valve will occur if the following procedures are not followed. A ATTENTION Vous endommagerez la soupape de gaz si. wousne respectez pas. les procedures suivantes. Page 11 3. Use the figures in Table 5 to size the gas inlet piping from the gas meter to the heater. Check all local codes for compliance before installing the heater. 4. Install a sediment trap (drip leg) ahead of the gas controls (see Figure 8). Fit the trap with a threaded cap which can be removed for cleaning. 5. Install a manual gas shutoff valve for service and safety. Do not use a restrictive gas cock. DO NOT USE FLEXIBLE GAS PIPING, it will restrict the gas flow to the heater. 6. Disconnect the heater and its individual shutoff valve from the gas supply system during pressure testing of the system at pressures higher than 1/2 pounds per square inch (psi) (3.45 kilopascals [kPa]). If the test pressure is equal to or less than 1/2 psi (3.45 kPa), close the manual shutoff valve on the heater during the piping pressure test. Table 5.

To connect the gas supply line to theheater's gas valve, make sure the steel elbow (supplied with the manifold) is screwed into the inlet side of the gas valve. The heater is designed so that the gas supply line may enter through either side of the heater. Hand tighten the elbow until the desired orientation is achieved. A CAUTION Do not overtighten the elbow. Over tightening will crack the gas valve. Do not use teflon tape to wrap the elbow threads. A ATTENTION Ne serrez pas trop le coude.

If the gas supply pressure is less than required, check for undersized pipe between the meter and the heater, a restrictive fitting, or an undersized gas meter. Gas supply pressures to the heater, when it is operating, are listed in Table 6. A CAUTION Manifold gas pressure for the LX and LT Low NOx natural gas heaters should be at 3" WC. Propane heaters should be set to 9" WC. A ATTENTION La pression du collecteur de pression pour les systemes de chauffage au gaz;naturel devrait etre de 3" WC. Pour les sytemes de chauffage. au_gaz propane devrait etre de'9WC. The, manifold pressure may be checked by connectinga manometerto the pressure port on the outlet side of the valve. The pressure will be zero when the heater is not running. When the heater is operating the manifold gas pressure should be 3.0" WC for natural gas heaters and 9.0" WC for LP gas heaters. To adjust the manifold gas pressure, first remove the slotted cap next to the inlet pressure port on the inlet side of the gas valve. Under the slotted cap is a slotted plastic screw which increases the manifold pressure when turned clockwise and de- creases the manifold pressure when turned counter- clockwise. After measurements, and adjustments if necessary, have been made, make sure to replace the 1/8" NPT gas valve plugs;on the inlet and manifold pressure ports, and the cap on the manifold pressure adjustment screw. WARNING Failure to replace the plugs and caps on the gas valve may cause a fire or explosion resulting in property damage, personal injury or death. A ATTENTION A defaut de remplacer les. bouchons et capuchons sur la valve a gaz pourrait en resulter un incendie ou une explosion provoquant des dommages materiels, des lesions corporelles ou mgme la amort. With the heater firing, the pressure must be within the range shown in Table 6. Also check the pressure with theheater off. 4.3 Special Precautions for LP Gas LP Gas is heavier than air and can therefore morereadily collect or "pool" in enclosed areas if provision for proper ventilation is not made.

However, if such an installation is required be sure to pay special attention to proper ventilation for LP gas. Locate heaters a safe distance from LP gas cylinders and filling equipment. Consult the National Fuel Gas Code (NFPA 54 / ANSI Z223.1, latest edition), the Natural Gas Installation Code in Canada (CAN/CSA B 149. I, latest edition), and any other local codes and fire protection authori- ties about;specific installation restrictions in your area. SECTION 5. Water Connections 5:1 Water Piping Figure.9 illustrates typical pipingfor pool equip- ment in pool/spa combination pools. With its electronic control, the LX and LT Low NOx heaters are particu- larly suited for this type of pool installation. For normalinstallations, do not install a shutoff valve or any kind of variable restriction in the water piping between the heater outlet and the pool/spa. In special installations where a shut=off valve, diverter valve or other variable restriction is required in the plumbing between the heater outlet and the pool, Water Pik Technologies recommends the installation of a pressure relief valveon the heater (see Section 5.6). Arrangement of pool system components other than as illustrated in these diagrams can affect the operation of the heater's water pressure switch. Location of the heater above or below the pool water surface can also affect operation of the switch. In general, the pressure switch can be adjusted to accommodate .this effect if the heater water connec- tions are no more than six feet below the pool water surface and no more than 15 feet above it. See instructions for pressure switch adjustment (Section. 7.5) for more information about this. Note that when pool equipment is located below the pool surface a leak can result in large scale water loss or flooding. Water Pik Technologies cannot be responsible for such water loss or flooding or the damage caused by either occurrence. For special installations such as water connec- tions below the water level of the pool, or for other questions contact the Jandy Technical Service department at (707) 776-8200 ext,260. 5.2 Check Valve Installation The heater must be protected from back - siphoning of water, which can result in dry starts. If there is any chance of back -siphoning, provide a check valve between the pool and the filter pump inlet. When an automatic chemical feeder is installed inthe plumbing, it must be installed downstream of the heater (see Section 5.7). A check valve must be installed between the heater and the chemical feeder to, prevent back -siphoning of chemically saturated water into the heater where it will damage the components. 9 -WAY CHANGEOVER / VALVE SKIMMER CHEMICAL FEEDER MAIN POOL RETURN CHECK VALVE RECOMMENDED WHEN CHEMICAL / FEEDERINSTALLED BALANCING i./ �iHEATER VALVES' FROM SKIMMER AND DRAIN SPA MAIN SWAY CHECK DRAINDRAIN CHANGEOVER VALVE VALVE FILTER PUMP MANUAL BY-PASS MANUAL BYPASS DETAIL MANUAL BV -PASS IS USED WHEN FILTRATION RATE EXCEEDS 125 GALLONS PER MINUTE Figure 9.

See instructions for pressure switch adjustment (Section. 7.5) for more information about this. Note that when pool equipment is located below the pool surface a leak can result in large scale water loss or flooding. Water Pik Technologies cannot be responsible for such water loss or flooding or the damage caused by either occurrence. For special installations such as water connec- tions below the water level of the pool, or for other questions contact the Jandy Technical Service department at (707) 776-8200 ext,260. 5.2 Check Valve Installation The heater must be protected from back - siphoning of water, which can result in dry starts. If there is any chance of back -siphoning, provide a check valve between the pool and the filter pump inlet. When an automatic chemical feeder is installed inthe plumbing, it must be installed downstream of the heater (see Section 5.7). A check valve must be installed between the heater and the chemical feeder to, prevent back -siphoning of chemically saturated water into the heater where it will damage the components. PN9e,4 _ andy. 5.3 Automatic Flow. Control Valve The inlet/outlet header of the.LX and, LT Low NOx heater comes equipped with an automatic flow control valve. The automatic flow control valve maintains the proper- flow through the heater at rates up to approximately'] 25 Gallons Per Minute (GPM) (475 liters per minute [LPM]). If the filter system flow rate is higher than approximately 125 GPM .(475 LPM), install a manual bypass valve (see Figure 9), then perform a temperature rise test (see Section 7.6) and adjusttheflow using the bypass valve until the proper temperature rise is obtained. 5.4 Reversible Water Connections The LX and LT Low NOx heaters are shipped with water connections on the right side, but they can be modified in the field to provide left -side water connections. This procedure involves removing the heat exchanger and reinstalling it with the ilet/outlet header on the left. side of the heater. Some of the heaterwiring and control components must be relo- cated, so this procedure must be done only by a trained service technician. Heat exchanger reversals are generally done before the installation of power and water to the heater. If you need to reverse the heat exchanger on a previously installed heater be sure that all electrical power, the gas. supply and water supply have been turned off before starting -the procedure. These as Figure 11. Water Connections Reversed instructions have been written to include the steps needed when reversing the water connections on an existing installation. If you are reversing the heat exchanger on a new installation, some steps will be ignored. Water connection reversal is illustrated in Figures 10 and 11. Proceed as follows: I . For an existing installation, drain the heater by removing the drain plug on the inlet/outlet header and the two drain plugs on the return header. 2. Remove the heater front panel (door). 3.

Be careful not to pinch any wires. Replace the two screws on the bottom flange to hold the cover in place. 47. Replace the front panel (door). 5.5 Connections at Heater The heater has 2" NPT universal header cou- plings.. You can connect threaded 2" NPT iron pipe or unthreaded. 2" copper pipe without an adapter (see Figure 14). Unthreaded 1 1/2" iron or copper pipe may be used with special seals available from your Jandy distributor. However, by installing the appropriate pipe adapters, other sizes may also be used. Plastic piping (PVC Schedule 40) can be con- nected to the heater if local codes allow it, by using the CPVC nipples included with your heater. To install plastic piping (see Figure 15): Remove CPVC nipples from plastic bag. 2. Screw CPVC nipples into metal flange until tight, using Teflon, tape on plastic threads. Figure 14.

