OWNERS 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: 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. A dirty chimney flue may create and dis- tribute soot within the house. In- spect chimney flue for damage. If damaged, operate heater with flue

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 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 tobacco 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.

CHECK GAS TYPE

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