HEATER LOCATION
Unit heaters should be located along outside walls to provide perim-

- can be heated by one or two units. Locate the
unit heater(s) to set up circular air movement within the space.
• Large rooms
- requiring multiple unit installations. Units should
be located so that the discharge air from one unit supports the
discharge from another unit and sets up a circular movement.
• Remove Thermostats
- should be located on interior walls or
posts away from heat sources, cold drafts, and away from heater
discharge air streams.
MOUNTING UNIT HEATER(S)

cm) from walls and 6 ft (183 cm) above floor with discharge parallel
to or away from wall.

ing bracket. Fasten to or suspend the heater from the ceiling
using the holes provided in the bracket.