Follow the manufacturer's instructions,provided with the primer and glue for preparation procedures and curing times. 5.6 Pressure Relief Valve A pressure relief valve (PRV) is recommended in all installations, and is mandatory in any installation in which the water flow can be shut off between the heater outlet and the pool/spa. A pressure relief valve is not supplied with the Laars LX and LT Low NOx heaters. However, it is recommended that a pressure relief valve be installed and may even be required by local codes. Be sure to check any applicable installation codes in your area to determine whether a pressure relief valve is required. The pressure rating of the valve should be at or below the lowest working pressure of any component in the_ system. Any pressure relief valve installed must comply with provisions ofthe standard described in ANSI Z21.22 for the United Sates of CAN] -4.4 in Canada. Follow these steps to install a pressure relief valve. Remove the 3/4 inch (19 mm) brass plug located on the top of the inlet/outlet header (see Figure 16). Install the pressure relief valve in the threaded hole from which the plug was removed. Be sure that the exhaust port of the PRV is plumbed so that any hot water is directed safely away from any public areas and away from any area occupied during servicing. Page 18 ,,�ndy Figure 16. PRV Installation and Thermometer Location for Temperature Rise Test 5.7 Auxiliary Components, Chlorinators, Ozone Generators, and Sanitizing Chemicals The LX and LT Low NOx heaters are manufac- tured with materials that are not compatible with high concentrations of ozone, chlorine, bromine, or other sanitizing chemicals. Heater damage caused by excessive chemicals or improper ozonization is not covered by the Water Pik Technologies warranty. Be sure to adhere to the following: • When ozone is injected upstream of the heater, install an off -gas mixing chamber, or an ozone bypass system between the heater and the ozone injector to prevent ozone and air from entering the heater. • When chemical feeders are used, plumb the feeder downstream of the heater and install an in-line check valve between the heater and the feeder (a minimum of 18" is required between the heater and the check valve). • Wire any electrical chemical feeder so that it cannot operate unless the filter pump is running.. If the feeder has an independent clock control, synchronize it with the filter clock. • Never deposit chemicals directly in the pool skimmer. SECTION 6. Electrical A WARNING ELECTRICAL SHOCK HAZARD.

Field Wiring Connections 6.2.1 Converting the Heater for a 115V Power Source To convert the Laars LX and LT Low NOx heaters to 115 Volt, 60 Hz AC requires reversal of the voltage selector board on the power distribution board. The following procedure should be performed before the heater is connected to a power source: Identify the power distribution board on the heater. It is located to the left of the fan intake on the raceway (see Figure 19). 2. Cut the plastic wire tieaat is holding the voltage selector board in place and discard the wire tie. Unplug the voltage selector board from the receptacle (see Figure 20). 3. Rotate the voltage selector board 1.80° and reinsert it into the receptacle so that the hole in the board is not visible. Be sure that the board is securely seated in the receptacle.. Figure 19. Location Of Power Distribution Board POWER z ice-' DISTRIBUTION BOARD WIRETIE VOLTAGE c� SELECTOR f iy 1 BOARD Figure 20.

A ATTENTION L'appareii .de chauffage: dolt etre connecte a une grille demise a.la terve par un fil de,cuivre- d'un diametre de calibre minimal 8. The. National Electrical Code and most other codes require that all metallic components of a pool structure, including reinforcing steel, metal fittings and above ground equipment be bonded together with a solid copper conductor not smaller than a number 8 wire. The heater-, along with pumps and other such equipment must be connected to this bonding grid. A special labeledbonding lug is provided on the right side of the heater`to accommodate this requirement. LX and LT Low NOx A.S.M.E. Pool/Spa Heater 6.4 Auxiliary Time Clock Wiring Electrical wiring must be in accordance with the latest edition of the National.Electric Code (NEC), ANSI/National Fire Protection Association (NFPA) 70, unless local code requirements,indicate otherwise. If you install a time clock to control the filter pump operation, it is recommended that the time clock have its own low voltage (Fireman's) switch to turn off the heater before turning off the pump. The switch should shut off the heater about 5 minutes before the filter pump shuts off. This will allow for a more efficient.operation by removing any residual heat contained in the heat exchanger back to the pool. To install a time clock auxiliary switch into the heater circuit, follow these instructions (see Figure 21): Remove heater door. Remove the two screws securing the raceway cover. They are located on the bottom flange of the cover at the corners. Slide the raceway cover down to expose the raceway. 4. Remove the factory installed jumper wire and tag from the terminal strip (see Figure 2 ). Connect the low voltage wires from the time clock auxiliary switch to the two terminals. Use American Wire Gage (AWG) No. 14 gauge stranded copper wire with a temperature rating of 221 °F (105°C) or greater (see Figure 22).

Typical Time Clock Wiring Page 21 If your time clock simply interrupts the high voltage power supply or has a high voltage output, do not connect the power supply of the heater to the output side. of the clock. Doing so will. prevent the blower from purging the residual heat from the heater when the heater turns off. This situation will damage the heater. The blower must be allowed to run for 45 seconds after the heater shuts off. 6.5 Remote Operation The Laars LX Low NOx pool/spa heater con- trols can be wired for remote operation. All Jandy AquaLink RS Control Systems will permit the heater to be operated by remote control. If you are setting up a new pool or spa system, call your local Jandy distributor or the Customer Service Department for information on the correct RS Control System to meet your needs. To maintain full functionality of an existing RS Control System when connecting to a Laars LX Low NOx heater, first determine the revision level the programmed chip in the RS Control System's Power Center Board. To check the revision level of the chip, press and hold the reset button on the side of the indoor control panel for 10 seconds then -release it. A number will appearon the display for approximately 5 seconds. This first number can be ignored. After the first number.disappears, a second number will appear in the display window. It will consist of digits fol- lowed by a revision level ("#### REV _"). If the revision level displayed here is at "I" or higher it will accommodate a Laars LX Low NOx heater without any modification. If the chip is at a revision "H" or lower the chip will have to be replaced with a newer version, or to install the control without modification see information later in this section. An alternate method for determining the revision level of the programmed chip in your RS control, is described in steps 14 below. An updated chip can be obtained through Jandy by ordering the PPD Kit. Instructions for changing the chip are in the kit. Do not connect more than two wires to any of the terminals in the RS Control System when connect- ing peripheral devices. If connecting the LX Low NOx heater to the RS Control System creates this situation, then a Multiplexing PCB kit must be used. Call your distributor or Water Pik Technologies to order the kit. To connect the Laars LX Low NOx to your RS control system, follow the steps listed below (See Fig. 23). 1: Turnoff the power to both the heater and the RS control. 2. Open the RS Power Center enclosure and remove the front dead panel. Page22 _ 4ndy Figure 23. Wiring a Laam LX Low-NOx to a Jandy RS Remote [NOTE! Only a revision "I", or higher, program hip in the RS system will support the LX Low Ox heater interface. 3. Remove the two screws holding the bezel in place. Turn the bezel over to view the circuit board on the back. 4. Locate the programmed chip on the Power Center Board (the larger square chip in the lower right corner of the circuit board). In the center of the chip is the revision letter. Ifthe.revision letter is "I" or higher go to step 5. If the revision level is "H" or lower, replace the chip. Directions for removal and installation of the chip are provided in the new PPD Kit. NOTE: If ordering a new programmed chip, be sure to order the part number printed on the chip currently in your RS control. Use 22 gauge 4 -conductor wire (Jandy part # 4278) to run between the heater and the RS control, and match the wire color order.. 6. The wires coming from the LX Low NOx heater can be "doubled up" on the red,terminal bar with the four wires coming from the indoor controller. NOTE: If you need to install more than two wires in each terminal, order a Jandy Multiplex PCB Kit, which includes the Multiplex Board (Jandy part # 65.84). Never put more than two wires into each of the pins of the terminal bar. On the heater's electronic control board, verify that the water temperature sensor is connected (J4-1 & J4-2), and that jumper is in place on W0. 8. Check all wiring, then apply power to both the heater and the RS control system. Operation can be verified in either Service or Auto mode. See your RS Control System manual for°instructions about:operation. When the LX Low NOx.heater is first powered, thed.isplay on the control will show "RS ONLINE". If there :is an RS control connected to the heater, it will sense the RS unit and remain online. If an RS system is not connected to the LX Low NOx heater via the four conductor line, the message "RS ONLINE" will disappear after 15 seconds. When the display shows "RS ONLINE" all functionality of the control on the heater is disabled. The heater functions can be con- trolled only at the RS unit.. However; sensor data is displayed at both the heater and the RS unit. To temporarily use the heater controls, use the selector button to turn the heater from either "Pool" or "Spa" to "Off". The "RSIONLINE" indicator will disappear from the heater display. All functionality has now been returned to the control on the heater. In this mode the!RS unit is no longer controlling the heater. To return the functionality to the RS unit, use a thin object, such as a,paper clip or tooth pick, to depress the button marked "RS SERVICE". An interrupt (on/off) type remote can be con- nected by -removing the jumper wire on the terminal block located in the control compartment (see Figure 2 1 ) and connecting the two wires from the remote to the two terminals on the terminal block. This type of remote control will turn the heater on or off, but will not perform any other function. This type of connection may be used to connect a Jandy AquaLink RS Control System utilizing any revision level programmed control chip. The control will automatically turn the heater on and off and will display the pool water temperature, but all other functionality and display informationwill be inactive. When using'this type of connection, rememberto set the LX heater's control to either "Pool" or "Spa" and set the corresponding thermostat control to maximum. Consult with our Service Department for ques- tions about installing remote controls manufacturedby companies other than.Jandy. SECTION 7.

