INSTALLATION

NOTICE: This heater is intended
for use as supplemental heat. Use
this heater along with your pri-
mary heating system. Do not in-
stall 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 circu-
late the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
NOTICE: State or local codes may
only allow operation of this appli-
ance in a vented configuration.
Check your state or local codes.
WARNING: A qualified ser-
vice person must install heater.
Follow all local codes.
WARNING: Make sure the se-
lector switch is in the OFF posi-
tion before installing heater.
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 for damage. If
damaged, operate heater with flue
damper closed.
WARNING: Seal any fresh air
vents or ash clean-out doors lo-
cated on floor or wall of fireplace.
If not, drafting may cause pilot
outage or sooting. Use a heat-
resistant sealant. Do not seal

WARNING: Never install the
heater
• in a bedroom or bathroom un-
less installed as a vented ap-
pliance, see page 10.
• in a recreational vehicle
• where curtains, furniture,
clothing, or other flammable
objects are less than 42 inches
from the front, top, or sides of
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 tobacco smoke, aromatic
candles, cleaning fluids, oil or
kerosene lamps, etc.) in the air
exist, may discolor walls.
IMPORTANT: Vent-free heaters add mois-
ture 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 Com-
bustion and Ventilation, pages 4 through 6.

CHECK GAS TYPE

Use only natural gas. If your gas supply is not
natural gas, do not install heater. Call dealer
where you bought heater for proper type heater.
