OWNER’S MANUAL

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.

WARNING: A qualified ser- vice person 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: Make sure the selector switch is in the OFF po- sition before installing heater.

WARNING: Before installing in a solid fuel burning fireplace, the chimney flue and firebox must be cleaned of soot, creo- sote, ashes and loose paint by a qualified chimney cleaner. Creo- sote will ignite if highly heated. A dirty chimney flue may create and distribute soot within the house. Inspect chimney flue for damage. If damaged, operate

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.