Operating Instructions 7.1 Normal Operation The LX and LT-Low-NOx heaters are capable of automatic operation based on a call for heat at preset temperatures and an operator selection between pool or spa settings. Additionally, the heater may be controlled'by a remote unit to anticipate bather load, changes in temperature settings, or a variety of other demands that might be encountered. The heater has an LX,and LT Low NOxA.S.M.E. Pool/Spa Heater Page23 internal safety system which allows operation in a variety of conditions and prevents operation when. certain adverse conditions are encountered. The heater is capable of diagnosing problems within the safety controls scheme, enabling faster service and less down time in the event of a failure. When the heater is powered, water is flowing through the heater, and the temperature of the water entering the heater is below the temperature control setting; an operating cycle is initiated by the automatic control. The combustion blower is started and operates at high (normal) speed. If the blower pressure switch senses adequate airflow, the ignition sequence starts. First, a fifteen second pre -purge takes place. Next, the blowerspeed is reduced and the igniter is ener- gized. After forty seconds of igniter heat -up time the gas valve is opened (approximately one minute after the call for beat). If flame is sensed at the burner within seven seconds, operation continues and the blower resumes high.(normal) speed. Operation will continue until the temperature of the water entering the heater reaches the temperature control setting. If ignition is unsuccessful,.or ifthe.flame fails during normal operation, the ignition control shuts off the gas valve. It imposes a post purge, initiates addi- tional ignition cycles, and shuts down the system'if ignition is not achieved in. three cycles. To reset the model LX Low NOx for another three cycles, press and release the mode button until the indicator on the LCD screen aligns with "OFF". Now press.and release the button again until the indicator on the LCD screen, aligns with the desired setting, either "POOL" or "SPA". To reset the model LT Low NOx, press and release the mode button until the indicator lights for the "SPA" and "POOL" settings are off. Then press and. release it again until the indicator light for the desired setting is back on. 7.2 Start -Up ®WARNING For your safety, when starting the heater, keep your head and face well away from the burner area to prevent any risk of personal injury.

Parte 24 Be sure that there is water in the pool and that the surface level is above the skimmer or other inlet of the pool's filter system. Confirm that pool water is flowing normally through the pool system and equipment. With any new pool or spa installation, operate the filter pump with the heater off long enough to completely clean the water. This will remove any installation residue from the water. Clean the filter at the end of this operation before starting the heater. Start the heater in accor- dance with the Operating Instructions section of this manual, with particular attention to the lighting and shutdown instructions and temperature control opera- tion. The heater may not start on the first try. Air in the gas line or other start-up situations may cause it. to cycle. It will lock out:if ignition is not achieved in three attempts (see Section 9.2, "Service Codes"). To provide three additional attempts, use the mode button and follow instructions in section 7.1 to reset the controller. When the heater starts, immediately feel the outlet header of the heater to confirm that there is adequate water flow. The header should not be hot. Normally, water temperature will rise only a few degrees as it passes through the heater, and a "hot" header or pipe indicates low water flow. A WARNING When the heater is fired for the first time, the combustion chamber refractory binder material is driven out by the heat of the flame: White smoke and/or sharp odors may be emitted from the vent during this period. Do not inhale combustion product fumes at any time, and especially when these fumes are being emitted. This "burn -in" period will last only a few minutes. A AVERTISSEMENT Lorsque I'appareil est mis.en marche pour la premiere foist ie, materiau liant refractaire de la chambre de combustion est expulse par la chaleurde la flamme.

Cette periode de combustion ne durera que quelques minutes; When raising the temperature of a cold pool, program the time clock to turn the pump off 23 hours after the start time (e.g., If the starttime. is 2:00 PM, then set the stop time at 1:00 PM.). This lets the filter system and heater operate continuously until the water reaches the temperature setting on the temperature. control. When that happens, the.heater will automati- cally shut off, but the filter pump will keep running. 7.3 Temperature Controls The LX and LT Low NOx heaters have tem- perature controls that can be set to heat the pool and spa with. independent temperature settings. The controls display information to indicate that the heater needs service, and diagnostic information for the service person (see Figure 24). The LX utilizes a liquid crystal display (LCD.) screen to display the informa- tion while the LT uses indicator lights. The LX Tem- perature Control also displays pool/spa water'tempera- ture and allows for precise temperature settings of the heater. The controls allow the heater to directly interface with all Jandy remote control units. The LX offers full remote control capabilities while the LT controls offer limited remote control. Important: The temperature controls cannot be calibrated in the field. If the control is faulty, shut down the heater by following the procedures in Section 7.4 and have a qualified service technician replace the control. DO NOT use the thermostat switch to completely shut down the heater. 7.3.1 Information Displayed The Model LX displays information on a Liquid Crystal Display (LCD) screen. The temperature control displays the water temperature of the pool or spa as well as the desired temperature (thermostat setting) in either Fahrenheit or Celsius. When there is water flowing through the heater (the filter pump is on), the water temperature is displayed in the right- most of two bar graphs in the center of the screen. This bar graph is labeled as `Water Temp'. The selected thermostatic setting (either Pool or Spa) is displayed as a bar graph directly to the left of the water temperature bar graph. This bar graph is labeled as `Thermostat Setting'. Note that when neither thermostat is selected (the, heater is in off mode) only the water temperature is displayed. If there is no water flowing through the heater (the filter pump is ofd, then only the thermostat setting for the mode selected, pool, or spa, will be displayed. The Model LT heater does not display water temperatures or thermostatic settings. When the heater is unable to operate due to a problem,.the temperature control will identify which limit.is.not satisfied. The Model LX displays this. information on the left side of the LCD under the LAARS LX logo. When the gas heater is firing, the LCD displays. `Heating' under the LAARS LX logo toward the center of the upper portion of the screen. The Model LT displays this information by lighting a set of indicator lights located on the front of the control panel. LX and LT Low NOx A.S.M.E. Pool/Spa Heater Page 25 Figure 24. Temperature Control'Panel On the upper right-hand portion of the LCD screen on the Model LX is a selector arrow. Directly to the left of the selector arrow are three positions. They are `POOL', `OFF', and `SPA'. This part of the display indicates the mode of operation in which the heater is set. The mode of operation of the Model LT is shown by two indicator lights labeled "SPA" and "POOL" Underneath the mode selector on the Model LX display screen is a Backlight indicator. To turn the backlight on, press the middle button to the right of the screen, labeled "Backlight". Below the Backlight indicator is an. RS service indicator, which displays "RS Online" when the heater is connected to an RS unit. Directly below the RS Service indicator on the bottom right hand portion of the LCD screen is the Fahrenheit/Celsius temperature unit indicator. The Model LT does not offer these features. 7.3.2 Turning the Heater On or Off When power is supplied to the Model LX heater, the control goes into a diagnostic modefor approximately 15, seconds beforer the heater can be turned to the Pool or Spa mode. During this time the display will show "RS Online". If there is an RS control connected to the heater, it will sense the RS unit and remain online. If the control is not connected to an RS unitthe "RS°Online" indication on the .display will disappear after the initial 15 seconds. When the display shows "RS Online" allfunctionality of the control at the heater is disabled. The heater functions can be controlled only at the RS unit. However, sensor data is displayed at both the heater and the RS unit. (See Section 6.5 "Remote Operation"). When power is first supplied to the Model LT heater, it also runs through a circuit board diagnosis to make sure that the control is working correctly. Indicator lights will flash.during the 10 second diagnos- tic sequence. After the initial diagnostic sequence on the Model LX, the heater can be turned to Pool or Spa mode by pressing and releasing the top (mode) button 'to the right of the LCD screen so that the selector arrow is aligned with either the Pool or Spa setting as seen on the LCD screen. To turn the Model LT heater on, press and release the button located between the "POOL" and "SPA" indicator lights. Repeat pressing the button to achieve the desired mode of operation shown by the indicator lights. When neither light is on, the heater is "0FF91 It is now .necessary to set the thermostat to the desired pool or spa setting. Page 26 andy. 7.3.3 Setting Pool and Spa Temperatures, Changing from Fahrenheit to Celsius The Model LX heater displays temperature in. Fahrenheit units when powered -up. To switch to Celsius, first turn the heater to the "Off' mode, then press the `F°/C°' button. Once the desired tempera- ture units are selected, the thermostat can be set. The left-most button below the LCD screen, labelled "Select", will select either the Pool or the Spa thermo- stat when depressed. Either "Pool" or "Spa" will be displayed in the bottom left corner of the LCD screen. The `up' and `down' buttons will increase or decrease the thermostat setting. The Model LT heater control is less quantitative and less automatic. The pool or spa water temperature will need.to be monitored manually when the control is adjusted. Temperature adjustments are: made by turning the knob associated with the mode labeled below it. Turning the knob clockwise will increase the temperature setting. Turning it counterclockwise will decrease the setting. Once the desired setting is achieved, set the temperature lock by loosening the screw located at the bottom of the knob and rotating the dial stop counterclockwise until it contacts the knob. Tighten the screw to lock the stop in place. When the thermostat setting exceeds the tem- perature of the pool or spa, the heater will fire. The heater will fire continuouslyuntil the pool or spa Water is heated to the selected thermostat temperature. The control will not allow the heater to fire again for five minutes even if there is a call for heat, unless the thermostat setting is increased. In this case; the heater will .fire within two minutes. This is to prevent short - cycling, and thereby increase the life of the heater. When the Model LX heater is firing, "Heating" will be displayed underneath the LAARS LX logo. Now that in both the "POOL" and "SPA" thermostat settings, the temperature cannot be raised above 104°F (40°C). Note that if power is momentarily lost, the thermostat settings will remain the same. Also note that the heater should not be used to maintain water temperatures at or below 70°F (21 °C). This will damage the heater. 7.4 Lighting and Shutdown Procedures A WARNING Do not attempt to light the heater with the door off. Doing so may cause severe bodily injury.

