PRINCIPLES OF OPERATION
When the thermostat calls for heat, the elements
are immediately energized, a fan delay brings
on the fan after the elements are heated allowing
warm air to circulate. When the thermostat is
satisfied, the elements are de-energized and the
fan purges the heater of residual heat.
The heater wattage may be field adjusted only on
model BH-P961-U5000V-T. Select the desired
wattage from Fig. 1 and move color coded
jumpers as indicated.

INSTALLATION INSTRUCTIONS
All electric unit heaters are shipped fully
assembled. Installation includes hanging the
unit and electrical wiring to the unit.
The wall and/or ceiling structure must be
sufficient to support the combined weight of
the heater and any mounting bracket and
accessories.
Be sure power source is de-energized before
installing heater. Check heater voltage and
phase listed on heater data label on
back of unit to make sure they are the
same as the electrical service supplied.
MOUNTING THE HEATER
Select the mounting location. Be sure to observe
the minimum mounting clearances as shown in
Figure 2.
The heater can be mounted either from the
ceiling or wall depending on the application.
The mounting bracket is supplied with 3/8” holes,
10 inches on center for threaded rod mounting or
direct mounting to the structure.
The heater cabinet also has 3/8” weld nuts 10” on
center to allow threaded rod mounting without the
bracket.
1. Install the mounting bracket in the desired
location with threaded rod or hardware that is
appropriate for the mounting surface. If using
threaded rod, two nuts, one on the top and
one on the bottom of the bracket along with a
split washer is suggested.
2. Secure the heater to mounting bracket, using
the 1/4-20 x 3/4” machine screws and lock
-
washers provided.
3. Position the heater, aligning the bracket holes
with the cabinet holes and secure bracket
to the cabinet with the 1/4-20 x 1/2” machine
screws and nuts that are provided. With the
mounting bracket in the vertical position the
1/4” nuts are not necessary, weld nuts are
supplied in the cabinet.
