LOCATING HEATER
This heater is designed to be mounted on a wall.
You can locate heater on fl oor, away from a wall.
An optional fl oor mounting stand is included.
IMPORTANT: Vent-free heaters add moisture
to the air. Although this is benefi cial, installing
heater in rooms without enough ventilation
air may cause mildew to form from too much
moisture. See Air for Combustion and Ventila-
tion, page 5. If high humidity is experienced,
a dehumidifi er may be used to help lower the
water vapor content in the air.
For convenience and effi ciency, install heater
• where there is easy access for operation,
inspection and service
• in coldest part of room
If planning to use fan, locate heater near an
electrical outlet. (Only for models