Adjust the pressure switch only if any part of the filter system piping is,3 feet (0.91 m) or more above the top. of the heater jacket. Do not adjust the pressure switch if the heater is installed more than 15 feet (4.57 m) below or 6 feet (1.83 m) above the pool surface. Consult your local Jandy representative for recommendations. On some installations, the piping from the heater to the pool is very short. The back pressure could be too low to trigger the pressure switch. If this happens, it may necessary to install a directional fitting or elbows where the return line enters the pool. This will increase back pressure enough for the heater to operate properly. Make sure the pool filter is clean before making any pressure switch adjustment. A dirty filter will restrict the water flow and the pressure switch cannot be adjusted properly. To adjust the pressure switch; proceed as .follows (see Figure 27). 1. Set the heater control to the "OFF" position. 2. Start the filter pump and confirm by means of a voltmeter that the pressure switch closes (if the switch fails to,close, replace it with a switch that has a.lower minimum setting). 3. Set the heater control to either Pool' or 'Spa'. Heater should start. 4. Pry out the top rubber dirt plug on the pressure switch. 5. Use a 7/32 inch Allen wrench to turn the adjustment screw very slowly clockwise until the heater goes off. 6. Slowly turn the pressure switch adjustment screw counterclockwise one-quarter turn. The heater should come back on. 7: Check the adjustment by turning the filter pump OFF. The heater fan will continue to run but the burners should shut.off immediately. If they do not, restart the filter pump and repeat Steps 6 and.7. Check. the adjustment again. 8. Return the pool temperature control to the desired temperature. It may be necessary to repeat these steps to get 'a proper setting. The switch must be set so that the heater will not fire unless the pump is running: If a proper setting cannot be reached, contact the factory service department. PRY OFF CAP TO ADJUST PLUG.

Pool/Spa Heater 7.6 Temperature Rise A temperature rise test confirms proper water flow through the heater. The temperature.- rise is the difference between the temperature of the pool or spa water before and after heating, as measured in the header. The: Laars LX and LT Low NOx pool and spa heaters have an internal bypass which accommodates a wide range of water flow. The bypass assures constant heat exchanger flow even though flow through the filter system will vary depending on how dirty the filter is. For most.installations, an external bypass valve is not needed in the heater water piping. This is due to the large size of the heater's internal bypass valve. If the pump flow rate is known.to significantly exceed 125' gpm (7.91/0, an external bypass may be needed to assure proper heater operation. Water flow should be confirmed upon start-up of the heater and in most servicing situations. If the flow is not.normal, corrections must be made to the pool system. blow is evaluated by determining the water temperature rise through the heat exchanger. Before checking the temperature rise, make sure that the pool filter is clean. If necessary, clean all components of the filtersystem. Temperature rise is measured in the outlet of the far -right tubes when facing the inlet/outlet water heater. A temperature rise measurement kit is available through,your Jandy distributor. See Section 11 ofthis,manual for the correct kit number. To adjust the temperature rise to within the ranges specified in Table 7, proceed as follows: 1. Make sure that the pool frlter.is clean. 2. Turn off the filter pump at the circuit breaker. 3. Set the heater's control panel to the "OFF" position. 4. Remove the drain plug located on the inlet/outlet header of the heater and replace it with a Pete's plug (see Figure 28). 5. Insert a pocket thermometer (see Figure 28) through the.Pete's plug into the header. 6. If the piping, system has an external bypass valve,. close it. 7. Turn the filter pump on and wait 3 minutes. The heater remains off. This allows water from the pool to reach the heater. 8. Record the temperature indicated by the ther- mometer (cold water). 9. Start the heater by setting the control panel to "SPA". Page 29 Figure 28. Temperature Rise Measurement 10. Set the thermostat for the spa temperature to the maximum.. 11. Allow the heater to run for about 5 minutes. Record the new temperature reading (heated water). 12. Subtract the first temperature reading (cold water) from the second temperature reading (heated water). The difference between the two readings is the temperature rise. The tempera- ture rise should be within the range shown in Table 7. Table 7.

If the temperature rise.is below the minimum range indicated, check for the following: a. The supply gas volume may be too low. b. The system's water flow exceeds_ 125 GPM (475 LPM), and requires a manual bypass valve for proper operation. Install a manual bypass (see Figure 9 on`page 13) and proceed to Section 7.8. c. The heater's internal bypass may not be operating properly. Rage 30 andy. 14. If the temperature rise is above the maximum range indicated, check for the following: a. The:supply gas volume may be too high. b. The system's water flow does not meet the heater's minimum flow requirements. This may be caused by an incorrectly adjusted manual bypass (see Section 7.7 for proper adjustment procedure), clogging or restrictions in the filter or piping, or an undersized pump. c. The heater's internal bypass may not be operating properly. A CAUTION Operating the heater with the temperature rise above maximum or below the minimum can damage the heater and may void the warranty.

