MINIMUM NONCOMBUSTIBLE MATERIAL CLEARANCE
If Not Using Mantel
You must have noncombustible material(s) above the replace
opening. Noncombustible materials (such as slate, marble, tile,
etc.) must be at least 1/2 inch thick. With sheet metal, you must
have noncombustible material behind it, such as a noncombustible
replace hood accessory. See Figure 4 next page for minimum clearance requirements.
NOTICE: This heater may be used as a vented product. If so, you must always operate log set with
chimney ue damper open. If running log set with damper open, noncombustible material above replace
opening is not needed. Go to Installing Damper Clamp Accessory for Vented Operation, page 11.
WARNING: Maintain the minimum clearances.
If possible, provide greater clearances from the
oor, ceiling, and adjoining wall than required.

WARNING: Seal any fresh air vents or ash clean-out doors located on the oor or wall of replace to prevent
drafting caused by pilot outage or sooting. Use a heat-resistant sealant. Do not seal chimney ue damper.
CAUTION: This heater creates warm air currents. These currents move heat to wall surface next to heater. In-
stalling heater next to vinyl or cloth wall coverings or operating heater where impurities (such as tobacco smoke,
aromatic candles, cleaning uids, oil or kerosene lamps, etc.) in the air exist may discolor walls.
NOTICE: State or local codes may only allow operation of this appliance in a vented conguration. Check your
state or local codes.
NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating
system. Do not install this heater as your primary heat source. If you have a central heating system you may run
the system’s circulating blower while using the heater. This will help circulate the heat throughout the house. In
the event of power outage, you can use this heater as your primary heat source.
IMPORTANT: Vent-free heaters add moisture to the air. Although this is benecial, installing heater in rooms
without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and
Ventilation, pages 5 through 7.
WARNING: This appliance is designed for installation in only a solid-fuel burning masonry or UL 127 factory-built
replace or in a listed ventless rebox enclosure. Exception: DO NOT install this appliance in a factory-built re-
place that includes instructions stating it has not been tested or should not be used with unvented gas logs.

WARNING: Before installing in a solid ue burning rebox, the chimney ue and rebox must be cleaned of
soot, creosote, ashes and loose paint by a qualied chimney cleaner. Creosote will ignite if highly heated. A dirty
chimney ue may create and distribute soot within the house. Inspect chimney ue for damage.
