INSTALLATION

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 pri- mary 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: Installation and repair should be done by a qualified service person. The appliance should be inspected before use and at least annu- ally by a professional service person. More frequent cleaning may be required due to exces- sive lint from carpeting, bedding material, etc. It is imperative that control compartments, burners and circulating air passageways of the appliance be kept clean.

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. Creosote will ignite if highly heated. A dirty chimney flue may create and distribute soot within the house. Inspect chim- ney flue and firebox for damage. If damaged, repair flue before operating heater.

WARNING: Seal any fresh air vents or ash clean-out doors located on floor or wall of fire- place. If not, drafting may cause pilot outage or sooting. Use a heat-resistant sealant. Do not seal chimney flue damper.

•in a bedroom or bathroom

•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 firebox opening

•in high traffic 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, but not limited to, tobacco smoke, aromatic candles, cleaning flu- ids, 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 ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, page 5.