If the temperature rise is within the correct range, complete the procedure, As follows: a. Set the controller to 'OFF' . b: Turn off the power to the filter pump at.the circuit breaker. c. Remove thermometer and Pete's plug. d. Replace the drain plug. e. Turn on the power to, the filter pump at the circuit breaker. f: Return the spa thermostat control to the desired temperature. 7.7 Adjusting the Manual Bypass Valve After the.manual bypass valve is installed, use the following procedures to adjust thebypass valve: Make sure the pool filter is clean. 2. Turn off the filter pump at the circuit breaker 3. Remove the drain plug located on the inlet/outlet header of the heater and replace it with a Pete's plug (see Figure 28). 5. Insert a pocket. thermometer (see Figure 28) through the Pete's plug into the header. 7. Close the manual'bypass valve. 8. Set the heater's controller to 'OFF'. 9. Repeat steps 7 through 12 of the temperature rise test (see Section 7.7). 10. If the temperature rise is below the minimum stated in Table 7, open the, manual bypass valve until temperature rise -climbs between the min. and max.. range for your size heater. If the minimum temperature rise:stated in Table 7 cannot be reached withthe manual bypass fully open, then the gas supply volume is too low or the heater's internal bypass in not:working correctly. 1.1. If the temperature rise is above the maximum, there isnot enough water flowing through the heater. Check for clogging in the filter, restriction in the water pipes or an incorrectly operating internal bypass valve. Also check that the gas supply volume is not.too low. 12. Once the temperature is within the correct range, safetywire the handle ofthe manual bypass valve in place and tag the valve to prevent change in the water flow. 13. Complete:the procedure as follows: a. Set the heater's controller to 'OFF' b. Turn off the power to the filter pump at the circuit breaker. c. Remove ,thermometer and Pete's plug. d. Replace the drain plug. e. Turn on the power to the filter pump at the circuit breaker. f. Return the spa thermostat control to the desired temperature. SECTION 8. Maintenance 8.1 Water Chemistry The mineral content.of swimming 'pool water increases daily due to natural evaporation and the addition of sanitizing.chemicals. If the mineral concen- tration in the pool gets too high, the excess minerals will deposit on the walls of the pool, in the filter system, and in the heater tubes. LX and LT Low NOx A.S.M.E. Pool/Spa. Heater Page 31 The proper chemical balance in spa water is more critical than in a swimming pool heater operation. Due to the spa's size, high water temperature and heavy usage, chemical values in a spa can vary greatly.. This chemical imbalance can result in unsani- tary water conditions, and affect the life of the heater. Proper chemical balances are necessary for sanitary bathing conditions as well as ensuring your heater's long life. Kits are available from your local pool supply dealer for making the various tests for mineral content. One of these kits will detect copper in the system. This is usually a warning that corrosion is taking place, possibly due to a low pH value combined with other chemistry problems. The condition can be corrected by changing the spa water and closely monitoring the pH factor and chemical properties of the water. Be sure to keep your chemical levels within the values indicated in Table 8. Water Pik Technologies does not warrant heat exchangers damaged by corrosive chemical levels or excess dissolved solids in pool or spa water. For spas, it is also necessary to perform water changes in addition to chemical treatment. It is recom- mended to change the spa water every 60 days for light usage and every 30 days if usage is heavy. Table 8.

See Section 7.3.3. This prevents the pool water from becoming chilled, and minimizes the time required to raise the pool water back up to the desired temperature. If the heateris not going to be used for a long period of time, shut it down completely. Follow the instructions found on the inside of the heater, or Figure 25 on page 27 of this manual. 8.2.2 Winterizing In areas where freezing temperatures occur in winter and the pool or spa will not be used, have your service technician perform the following steps: Turn off the main gas supply to the heater, using the gas cock outside the heater jacket. 2. Remove heater door. 3. Shut down the heater following the shutdown instructions found on the inside of the heater or Figure 25 on page 27 of this manual. 4. Remove the drain plugs from both the inlet/outlet header and ,the return header (see Figure 29), and completely drain the heater before the first frost. Figure 29. Draining the Heater 5. After all water has drained from the heater, check for mineral buildup in.the openings. 6. Usecompressed air to blow out any standing water remaining in the heat exchanger. 7. Apply grease to the threads of the drain plugs and reinstall plugs, but do not tighten. Disconnect the pressure switch fronf the siphon tube (copper tubing) (see Figure 30). 32 SYPHON PRESSURE TUBE SWITCH DISCONNECT HERE (WINTERIZING) Figure 30. Winterizing the Pressure Switch 9. Cover the vent grill so that snow will not accu- mulate in the combustion blower, where it may freeze. 8.2.3 Spring Start-up To restart the heater in the Spring, have a qualified professional technician reassemble the heater as follows: Attach the copper tubing to the pressure switch (see Figure 30). 2. Tighten the drain plugs. 3. Uncover the vent grill. 4. Make sure that power is supplied to the pump. Turn on the filter pump and circulate water through the heater for 5 minutes. Check for leaks while circulating. Turn on the main gas supply to the heater at the gas cock outside the heater jacket. 6. Turn on the heater following the lighting instruc- tions found on the inside of the heater, or Figure 25 on page 27 of this manual. 8.3 Inspection and Service The Laars LX and LT Low NOx heaters are designed and constructed to provide long performance life when installed and operated properly under normal conditions. Periodic inspections, especially at spring start-up, are important to keep your heater running safely and efficiently through the years.

If the heater is equipped with a pressure relief valve, check for corrosion in and around the valve. Twice a year, with the filter pump on, lift the release lever on the top of the valve to make sure that water runs freely through it. If corro- sion is found, replace the pressure relief valve. When replacing the valve, be sure that the pump is off. Install the valve so that thedischarge is directed away from any area that may be damaged by water. LX and LT Low NOx A.S.M.E. Pool/Spa Heater . Page 33 6. Be sure all combustion air and ventilation open- ings are not blocked. Check for spider webs and other debris inside the heater, in the vents on all sides of the. heater jacket and in the exhaust. outlet— especially after a long period of nonuse. 8.3.2 Professional Inspection Inspections performed at least once a year by a qualified technician,are required to maintain your heater's safe and efficient operation. The following basic safety checks must be performed. 1. Check for loose or broken wires and terminal connections. 2. Make sure that the pressure switch operates properly'by shutting the filter pump off and on a few times. The burnershould go,off immediately after the pump stops. An ignition sequence should start shortly after the pump is turned back on. 3. Inspect the electrical controls, specifically the following: a. High limitcontrols. b. Water pressure switch. c. Exhaust temperature limit switch. d. Automatic gas valve. e. Fusiblelink. f. Temperature control. g. Control circuit fuse. h. Ignition control. i. Air pressure switch. 4. Inspect the venting system for blockage, leakage, and corrosion. 5. Inspect the combustion blower for damage. 6. Check for spider webs or other obstructions in the main bumer orifices— especially at Spring start-up. Clean with wire brush if necessary. 7. Conduct a normal operating cycle and observe that the sequence proceeds as intended. A CAUTION For your safety, when starting the heater, keep your head and face away from the burner area opening to prevent any risk of personal injury.

NOTE: After installation and first start-up,. check the heat. exchanger for black carbon soot buildup after the following periods of operation: 24 hours; 7 days, 30 days, 90 days and once every 6 months thereafter. NOTE: Keep this manual in a safe place for future reference by you and your professional technician when inspecting and servicing the heater. SECTION 9. Troubleshooting 9.1 General Heater Troubleshooting Table 10 lists some of the, more common prob- lems, causes and solutions encountered when running the heater. Most problems occur when the heater is being started for the first time after installation or at Spring start-up. Careful.installation and maintenance will help ensure years of trouble free use from your Laars LX or LT Low NOx heater. 9.2 Service Codes The Laars LX and LT Low NOx controllers monitor several functions of the heater. In the event of a malfunction, the LX controller will display°a service code on the left side of the LCD screen under the LAARS LX logo (see Figure 33). The model LT displays this information by lighting a set of indicator lights located on the front of the control panel (see Figure 34). Table 11 lists the LX. and LT Low NOx Heater Service Codes along with potential causes and remedies. Note:: When the service codes marked with an asterisk (*) are displayed, the controls are still operable and the heater will operate normally when the displayed, condition is remedied. Fault codes without an asterisk (*) will shut down the heater and control panel, and a flashing "Service" icon will be displayed. 9.3 Ignition Control LED Service Codes In addition to the service, codes shown in the previous section, the ignition controller in both the LX and LT Low NOx model heaters has an LED light that flashes to indicate various different. faults.

Professional Maintenance and Service A WARNING SERVICING SAFETY Some of the servicing procedures for the Laars LX and LT Low NOx heaters are hazardous because they involve fuel gas, electricity, moving parts and procedures which require testing or temporary bypass of safety controls. For this reason, the heater must be serviced only by a qualified professional service technician. IMPROPER. SERVICE HAZARD The Laars LX and LT Low NOx heaters incorporate unique design features. Incorrect service of this heater can result in personal injury or damage to property. To avoid such hazards, the heater must be serviced only by a qualified professional service technician.

