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, 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 damper closed.

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 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 gas, do not install heater. Call dealer whereyouboughtheaterforpropertypeheater.

INSTALLATION AND CLEARANCES (Vent-Free Operation Only)

WARNING: Maintain the mini- mum clearances. If you can, pro- vide greater clearances from floor, ceiling, and adjoining wall.

Carefully follow the instructions below. This will ensure safe installation into a masonry, UL127-listed manufactured fireplace, or listed vent-free firebox.

Minimum Clearances For Side

Combustible Material, Side Wall,

and Ceiling

A.Clearances from the side of the fire- place cabinet to any combustible ma- terial and wall should follow the dia- gram in Figure 4.

Example: The face of a mantel, book- shelf, etc. is made of combustible ma- terial and protrudes 3 1/2" from the wall. This combustible material must be 4" from the side of the fireplace opening (see Figure 4).

Note: When installing your gas logs into a manufactured firebox, follow firebox manufacturer’s instructions for minimum clearances to combustible materials.

B.Clearances from the top of the fireplace opening to the ceiling should not be less than 42 inches.
