INSTALLATION

NOTICE: This heater is intended for use as supple- mental 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 system’s circulating blower while using heater. This will help circulate 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 service person must in- stall heater. Follow all local codes.

NOTICE: State or local codes may only allow opera- tion of this appliance in a vented configuration. Check your state or local codes.

WARNING: Before installing in a solid fuel burn- ing fireplace, the chimney flue and firebox must be cleaned of soot, creosote, ashes, and loose paint by a qualified chimney cleaner. Creosote will ignite if highly heated. A dirty chimney flue may create and distribute soot within the house. Inspect chimney flue and firebox for damage. If damaged, operate heater with flue damper closed.

WARNING: Seal any fresh air vents or ash clean- out doors located 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 unless installed as a vented appliance (Variable Manually-Controlled Models Only) (see page 10)

•in a recreational vehicle

•where curtains, furniture, clothing, or other flam- mable 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 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, but not limited to, tobacco smoke, aromatic candles, cleaning fluids, oil or kerosene lamps, etc) in the air exist, may discolor walls or cause odors.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough venti- lation air may cause mildew to form from too much moisture. See Air for Combustion 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.