Before calling for service, however, the owner should check for obvious prob- lems.. The other components -in the pool system, including pump, filters and strainers, water valves, gas supply, electrical power and time clocks, have an affect on heater operation. Confirm that the heater control is set to either POOL' or'SPA' and that the corresponding tempera- ture limit is set high enough to make the heater operate. Make sure the pump is operating, that the filter and all baskets are clean; that there are no mis- positioned water valves, that the gas or electric power supplies are not shut off and that time clocks are properly adjusted. Also be sure that there is no blockage of the exhaust vent grill or rear louvers, which supply combustion air to the burners.. 10.2 Induced -Draft Combustion System The Laars LX and LT Low NOx pool and spa heaters have an induced -draft combustion system incorporating special burners and a combustion blower. The burners are of special design in which most of the combustion.air passes through the burners, resulting in a "premix process. When burning natural gas this process produces very low NOx emission. This system .is illustrated in Figure 35. Figure 35. Induced Draft combustion System Page 38 �andy. The system operates with a balanced combina- tion of natural and induced draft. Air and gas are pulled into the burner venturis where they are mixed and conveyed to the combustion chamber. The combustion process produces heat and creates a negative pressure or "draft" condition. A small amount of secondary air is pulled into the chamber through holes and openings provided forthat purpose. Hot combustion products pass through a highly efficient heat exchanger, where water absorbs most of the heat. Cooler products continue on and are pulled into the combustion blower, which exhausts them and stabilizes system flow. Exhaust is directly to the outdoor air through a grill, or for indoor heaters, through ventpiping. 10.3 Heater Components and Their Operation Gas Valve / Regulator - The gas valve controls gas flow into the manifold. It provides flow only when the temperature control requires heat and only if all safety controls enable operation. Itis also a positive pressure regulator. It regulates the gas pressure: in the manifold to specifications addressed earlier in this manual. This is neces- sary for proper operation of the burner system. 2. Temperature Control - Both the LX and LT Low NOx heater models are equipped with an electronic control which senses water tempera- ture by means of a thermistor and controls heater operation to bring the water to the temperature selected. It has an option for two separate thermostat settings which are typically used to set pool and spa temperatures. Ignition Control - The ignition control provides energy for ignition of the air/gas mixture, moni- tors the flame and controls the gas valve. When the temperature control requires heat, the ignition control provides a pre -purge of 'the combustion chamber. Once the pre -purge is complete the ignition control lowers the blower speed and then applies electrical power to a "hot surface" igniter. When the igniter is hot enough, the ignition control opens the gas valve. It has sophisticated means to sense ignition and flame condition so that unburned gas will not escape. Once the ignition control -has sensed flame, it de -energizes the igniter and returns the blower tofull speed. After the burner is shut off, the ignition control continues blower operation to provide a post - purge period. 4. Igniter - The hot surface igniter is.a crystalline element which becomes very hot when electrical power is applied to it. The hot surface igniter directly ignites the air/gas mixture in the combus- tion chamber. 5. Limit Switches - Two limit switches prevent excessive water temperature - one within the heat exchanger and one for water leaving the heater. If either senses excessive temperature, burner operation is interrupted. 6. Water Pressure Switch - This control senses whether or not water is available to the heater by measuring back pressure- inside of the heat exchanger. If the pool water pump fails or the water filter is blocked, the pressure switch prevents operation of the burner. 7. Fusible Link - This is a single -use, switch which detects abnormal temperature in the component compartment of the heater. It is. a fusible link which is held to the combustion chamber just above the burner tray by a sheet metal bracket. Excessive temperature in the component com- partment, possibly due to a burner flash -back will cause the link to fail. This opens the safety circuit which shuts off the gas valve and shuts the. heater down. 8. Air Pressure Switch - This switch verifies that air is -flowing through the combustion system by sensing pressure. It shuts off the heater if air flow is inadequate. 9. Flame Sensor - The flame sensor is the elec- trode through which the ignition control detects. "rectification" of current passed through the flame. Inadequate rectification indicates an unsatisfactory flame. condition. The rectification signal can be measured by attaching the leads of a DC ammeter to the two pins on the connector of the ignition control labeled "FC". A wire harness, available from ]andy, makes it easier to attach the voltmeter leads. The flame current should not be less -than 1.5 micro -amps. If the flame signal is less than L5 micro -amps, you can adjust the throttle strip on the burner tray to allow more air into the combustion chamber. This can increase the flame signal. 10. Exhaust Temperature Limit Switch - A manually resettable limit.switch prevents exhaust temperatures in excess of 240°F (l 160C). If it senses excessive temperature the switch opens and burner operation is interrupted. Once the cause of the excessive exhaust temperature has been corrected, the switch may be reset and used again. LX and LT Low NOx A.S.M.E., Pool/Spa Heater Page 39 10.4 Electrical Troubleshooting This section describes, procedures for checking the electrical power and control components of the heater one at a time and in the order they appear in the control circuit. It is important to follow the sequence of this trouble shooting guide because the safety circuit is connected in series. These procedures require a Volt -Ohm meter with a minimum 0-250VAC voltage range, and 1-1000 Ohm resistance range. Figure 36 shows the power and control circuits and where to take measurements. Location numbers in circles have been added, and will be referenced in the following sections. Where test points are shown at circuit board connectors, the probe of the meter can be carefully pushed into the connector along side of the wire at the connection to be measured. The electrical power supply can be checked with the heater not. set to fire. All other procedures need to be checked with power correctly supplied to the heater, all external devices set so that the heater is allowed to fire and the heater's thermostat set so that there is a call for heat. As stated at the beginning, of the manual, some of these procedures are. hazardous. Only a qualified service technician should service the heater. 10.4.1 Electrical Power Supply The electrical components of the Laars LX and LT Low NOx pool heaters are designed to operate with supply voltage ranging from 98V to 126V at 60 Hz if connected to a nominal Il 5 volt.power supply; or 196V to 253V at 60 Hz if connected to anominal 230 volt power supply. Measure supply voltage at the power supply leads where they enter the heater (identified as points A, B and C on the wiring diagram in Figure 36.).. Use the voltages in Table 12 to verify that the correct voltage is supplied to the heater. Table 12. Supply Voltage Measurements MEASEURE EXPECTED EXPECTED BETWEEN VOLTAGE WITH VOLTAGE WITH THESE VOLTAGE WITH VOLTAGE WITH POINTS 230V SUPPLY 115v SUPPLY A and B 98 - 126 Volts 0 A and C 98 - 126 Volts 98 - 126 Volts B and C 196 - 253 Volts 98 - 126 Volts 1: Point A Is the ground connection on- the heater. 2. POhlt B Is the locattomat which the red power lead enters the power circuit board. 3. Point C Is the location at which the black power lead enters the power circuit board If no voltage is present, correct this external power supply problem to the heater. Circuit breakers, time clock, settings or similar devices may the problem. Voltage outside of the above ranges may be due to poor wiring, poor connections, other loads, such as air conditioning compressors, or to an electric utility company problem. Arrange for correction of the voltage as appropriate. When you are sure that the voltage supplied to the heater is correct, check the voltage being supplied to the transformer by the power supply circuit board. This can be done by measuring the voltage between the wires of the four -pin connector on the power supply circuit board. Thesepoints are designated as test points D, E, F, and G on Figure 36. The voltages measured between any two of these four points will be determined by the voltage supplied to the transformer (see Table, 13 for expected voltages). If the voltages. measured do not fall within the limits shown.in Table 13, then there is a problem with the power supply circuit board and the board must be replaced.. Table 13.

