First find the cubic feet of area to be heated length x width x height. NOTE: Include any 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.   STEP 2. Divide area cubic feet by 50. EXAMPLE: 2,812.5 ) 50 = 56.25. Multiply this number by 1,000 for total Btu input   room can support. E XAMPLE: 56.25 x 1,000 = 56,250 Btu.   STEP 3. List all gas burning appliances in this area and total the combined Btu input. EXAMPLE:   Cozy vent free heater……………………..   Gaswaterheater…………………………..   Gas range (all burners & oven on)………..   20,000 Btu   58,000 Btu   28,000 Btu   106,000 Btu   Page 4   Download from Www.Somanuals.com. All Manuals Search And Download.   FRESH AIR FOR COMBUSTION, VENTILATION AND HEAT DISTRIBUTION - CONT’D.   STEP 4. Compare the total Btu the area can support (from Step 2) to the total Btu in the area the heater will be installed   (from Step 3). If the total from Step 2 is larger this is considered an unconfined space, if Btu total from Step 3 is larger this   is considered a confined space and provisions must be made for additional 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 (6x10-11 Kg   per pa-sec-m²) 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 frames, between sole   plates and floors, between wall ceiling joints, between wall panels, at penetration for plumbing, 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.

If you have trouble lighting the pilot or   keeping it lit, it may mean that this safety device   is warning you that there is a problem with your   system. Inspection and repairs or replacement   must be made by a trained gas service   technician.   • • If you cannot reach your gas supplier,   call the fire department.   Installation and service must be performed   by a qualified installer, service agency or the   gas supplier.   Do not store or use gasoline or other   flammable vapors and liquids in the vicinity   of this or any other appliance.   TAMPERING IS DANGEROUS   The pilot safety system may also not work if you   do not follow the lighting instructions carefully   or if you tamper with the gas control that you   use to light the pilot. Tampering with the gas   control, particularly with tools, can damage the   safety mechanism in the control and can allow   gas to leak. This can result in a fire or   explosion causing property damage, personal   injury or death.   CRITICAL SAFETY POINTS TO   REMEMBER . . .   • Your gas has been odorized so that you   can smell it. Always smell around for   gas before lighting your appliance.   Sniff for L.P.-gas at floor level. LP-gas is   heavier than air and may temporarily   exist at floor level.   • IF YOU SMELL GAS, DON’T LIGHT IT   • • If you smell gas, do not attempt to light   the pilot. Do not cause a spark by   turning on or off electrical switches or   appliances or by using the phone. Turn   off the gas to the appliances and call your   gas supplier from another location.   If your gas control has gotten wet as the   result of flooding or other wetting, it   must be replaced immediately by a   trained gas service technician. Water   can lead to damage of the internal safety   mechanism in the gas control and can   create a hazardous condition.   IF YOU CAN’T LIGHT IT, DON’T FIGHT IT!   THIS IS NOT AN ADVERTISEMENT   Download from Www.Somanuals.com.
