September 30 , 1992 Mr. James Papillon ). l C Plumbing Inspector City of Northampton Northampton, MA 01060 rei. 2 ,92 «..� Re: Hampton Gardens ; 35 Dear Mr. Papillon: Hampton Gardens is a 207 unit apartment community with wood- framed construction covered with a brick veneer. These units are on slab construction with pitched roofs . All units have individ- ual gas-fired, forced warm air furnaces; domestic hot water and cook ranges. The furnaces are located in the living area in a separate heater room, which are vented top and bottom to the living room and kitchen area. The domestic hot water heater is located in an adjacent closet. The general classification as defined by the 1992 Mass . State Gas Code would be "unconfined space" (Sec. 1 . 7 definition) 53 . 3 (a) equipment located in confined space and Figure #1 . The 40-1 bedroom units are two story garden apartments grouped in units of four back-to-back with individual front entrances. The 2 , 3 and 4 bedroom units are townhouse units in groups of two back-to-back. The windows are architectural steel, 5 feet high with 2 or 3 sliding units varying in width from 3 feet to 9 feet. The 2 , 3 and 4 bedroom units have a total load of 170 ,000 BTU/hr. and volume varying . from 6 , 400 cu . ft. to 10 , 400 cu . ft. are in compliance with the ' 92 codes, Sec. 5 . 3 . 3 . , "equipment located in confined spaces, (a) all air from inside the building" . The present 1 bedroom apartments will need modifications or a decrease in BTU input to comply. As these apartments are back- to-back garden units, the lower units have only 3 exposed walls; on slab construction; no ceiling loss; (second floor units above) , the 80 ,000 BTU/hr. furnaces are at least 50% over-sized. The second floor furnaces are approximately 50% over-sized, too; following the installation of 6 inches of cellulose insulation over the original 2} inch batting. By changing the spuds (orifices) in the burners of the furnaces, the manufacturer confirms the BTU input can be reduced from 80 ,000 to 60 ,000 without any reduction in efficiency or undesir- able side effects. In fact, I believe the apartment temperature E p.T cel err rrer'!`•: r • S Papillon Letter page 2 will be more even because the heat will be supplied at a lower temperature with a longer cycle rather than in hot short blasts . With this reduction the total load will be 130 ,000 BTU/hr. The 1 BR apt. volume is 740 sq. ft. x 8 ft. high = 5 ,920 cu. ft. 5920 = 45 .5 cu. ft. /1 , 000 BTU input 130 The ' 92 code recommends 50 cu. ft. /1 ,000 BTU input. We will have 45 .5 =91% of ' 92 recommendation 50 The layout of the one bedroom apartment is a large open area with the kitchen, dining area and living room without doors. The living room has a 5 ft. high x 10 ft. wide 3-panel sliding window. The large bedroom has an undercut door and two 5 ft. high, 2-panel siding windows . The apartment has front to back cross ventilation. For 20 years the present 80 ,000 BTU/hr. furnaces, hot water tanks, and gas ranges with a combined input of 150 ,000 BTU/hr. have performed without any indications of insufficient combustion air. The reduction in furnace input gives an added increment of safety. It is my opinion there is sufficient infiltration to more than meet the needs of the installed gas load and residents of Hampton Gardens .

ON GARDENS FAX 2/18/93 DEFT OF BUILDINGII�J;;'F ;TIjPJS Dear King: My understanding of this request, to derate the furnace inputs, is to meet the minimum combustion air requirements set forth by the local code authorities. As in ail installations, the manufacturers instructions, national codes, or local codes, which ever is more stringent, determines the installation requirements. The local authority has final say on whether a certain requirement is sufficient or unnecessary. As Mr. Hughes pointed out in his letter of February 1, 1993, the requirement of 50 cu. ft. per 1000 BTU total combined input, did not exist at the time these furnaces were installed. If the local authority is requiring these units to be brought up to the current code, derating of the furnaces is not an acceptable means. The current Fuel Gas Code requires the unconfined space to be "not less than 50 cubic feet per 1000 BTtJ per hour of aggregate input ra in of -all appliances installed in that space." This volume is to be deters,tined by rating plate •information, not actual measured input. Also, the volume that Mr. Larsen used to base his • •calculation is incorrect, based on the current code. The current code does not allow the addition of space (the bedroom) to the total volume if separated with a door, even when undercut. The furnaces in question could have their inputs reduced by changing orifice spuds as is done for applications at high altitudes, but a reduction of the proposed 25% could create problems. The ability of the furnace to maintain the proper heat rise across the heat exchangers is unlikely. Too much air would cause a loss of personal comfort and possibly cause condensation of flue products inside of the heat exchanger. Since the furnaces in question have operated satisfactorily for twenty (20) years at full rate, I would not recommend this course of action. As Mr. Larsen pointed out, when the current furnaces are replaced they could and should be replaced with units more nearly matching the actual heat loss of the structure. Regards, (p.e42/1.
