Warner Avenue Suite A Santa Ana California 92705 DATE: February 17, 1994 PH 714-261-5704 FAX 714-852-8641 To: Attn: Reference: Dear Enclosed are calculations and backup data that demonstrate compliance with codes for alternate dryer duct systems. Background The 1991 Uniform Mechanical Code (UMC) Section 1903(b) limits dryer vents to 14 feet of 4" duct with two elbows. In addition, UMC Section 105 allows the building official to approve alternatives to the code as long as equivalence can be demonstrated. (Copies of these code sections are included In Appendix 3 of this package.) ICBG, In the May -June 1990 issued of Building Standards Magazine Question -Answer Section, provided an Interpretation that allows methods such as ASHRAE Chapter 32 Fundamentals to be acceptable in showing equivalency with UMC Code (copy in Appendix 4 of this package). Calculations Our approach is to calculate the resistance to air flow of the dryer duct system prescribed In UMC 19903(b) and compare it to the calculated resistance for an alternate system. ASHRAE 1989 Fundamentals Chapter 32 Is used as the basis of the calculations. Appendices 1 and 2 list the applicable equations and data use in the calculations. The code system is listed in the analysis as "A. Allowable Losses -Base Case". Alternate systems are shown below. Both the base and alternate systems are calculated at an air flow of 150 cubic feet per minute (CFM). The actual value varies from manufacturer to manufacturer, but tends to be in that range. Note that for the purpose of this analysis, the value used is not important. It is imperative that the same value Is used for both the base and alternate calculations. The number at the bottom of the column labeled W" represents the system resistance. If the value shown for the alternate system is less than or equal to the base system, compliance with code Is established. Conclusion Calculations contained in this package demonstrate that the alternate duct systems are equivalent to the requirements of UMC 1903(b). Please contact me if any clarifications or additional material is needed. Very truly yours, ��%ls�Vrr Samu .

Are the 14 feet and two 9o -degree elbows mentioned in Section 1903 (b) a fir ed limitation on clothes dryer moisture exhaust systems or can the equivalent length and number of fittings be changed as one might do in calculatingduct sizing and resistance? A<American National Standards institute Standard III 221.5.1 Identified in the Reference Standards section in Appendix C requires that gas-fired domestic clothes dryers be tested with an exhaust duct equal in length to the maximum length specified in the manufacturer's installation instructions, but not less than 14 feet of duct plus two 90 -degree elbows. Some manufacturers of dryers recommend longer duct lengths or a greater number of fittings- However; these appliances create a dilemma for the building official because: 1. The dodms dryer is frcquendy not installed until after final inspection of the dryer venting system; or 2. Ahorneownerfoecupantmayswitchappliances %ithoutnoti- . tying the building department - Fortunately, domestic clothes dryers have a temperature limit switch in the exhaust airstream in addition to a temperature selector switch. Thus, probably the worst failure. mode for a dryerwith a low ability to move air.through s moisture exhaust system will be an extended drying cycle and a higher -than -normal rate of lint accu- mulation because of the lower air velocity through the exhaust An equivalent length may be used. The Air Conditioning Con- tractors Association Manual on duct design and Chapter 32 of the American Society of Heating, Refrigerating and Air -Conditioning Engineers Fundamentals Handbook provides methodologies for sizing ducts to develop a specified static pressure drop.

Ooes Section 79.902 (e) prohibit the dispensing of Class land Class ii flammable and combustible liquids from aboveground tanks at private fueling facilities such as truck depots, motor pools, etc. t A , Yes. Section 9.121 defines a "service station, automo- tine" as follows: that portion of property where flammable or combustible liquids or gases used as motor fuels are stored and.dispensed from fixed equipment into the fuel tanks of motor vehicles and shall include the.sale and service oftires, batteries and acces- sories and minor automotive maintenance work. There are no provisions within the definition of an automotive service station which suggest that the treatment of a fueling opera- tion would be different for a public versus a private type of opera- tion.' Section 79.902 (e) provides criteria for the safe dispensing of flammable and combustible liquids at service stations. The particu- lar limitation on storage tanks in the last sentence dates back to before the inception of the Uniform Fire Code. Section 79.902 (b) is (he section that originally contained these criteria (note that this section also regulates storage of Class Ill -A liquids). The limitation in Section 79.902 (e) was only recently added to place additional emphasis on the requirements. The only exceptions to the provi- sions in Section 79:902 (e) are for tanks installed in special enclo- sures:as described in Section 79.902 (e) and for tanks installed for private use on farms and rural areas and at construction sites, earth- moving projects, gravel pits or borrow pits when in accordance with Section 79.1001 _ In the early 1900s, it was common practice to dispense fuel from aboveground tanks. These operations experienced a poor fire his- tory which eventually resulted in fire codes requiring underground tanks. Underground installation' reduces fire risk by protecting tanks from exposure to lightning, impact and adjacent fire. Although the requirements imposed by the Environmental Pro- tection Agency. and many states mandate corrosion protection, leak detection and financial responsibility forunderground storage tanks, the increased cost of meeting these additional obligations has not been sufficiently demonstrated to the Uniform Fire Code voting membership to outweigh the concern for safety promp:ed by allowing aboveground tanks for fuel dispensing. Provisions regulating --et vice stations will be revised in the 1991 edition of the Fire Code. Effective in the 1990 Accumulative Sup- plement, the definition of "service station, automotive" has been revised by deleting the words "and shall include the sale and service of tires, batteries and accessories and minor automotive maintenance work." Also, to further clarify the definition. them ter "service station" has been replaced by •'motor vehicle fuel. dispensing station." These changes help clarify that the term "Ser- vice station" applies when a fuel -dispensing operation is present. An appendix proposed for the 1991 edition includes recorn- mended regulations for allowing various configura:ions o(above- ground tanks at service stations. The proposal is schedlrled fcr final vote at the WFCA Annual Meeting In August and Is twni 96 in Part 111 of the March -April, 1990, budding cu?tj. tine. ` it BUIlo1NC ST,, _ ::IRbs / MJ✓•Ju nC. 1990 /64-1 '.�.lt := -.
