Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms. 1. Determine the volume of the space (length x width x height). Length x Width x Height = ___________________ cu. ft. (volume of space) Example: Space size 18 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2304 cu. ft. (volume of space) If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space. 2. Divide the space volume by 50 cubic feet to determine the maximum BTU/Hr the space can support. ____________ (volume of space) . 50 cu. ft. = (Maximum BTU/Hr the space can support) Example: 2304 cu. ft. (volume of space) . 50 cu. ft. = 46.1 or 46,100 (maximum BTU/Hr the space can support) 3. Add the BTU/Hr of all fuel burning appliances in the space. Vent-free heater ___________________ BTU/Hr Gas water heater* ___________________ BTU/Hr Gas furnace ___________________ BTU/Hr Vented gas heater ___________________ BTU/Hr Gas fireplace logs ___________________ BTU/Hr Other gas appliances* + ___________________ BTU/Hr Total = ___________________ BTU/Hr Example: Gas water heater 40,000 BTU/Hr Vent-free heater + 10,000 BTU/Hr Total = 50,000 BTU/Hr * Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors. 4. Compare the maximum BTU/Hr the space can support with the actual amount of BTU/ Hr used. _________________ BTU/Hr (maximum the space can support) _________________ BTU/Hr (actual amount of BTU/Hr used) Example: 46,100 BTU/Hr (maximum the space can support) 50,000 BTU/Hr (actual amount of BTU/Hr used) The space in the above example is a confined space because the actual BTU/Hr used is more than the maximum BTU/Hr the space can support. You must provide additional fresh air. Your options are as follows: A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 7. B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8. C. Install a lower BTU/Hr heater, if lower BTU/Hr size makes room unconfined. If the actual BTU/Hr used is less than the maximum BTU/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation. WARNING You must provide additional ventilation air in a confined space. 6 FRESH AIR FOR COMBUSTION AND VENTILATION Continued VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). WARNING Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces. Figure 2 - Ventilation Air from Inside Building Or Remove Door into Adjoining Room, Option 3 Ventilation Grills Into Adjoining Room, Option 2 12" 12" Ventilation Grills into Adjoining Room, Option 1 Continued 7 FRESH AIR FOR COMBUSTION AND VENTILATION Continued VENTILATION AIR (Continued) Ventilation Air From Outdoors Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation for required size of ventilation grills or ducts. IMPORTANT: Do not provide openings for inlet or outlet air into attic if attic has a thermostat-controlled power vent. Heated air entering the attic will activate the power vent.

Follow all local codes. CHECK GAS TYPE Use only propane gas. If your gas supply is not propane, do not install heater. Call dealer where you bought heater for proper type heater. INSTALLATION ITEMS Before installing heater, make sure you have the items listed below. • external regulator (supplied by • ground joint union installer, see page 13) • test gauge connection * (see • piping (check local codes) Figure 13, page 14) • sealant (resistant to propane gas) • sediment trap • manual shutoff valve * • tee joint • pipe wrench * An A.G.A. design-certified manual shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge conne...
