INSTALLATION
Continued
WARNING: Before installing in
a solid fuel burning fireplace, the
chimney flue and firebox must be
cleaned of soot, creosote, ashes
and loose paint by a qualified chim-
ney cleaner. Creosote will ignite
if highly heated. A dirty chimney
flue may create and distribute soot
within the house. Inspect chimney
and firebox flue for damage. If dam-
aged, repair flue and firebox before
operating heater.
WARNING: Seal any fresh
air vents or ash clean-out doors
located on floor or wall of fire-
place. If not, drafting may cause
pilot outage or sooting. Use a
heat-resistant sealant. Do not
seal chimney flue damper.
WARNING: Never install the
heater

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 coverings or
operating heater where impurities
(such as, but not limited to, to-
bacco smoke, aromatic candles,
cleaning fluids, oil or kerosene
lamps, etc.) in the air exist, may
discolor walls or cause odors.
IMPORTANT: Vent-free heaters add moisture to
the air. Although this is beneficial, installing heater
in rooms without enough ventilation air may cause
mildew to form from too much moisture. See Air
for Combustion and Ventilation, page 6.

for your unit. If your gas supply is not correct, do
