INSTALLATION
NOTICE: This heater is intended for use as supple-
mental heat. Use this heater along with your primary
heating system. Do not install this heater as your
primary heat source. If you have a central heating
system, you may run system’s circulating blower
while using heater. This will help circulate the heat
throughout the house. In the event of a power outage,
you can use this heater as your primary heat source.
WARNING: A qualified service person must install
heater. Follow all local codes.
NOTICE: State or local codes may only allow operation
of this appliance in a vented configuration. Check your
state or local codes.
WARNING: If optional remote control is used, make
sure the selector switch is in the OFF position before
installing heater.
WARNING: Before installing in a solid fuel burn-
ing fireplace, the chimney flue and firebox must be
cleaned of soot, creosote, ashes and loose paint by
a qualified chimney cleaner. Creosote will ignite if
highly heated. A dirty chimney flue and firebox may
create and distribute soot within the house. Inspect
chimney flue for damage. If damaged, repair flue
before operating heater.
WARNING: Seal any fresh air vents or ash clean-
out doors located on floor or wall of fireplace. If not,
drafting may cause pilot outage or sooting. Use a heat-
resistant sealant. Do not seal chimney flue damper.
CAUTION: This heater creates warm air currents.
These currents move heat to wall surfaces next to
heater. Installing heater next to vinyl or cloth wall cov-
erings or operating heater where impurities (such as,
but not limited to, tobacco smoke, aromatic candles,
cleaning fluids, oil or kerosene lamps, etc.) in the air
exist, may discolor walls or cause odors.
