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 heatthroughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.
NOTICE: A qualified service per-
son must install heater. Follow
all local codes.
NOTICE: State or local codes may
only allow operation of this appli-
ance in a vented configuration.
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 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
chimney flue damper.

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
• in high traffic areas
• in windy or drafty areas
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 to-
bacco 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.
