(Optional)
Installation of Back Box With
Surface-Mounting Frame
(See Figure 3).
1. Secure back box to wall (with knockouts in upper right
hand corner) using screws and anchors.
2. Hang the surface-mounting frame on the back box.
Ensure that the back edge of the surface-mounting
frame is flush against the wall.
NOTE:
If heater is located in a high traffic area where it may
be subjected to vandalism or abuse, take extreme care to see
that the box is firmly attached to the wall.
3. Power Supply Wiring
NOTE:
Wiring Compartment Volume - 119"3 (1950cm3).
a. Run a power supply cable into the area of the upper
right corner of the mounting frame. All wiring must be in
accordance to National and local Electrical Codes.
Refer to Table 1 for proper wire sizes.
NOTE:
If the wiring is to run through the wall, cut a hole in the
wall near the top of the back box. Run the supply wire
through this hole. Then remove the knockout from the top of
the box and proceed to step c.
b. Remove the knockout on the top side of the frame.
c. Feed the power supply cable through the frame allow-
ing 6" (152mm) of lead to remain inside the frame
d. Secure the power supply cable to the back box
(using cable clamps, connector, or other suitable strain
relief) allowing 6”(152mm) of lead to remain inside the
inner housing.
e. Ground the back box by connecting the supply ground
leadwire to the green ground screw located in the
inside top of the back box.
Installation of Heater Assembly and Grille
After back box is completely installed and no further con-
struction dirt is expected, clean debris from back box, remove
heater assembly from its carton, then refer to Figure 4 and
proceed as follows:
1. Insert the heater assembly into back box, placing
the four mounting holes (with key-hole slots) over the
screws in the back box. Tighten all screws securely.
2. If surface-mounting frame is used, ensure that the
frame is even with all four heater assembly tabs before
tightening screws.
3. Connect the lead wires from the disconnect switch to
the lead wires from the fan deck. (See wiring diagrams)
After connection, push wires back into opening.
4. Turn thermostat to the extreme counterclockwise
position.
5. Mount the grille using four (4) long screws provided.
The screws thread into holes located in the side
flanges of the back box.
6. Push thermostat knob onto thermostat shaft.
Operation
1. Turn power to heater on at main switch panel. Rotate the
thermostat knob fully clockwise. This should energize the
heating elements and the fan, causing air to flow from the
air discharge at the openings in the bottom of the grille.
2. After the discharge air has become warm, rotate the
thermostat knob to the desired position to obtain room
comfort.
NOTE:
For best results, the heater should be left ON con-
stantly during the heating season since the thermostat, when
properly set, will maintain the desired temperature.
IMPORTANT INFORMATION
Maintenance
TO RESET MANUAL RESET LIMIT
Your heater is equipped with a manual reset safety thermal
limit control that will automatically turn the heater off to pre-
vent a fire if the heater overheats. This control is located on
the fan panel assembly between the element and fan blade
and marked “reset.” The red reset button can be seen
through the front grille when the heater is installed. To reset,
allow the heater to cool, then push the red button that is vis-
ible through the hole in the fan panel. The heater should
immediately return to normal operation.
