fluids, oil or kerosene lamps, etc.) in the air exist, may
discolor walls or cause odors.

lation air may cause mildew to form from too much moisture. See

humidity is experienced, a dehumidifier may be used to help lower
the water vapor content in the air.

• where there is easy access for operation, inspection, and service
• in coldest part of room
An optional fan kit is available from your dealer. See Accessories,
page 26. If planning to use fan, locate heater near an electrical outlet.
