UNVENTED PROPANE GAS LOG HEATER
INSTALLATION
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. 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 8
• in a recreational vehicle
• where curtains, furniture,
clothing, or other flammable
objects are less than 36 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 in the air (such
as tobacco smoke) 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 and 5.

CHECK GAS TYPE

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