Continued

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.

WARNING: Never install the heater

•in a bedroom or bathroom unless installed as a vented appliance, see page 12

•in a recreational vehicle

•where curtains, furniture, clothingorotherflammableob- jects are less than 42" from the front, top or sides of 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, 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 6.

CHECK GAS TYPE

Use the correct gas type (natural or propane/LP) for your unit. If your gas supply is not correct, do not install in fireplace. Call dealer where you bought the appliance for proper type of appliance.

WARNING: This appliance is equipped for (natural or pro- pane/LP) gas. Field conversion is not permitted.
