FRESH AIR FOR COMBUSTION , VENTILATION AND HEAT DISTRIBUTION With todays eneigy efficient homes , it is possible to make your home so air tight that it can result in stale air , dry rot , mold development and host of other related problems . Gas burning appliances need fresh air for combustion as welt as for good distribution of heated air throughout the home . The l \ _ ltowing guide provides good general roles for classifying and properly ventilating most homes . The National Fuel Gas Code ANSI Z223 . 1 defines a confined space as " a space whose volume is less than 50 cubic feet per 1,000 Btu per hour ( 4.81n3per Kw ) of the aggregate input rating ofatt appliances installed in that space and an unconfined space as a space whose volume is equal to or greater than 50 cubic feet per 1,000 Btu per hour ( 4.8m 3per Kw ) of the aggregate input rating of all appliances installed in that space . Rooms comlnunicating directly with the space in which the appliance is installed , through openings not furnished with doors , are considered a part of the unconfined space . " " This heater shall not be installed in a confined space or unusually tight construction unless provisions for adequate combustion and ventilation air are made . Use the l \ _ llowing example to determine if the heater is being installed in a confined or unconfined space . " STEP 1 . First find the cubic feet of area to be heated lenath x width x heiaht . NOTE : Include aW adjoining rooms that cannot be separated by closing a door or that have a air exchange grille that cannot be closed between rooms . EXAMPLE : Area size 25 ft . x 15 ft . x 7 - 1 / 2 ft . 2,812.5 cubic feet . STEP2 . Divide area cubic feet by 50 . EXAMPLE : 2,812.5 50 56.25 . Multiplythisnumberby 1,000 for total Btu input room can support . E XAMPLE : 56.25 x 1,000 56,250 Bin . STEP3 . List all gas burning appliances in this area and total the combined Btu input .

FRESH AIR FOR COMBUSTION , VENTILATION AND HEAT DISTRIBUTION - CONTD . STEP 4 . Compare the total Btu the area can support ( from Step 2 ) to the total Btu in the area the heater wilt be installed ( fioln Step 3 ) . If the total froln Step 2 is larger this is considered an unconfined space , ifBtu total froln Step 3 is larger this is considered a confined space and provisions must be made t \ _ radditional combustion and ventilation air . EXAMPLE : Btu area can support is 56,250 , total Btu in area is 106,000 this would be a confined space . NOTE : A third construction class is one with unusually tight construction , defined as , construction where : ( A ) Walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of 1 per ( 6x 10 - 11 Kg per pa - sec - ln 2 ) or less with openings gasketed or sealed , and , ( B ) Weatherstripping has been added enable windows and doors , and , ( C ) Caulking or sealants are applied to areas such as joints around window and door fialnes , between sole plates and floors , between wall ceiling joints , between wall panels , at penetration t \ _ rplumbing , electrical , and gas lines , and at other openings . " WARNING : If the area in which the heater may be operated is smaller than that defined as an unconfined space , or if the building is of unusually tight construction , provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code , ANSI Z223 . 1 , Section 5.3 or applicable local codes . " Examples would be to provide two permanent openings either to an adjoining room , or to the outside . See the National Fuel Gas Code for details .
