LOCATING HEATER

This heater is designed to be mounted on a wall.

WARNING: Maintain the minimum clearances shown in Figure 4. If you can, provide greater clearances from floor, ceiling and joining wall.

You can locate heater on floor, away from a wall. An optional floor mounting stand is needed. Pur- chase the floor mounting stand from your dealer. See Accessories, page 30.

WARNING: Never install the heater

•in a bedroom or bathroom

•in a recreational vehicle

•where curtains, furniture, clothing or other flammable objects are less than 36 inches from the front, top or sides of the heater

•as a fireplace insert

•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 5. If high hu- midity is experienced, a dehumidifier may be used to help lower the water vapor content in the air.

CAUTION: When installing heater in a home garage

•heaterpilotandburnermustbe at least 18 inches above floor

•locate heater where moving vehicle will not hit it

For convenience and efficiency, install heater

•where there is easy access for operation, inspec- tion and service