Point.F is the location at which the red wire enters the 4 pin connector. 4. Point G Is the location at which the black wire enters the 4,pin connector. 10.4.2 Controller The controller must be operational in order to check the control circuits of the heater. 10.4.3 Control Circuit Troubleshooting The heater controls are arranged in several 24V 60Hz circuits with some.operating and safety controls arranged in series circuits. Troubleshooting is done by probing for voltage between the common and;various points in the circuit to determine which component is preventing operation. Check points;are indicated on Figure 36. The black Page40 J�4ndy lead of the meter should be attached to the common tap on the secondary side of the transformer and may be left there throughout most of the procedure. The recommended procedure steps through each circuit in a.sequential way, and each section assumes that components from all previous sections have'been tested and are operational. However, verifying voltage at any of the numbered points in that circuit confirms that all prior components of the circuit are operational. 10.4.3.1 Transformer Attach the black lead of the voltmeter to the terminal on the.secondary side of transformer with a yellow wire attached to it (common). This is test point 1 on Figure 36. Touch the free lead of the voltmeter to the terminal on the secondary side of transformer with a red wire attached to it (24V tap), test point 2. The voltmeter should read between 2.0-28 Volts. Leave the black lead of the meter on the common tap (test: point 1), and move the free lead of the voltmeter to the terminal on the secondary side of transformer with a white wire with yellow tracer attached to it (12V tap), test point.3. The meter should read 10-14 Volts. If the voltage at either of the test points does not fall within the limits mentioned. above replace the transformer. 10.4.3.2 Fuse Leave the black voltmeter lead in place at test point 1. Touch the free lead of the voltmeter to test point 4, which is on the back of the controller where the red wire from the transformer enters the end of the connector. You will. need to push the voltmeter lead into the back of the connector along side of the I ire pin. The meter should read 20-28 Volts. If there is no voltage, the fuse has failed. Inspect the rest of the wiring, especially the safety circuit, to be sure that there is no "short" such as contact of a terminal with the heater chassis or another terminal which may have caused the fuse to fail. Correct any such condition and replace the fuse. Use only a 2 amp, 1 1/4" long x 1/4" diameter, quick:acting, glass tube type fuse. A 4 amp fiise is used when an EZ Switch Kit is installed. 10.4.3.3 Water Pressure Switch/External Interlocks or Fireman Switch Circuit Start by checking the voltage at the two legs of this circuit at the back of the controller, (see test points. 5 and 6 in Figure 36). Leaving the black lead of the meter on test point 1, check the voltage at test point 5, where the black wire from the pressure switch enters the ten -pin connector on the back of the controller. If there is not 20-28 Volts at this point, either the control- ler or the ten -pin wire harness is faulty and must be replaced. If 20-28 Volts is detected at test point:5, then move the red lead of the meter to test point 6 where the white wire from the fireman switch terminal block enters the ten -pin connector. if 20-28 Volts is detected at this point, the devices in this circuit are closed and the circuit is working properly. If there is no voltage, either the pressure switch contacts or the contacts of the external switch (fire- man switch) are open. To determine which device is causing the fault, move the red lead of the meter to the contact on the water pressure switch where the black wire is connected, (test point 7). Voltage to this point means that the wire harness between the controller and the water pressure switch is good. If there is no voltage..at test point 7, look for a loose connection or replace the ten -pin wire harness. If there is voltage at test point 7 then move the lead from test point 7 to the contact on the other side of the water pressure switch (test point 8). No voltage here means that the pressure switch contacts are open. This is almost always due to a water flow deficiency, the most common one being a blocked water filter or defective pump. However, sometimes it is due to blockage of the copper siphon loop tube or mis-adjustment of the switch. Investigate thoroughly, referring to Section 7.5 on "Adjustment of Pressure Switch". If there is no problem with the pool system or pressure switch adjustment, replace the pressure switch. If test point 8 shows 20-28 Volts, check the voltage going to the external device. Move the lead of the meter to the lower right terminal screw on the fireman switch terminal block (test point 9). No voltage means that there is a bad connection in the wire between the. water pressure switch and the terminal block. If 20-28 Volts is shown here, it ensures that the correct voltage is being supplied to the exter- nal switch. Now'move the lead to the upper right terminal screw on the terminal block (test point 10). No voltage here means that the external device is not working properly. The time clock switch or other external interlock may be mis-adjusted, mis-connected or defective. Correct this external problem. If there is 20-28 Volts at test point 10 then there is.a bad connec- tion between the terminal block and the controller. Replace the ten -pin connector wire harness. 10.4.3.4 Temperature Limit Switches Circuit.. Since the limit switches are not easily accessible, you can check the voltage between test point 1 and the two legs of the circuit at the controller (see test points 11 and 12 in Figure 36). Leaving the black lead of the meteron test point 1, check the voltage at test point 11, where the white wire from the 1.50° limit switch enters the ten -pin connector on the back of the controller. If there. is not 20-28 Volts at this point, either the controller or the ten -pin wire harness is faulty and must be replaced. If 20-28 Volts is detected at this point, then move the red lead of the meter to test point 12where the white wire LX and LT Low NOxA.S.M.E. Pool/Spa Heater Page 41 from the .135° limit enters the ten -pin connector. If 20- 28 Volts is detected at this point, the devices in this circuit are closed and the circuit is working properly. If there is no voltage, one of the limit switches is open. This is normally due to excessive water tem- perature, which should be thoroughly investigated before replacement of limit switches. Excessive water temperature may be caused by low water flow. Water flow deficiency may be due to obvious problems such as a defective pump or blocked water filter. Alterna- tively, excessive water temperature may be due to over -firing, or to a problem with the water piping or the heater's internal bypass control. Over -firing might be a result of an incorrect gasorifice or supply of propane gas to a heater intended for natural gas. If there are no such fundamental problems, identify which of the switches.is open. Limit switch access is through the limit switch covers on the, side of the, heater to which water pipes are connected. Remove the limit switch covers from the header and gently remove the.switches from the wells. Note that the limit switches have different trip points, and it is important that replacements are correct. The 150°F switch has a red dot on the top of the brass fitting, and must be installed in the lower (horizontal) well in the header. The 135°F switch has no dot and must be installed in the upper (vertical) well in the header. Leave one meter lead in place attest point 1. Move the other meter lead to the terminal connection on the 150° switch (test point 13) that is connected back to the controller.. The voltmeter should read 20-28 Volts. No voltage here means that the ten -pin wire harness is bad and should be replaced. If voltage is detected at this point -move the lead to the other terminal of the switch (test point 14). If the voltmeter does not show voltage then the 150° limit is bad -and should be. replaced. If the meter reads 20-28 Volts, move the lead to the terminal of the 135° limit that is connected to the wire that. jumps between the two limit switches (test point. 15)., No voltage here, means that the wire assembly is bad and needs to be replaced. 20- 28 Volts shows that the wire between the two limits is making a good connection. Now move the lead to the other connection terminal on the 135° limit (test point 16). No voltage at this point indicates that the limit switch has failed and needs to be replaced. Voltage here would show that the limit..is,good and that the ten- pin enpin wire harness may have a bad connection. Replace the wire harness if necessary. 10.4.3.5 Fusible Link,/ Exhaust Temperature Limit Switch Circuit Since the manual reset limit switch is not easily accessible, you can check the voltage between test point 1 and the two legs of the circuit at the back of the controller (see test points 17 and 18 in Figure 36). Leaving the black lead of the meter on test point 1, check the voltage at test point 17, where the white wire from the fusible link enters the ten -pin connector on the back of the controller. If there is not 20-28 Volts at this point, either the, controller or the ten -pin wire harness is faulty and must be.replaced. If 20-28 Volts is detected at this point, then move the red lead of the meter to test. point 18 where the white wire from the manual reset high limit switch enters the ten- pin connector. If 20-28 Volts is detected at this point, the devices in this circuit are closed and the circuit is workingproperly. If there is no voltage, either the fusible link or the contacts of the manual reset switch are open. To determine which device is causing the fault, check the fusible link first. Leave one lead of the meter at test point 1. Move the other lead of the meter to the contact on the fusible link where the wire is connected back to the controller, (test point 19). Voltage to this point means that the wire harness between the controller and the water fusible link is good. If there is no voltage at test point 19, look for a loose connection or replacethe ten -pin wire harness: If there is voltage at test point 19 then move the lead to the contact on the other side of the fusible link (test point 20). No voltage here means that the fusible link is open. This indicates higher than normal temperatures in the component compartment (vestibule). Normal component compartment tempera- ture is well below 300°F. The fusible link is designed to fail .at temperatures above 305°F. Excessive tempera- tures are almost always due to flashback conditions caused by a damaged burner,:manifold pressure being set too high or incorrect gas supply type. Check to be sure that the type of gas being supplied to the heater matches the designation on the rating plate. Thor- oughly inspect the burners and orifices for damage. Finally, check and adjust the manifold pressure if necessary. Replace the fusible link. If test point 20 shows 20-28 Volts, then the top of the heater must be removed to gain access to the manual reset exhaust limit switch. To check the manual reset switch leave one lead of the meter at test point l and place the other lead on the contact of the manual reset switch (test point 21') that is connected to the wire leading to the fusible link. If test point 21 does not show 20-28 Volts, then the wire assembly between the fusible link and the manual reset switch must be replaced. If 20-28 Volts is detected, then move the lead to the other contact of the manual reset switch (test point 22). Voltage here means that the ten -pin connector wire harness is faulty and must be replaced. If no voltage is detected, the switch contacts have opened due to excessive exhaust temperatures. This condition is usually caused by a blocked exhaust vent. Be sure that the vent is clear of all debris, then push the red button on the switch to reset the circuit. If there is still no voltage detected, the manual reset switch must be replaced. Page 42 �dy 10.4.3.6 Blower Pressure Switch Circuit The blower must be operating during the test procedure for the blower pressure switch. Start by checking the voltage between test point l and the two legs of this circuit at the back of the controller, (see. test points 23 and 24 in Figure 36). Leaving the black lead of the meter on test point 1, check the voltage at test point 23, where the purple wire from the blower pressure switch enters the ten- pin connector on the back of the controller. If there is not 20-28 Volts at this point, either the controller or the ten -pin wire harness is faulty and must be replaced. If 20-28 Volts is detected at this point, then.move the red lead of the meter to test point 24 where the black wire with a yellow trace from the blower pressure switch enters the ten -pin connector. If 20-28 Volts is detected at this point, the device in this circuit is closed and the circuit is working properly: If there is no voltage, the pressure switch contacts are open. Leave one lead of the meter at test point 1. Move the other -.lead of the meter to the contact on the blower pressure switch (test point 25) where the purple wire is connected. Voltage to this point means that the wire harness between the control- ler and the blower pressure switch is good. If there is no voltage at test point 25, look for a loose connection or replace the ten -pin wire harness. If there is voltage attest point 25 then movethe lead to. the contact on the other side of the blower pressure switch (test point 26)..No voltage here means that the pressure switch contacts are open. This is usually due to a blower speed problem or a problem with the air pressure tube connection between the blower housing,and the switch. Be sure that the blower is on and that it is working properly. Check that the gray flexible tube between the blower pressure switch and the blower housing 'is connected at both ends and has no holes or splits. Replace the tube if necessary. If there is no problem with the blower or the tube,. replace the pressure switch. If test point 26 shows 20-28 Volts, then there is a bad connection between the blower pressure switch and the controller. Replace the ten -pin connector wire harness. 10.4.3.7 Gas Valve Voltage The gas valve will operate only when there is a call for heat and All safety circuits have been satisfied If the gas valve does not operate under these condi- tions, check the voltage going to the gas valve. Place one voltmeter lead in the four -pin connector on the back of the controller where the yellow wire is con- nected (test point 27). Touch the free lead of the meter to the gas valve terminal where the brown wire is attached at the gas valve (test point 28). This test point wilthave voltage:present only during a trial:for ignition or during normal operation. The meter should read 20-28 Volts. If there is no voltage, then there is a bad connection between the gas valve and the control- ler. Replace the four -pin connector wire harness. Listen closely to the gas valve when it is first energized (24V first appears at test point 28 during the trial for ignition). There should an audible "click" when the valve opens. If there is voltage at test point 28, but the gas valve does not open, replace the valve. 10.4.3.8 Igniter/ignition Control Circuit ,AWARNING The igniter, power supply circuit board and some terminals of the ignition control utilize 115V or 230V power and require appropriate servicing precautions. Note that wires and terminals of these components may be "hot" even when the component is not operating.

