doorless passageways or ventilation grills between the rooms.
1. Determine the volume of the space Length × Width × Height = cu. ft. (volume of space)
Example: Space size 20 ft. (length) × 16 ft.(width) × 8 ft. (ceiling height) = 2560 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 cu. ft. to determine the maximum BTU/hr the space can support.
_______ (volume of space) ÷ 50 cu. ft.= (Maximum BTU/hr the space can support)
Example: 2560 cu. ft. (volume of space) ÷ 50 cu. ft. = 51.2 or 51,200 (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 Example:
Gas heater logs __________BTU/hr Gas water heater 30,000 BTU/hr
Other gas appliances*+ ____BTU/hr Vent-free heater + 26,000 BTU/hr
Total = ____BTU/hr Total = 56,000 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).

CAUTION: Never connect heater directly to the gas supply. This heater requires an external
regulator (not supplied). The external regulator between the gas supply and heater must be installed.
Gas supplier provides external regulator for natural gas.
WARNING: Never connect heater to private (non-utility) gas wells. This gas is commonly known
as wellhead gas.
The installer must supply an external regulator for liquid propane. The external regulator is
provided by the gas supplier for natural gas. The external regulator will reduce incoming gas pres-
sure. You must reduce incoming gas pressure to between 11 and 14 in. of water column for propane
and between 6 and 14 in. of water column for natural gas. If you do not reduce incoming gas pres-
sure, heater regulator damage could occur. Install external regulator with the vent pointing down as
shown in Fig. 6. Pointing the vent down protects it from freezing rain or sleet.
