IMPORTANT INFORMATION
WARNING: This appliance assembly contains burner orifices specifically for the input gas and
Btu rating. Modifying or failure to use the factory orifice may cause property damage, personal
injury or loss of life.
1. Do not use a natural gas set for propane or a propane set for natural gas.
2. There a many different local codes for gas appliances. The installation and the provision for combustion and
ventilation air must conform to local codes and, or in the absence of local codes, with the National Fuel Gas Code
ANSI Z223.1 – (most current revision).
3. Gas appliances must be installed by personnel qualified for installing gas appliances.
4. This appliance must be installed only in a solid-fuel burning fireplace with a working flue and constructed of
noncombustible materials. Solid fuels are not to be burned in a fireplace where a decorative appliance has been
installed.
5. A permanent free opening must be provided by either the fireplace chimney or chimney damper to vent flue gasses.
Any chimney damper must be fixed in a manner, which will maintain the permanent free opening at all times. Use
Table II to determine the minimum permanent free opening based on chimney height and the appliance Btu input
rating. Refer to the Damper Stop section for additional directions.
6. The minimum free opening is based only on two factors; chimney height and Btu input rating. Many other factors affect
the fireplace drafting. It is the homeowner’s responsibility to assure their fireplace has adequate draft. If fumes or soot
from the gas burning are evident in the room when the damper is fully open, it indicates that the fireplace draft is
defective. Do not operate your gas appliance until the fireplace draft is corrected. Consult your fireplace specialist.
7. A fireplace screen must be in place when the appliance is operating and, unless other provisions for combustion air are
provided, the screen shall have an opening(s) for introduction of combustion air.
8. When glass fireplace doors are used, always operate your gas appliance with the doors fully open to allow for proper
combustion air and to keep control valves from overheating.
9. The minimum inlet supply pressure for the purpose of input adjustment is 5.0 inches (natural gas) 11 inches (propane
gas) in water column. The maximum inlet supply pressure is 10.5 inches (natural gas) 13 inches (propane gas) in
water column.
10. The appliance and its individual shut-off valve must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2 psig (3.5kPa). The appliance must be isolated from
the gas supply piping system by closing its individual manual valve during pressure testing equal to or less than 1/2
psig (3.5kPa).
11. The fireplace chimney or venting system should be examined annually and cleaned as required by a qualified agency.