Notei que les fls et les bornes de.ces cgmposants peu renf etre dhau&r meme s -i le composant, n61pnctionne .pas: - With the igniter leads connected to the power supply board there will be' voltage of 98-126 VAC between the quick disconnects at the ends of the igniter wires, test -point H and test point I, if the heater is connected to a 1 I 5 supply. If the heater is con- nected to a 230V supply then the voltage reading between these two points will be 98426 VAC if read with an RMS meter, or 50-65 VAC if read with a non RMS meter. This voltage will be applied only when there is an attempt to ignite the burner or when the ignition control's flame sensingsystem has determined that it is OK to allow burner operation. Even if voltage has been confirmed at the end of the safety circuit, the "trial for ignition" sequence is imposed by the ignition control. This sequence consists of a 15 second period of pre -purge, a 40 second period for heat -up of the igniter and a 7 second trial for ignition. During this last 47 seconds there is voltage'between test point H and test point 1. If satisfactory ignition is not achieved, the igniter is turned off and the system waits for a 15 second inter-purgeperiod. The.system may go through this cycle as many as three times, but thereafter it is "locked out" by the ignition control. Additional at- tempts will be made only if the call for heat is inter- rupted'by turning off electrical power or setting the control to "Off ' and then back to "Pool" or "Spa". LX and LT Low NOxA.S.M.E. Pool/Spa Heater Page43 To trouble shoot the ignition control's igniter circuit, connect the voltmeter leads at test points H and I, and set the control to call for heat. Observe that the normal ignition sequence takes place. After the 15 second pre -purge, note the voltage between test points H and I. Then look for the glow of the igniter through the view port on the front of the combustion, chamber. If the correct voltage is detected between points H and -I during the trial for ignition but the igniter does not. glow, check the connections to the igniter. Check the igniter with the ohmmeter. Disconnect the igniter wires at the quick disconnects. Place one lead of the meter on each wire of the igniter. The resistance should read between 40 and 75 Ohms at ambient air temperature. If the meter reads outside of this range or shows an open or.short circuit, replace, the igniter. If voltage does not appear between points H and I during the trial for -ignition, there may be a bad connection or a. short on the power distribution board or the ignition control. Check all connections on the power distribution board and the ignition control for loose or *corroded connections before continuing with this checkout procedure. If your heater is connected to a 230 VAC supply, perform the following procedure. If your heater is connected to a 115 VAC supply, skip to the paragraph indicated with bold type. Place the black lead of the meter in contact with the pin on the power distribution board that is labeled "ACH" (test point Q. Place the red lead of the meter in contact with the pin on the power distribution board thatis labeled "L1" where the black wire is connected (test point J). The meter should read 1.96-253 VAC. If the meter shows voltage outside of this range, the power distribution circuit board has a loose connection or has shorted. Check the connections or replace the board. If the meter shows voltage within the range above, then move the red lead to the "L I" connection on the ignition control (test point K). Incorrect voltage here means that the wire between the power distribution board and the "L1 " connection on theignitioncontrol is faulty. Check the connections or replace the power distribution .board. Voltage at testpoint K.shows that voltage is getting to the ignition control. Now move the red meter lead to the "IGN 240" connection on the ignition control (test point L). No voltage -at this location during the trial for ignition means that the ignition control has failed and needs replacement. If the ignition control is working properly, it will have stepped the voltage down to 98-126 Volts RMS (50-65 Volts non RMS) for use by the igniter. If the correct voltage is shown, then place the red lead of the meter in contact with the pin on the power distribution board that is labeled 1/240" where the, white wire with the black trace is connected (test point M). No voltage means that.the wire between the power distribution board and the "IGN 240`connection on the ignition control is faulty. Check the connections or replace the power distribution board. If the correct voltage is detected, place the black lead of the meter in contact with the pin on the power distribution board that is labeled "ACN" where the red wire is connected (test point B). Place the red lead of the meter in contact with the pin on the power distribution .board that is labeled "U" where the red wire is connected (test point N). No voltage at this point means that the power distribution circuit board has shorted and needs to be replaced. If the voltage is correct, move the red lead to the connection at the igniter wire quick disconnect (test point H). No voltage means that the wire be- tween the power distribution board and the igniter test point H is faulty. Check the connections or replace the power distribution board. Place the red lead of the meter in contact with the pin on the power distribution board that is labeled "IGN" where the red wire is connected (test point P). The meter should show 196- 253 Volts when the control is not energizing the igniter or 169-219 Volts RMS (147-192 non RMS) when the control is energizing the igniter. If the voltage mea- sured is not within the range specified for the above conditions, then the power distribution board is shorted or open. Replace this component. If the correct voltage is measured at this point, move the red meter lead to the igniter wire quick disconnect (test point I). If the correct voltage as measured at test point P does not show here, the: wire between the power distribution board and the igniter test point I is faulty. Check the connections or replace the power distribution board. If your heater is connected to a 115 VAC supply, perform the following procedure. Place the black lead of the meter in contact with the pin on the power distribution board that is labeled "ACH" (test point Q. Place the red lead of the meter in contact with the pin on the power distribution board that is labeled "L1" where the black wire is connected (test point J). The meter should read 98-126 VAC. If the meter shows voltageoutside of this range, the power distribution circuit board has a .loose connection or has shorted. Check the connections or replace the board. If the metershows-voltagewithin the range above, then move the red lead to the "L1" connection on the ignition control (test point K): Incorrect voltage here means that the wire between the power distribu- tion board and the "L1"connection on the ignition control is faulty. Check the connections or replace the power distribution board. 98-126 Volts at test point K shows that voltage is getting to the ignition control. Now move the red meter lead to the "IGN 120" connection on the ignition control (test point Q). No voltage at this location during the trial for ignition means that the ignition control has failed and needs replacement. If the ignition control is working properly, it will pass the voltage, 98-126 Volts, for use by the (Continued on page 46) Page 44 :BK ------ }W----_.---------------- - 150°F LIMIT SWITCH MBK 1 35O LIMIT SWITCH W - - -W-- W --- MANUAL RESET FUSIBLE HIGH LIMIT SWITCH 0 LINK BLOWER N CAPACITOR GND BLOWER / 1 SCREW BR i' • O r U120 Q/BLOWER o D IGN PRESSURE /U E o SWITCH • p Ll •_ R G F1 R FUSE G c o GROUND BK • SCREW W/Y €f wy- R.

Place the red lead of the meter in contact with the pin on the power distribution board that is labeled "IGN" where the red wire is connected (test point P). The meter,should show 98- 1.26 Volts when the control is not energizing the igniter or zero volts when the control is energizing the igniter. Ifit does not, then the power distribution circuit board is shorted or open. Replace this component. If thecorrect voltage is measured at this point, move the red meter lead to the igniter wire quick disconnect (test point 1).
