HEATING FROM THE SAME VERSATILE UNIT

These heavy-duty heaters provide spot heating for hard to heat ar-

eas, or they can be used as the primary source of heat for areas not

reached by an existing heating system.

The fan and motor are carefully matched to insure quiet, trouble-free

operation and fan blades are precision balanced before installation.

Heaters in all capacities (3, 5, 7½, 10 or 12kw) have the same di-

mensions, and use the same mounting brackets. All components and

controls, including thermostat, transformers, relays, and switches are

enclosed inside the case. Wiring is simple and all heaters can oper-

ate from a single power source.

HEATER LOCATION

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

eter air circulation. The discharge air should wipe the walls without

blowing directly on them. (Figure 1)

• Small rooms - can be heated by one or two units. Locate the unit

heater(s) to provide 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 provides a circular air movement.

• Remote thermostats - should be located on interior walls or

posts away from heat sources, cold drafts, and away from heater

discharge streams.

MOUNTING UNIT HEATER(S)

CAUTION: Heater must be mounted a minimum of 10 in. (25.4cm)

from walls and 6 ft (183 cm) above oor (8 ft (244 cm) for vertical air

ow) with the discharge parallel to or away from wall.

• MOUNTING BRACKET - The heater is shipped with a mount-

ing bracket packed separately in the carton. Secure the bracket

to threaded attachment points on the sides of the heater with

30, 45, 60, 75, or Vertical), remove corresponding knockouts on

sides of the heater, then screw the remaining two bolts into the

threaded holes in the bracket so that the bolts pass through the

knockout holes. The unit is now ready for hanging.

• CEILING MOUNTING - Fasten the heater securely to the ceiling

using the center hole in the bracket or the two holes on either side

of the center hole. The Unit mounting bracket may be attached
