figuration. Check your state or
local codes.
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 quali-
fied chimney cleaner. Creosote
will ignite if highly heated. A dirty
chimney flue may create and dis-
tribute soot within the house. In-
spect chimney flue and firebox
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 fire-
place. If not, drafting may cause
pilot outage or sooting. Use a
heat-resistant sealant. Do not
seal chimney flue damper.

less installed as a vented ap-
pliance (Variable Manually-

INSTALLATION
Continued
CAUTION: This heater cre-
ates warm air currents. These
currents move heat to wall sur-
faces next to heater. Installing
heater next to vinyl or cloth wall
coverings or operating heater
where impurities (such as, but
not limited to, tobacco smoke,
aromatic candles, cleaning flu-
ids, 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 5.

pane/LP) for your unit. If your gas supply is not
correct, do not install heater. Call dealer where
you bought heater for proper type heater.
WARNING: This appliance is
equipped for (natural or propane/
LP) gas. Field conversion is not
permitted.
