Read Carefully - These instructions are written to help you
prevent difficulties that might arise during installation of
heaters. Studying the instructions first may save you consid-
erable time and money later. Observe the following proce-
dures and cut your installation time to a minimum.
To reduce risk of fire or electric shock:
1. To prevent electrical shock, disconnect all power coming
to heater at main service panel before wiring or servicing.
2. All wiring must be in accordance with the National and
Local Electrical Codes and the heater must be grounded
as a precaution against possible electric shock.
3. Verify the power supply voltage coming to heater match-
es the ratings printed on the heater nameplate before
energizing.
4. This heater is hot when in use. To avoid burns, do not let
bare skin touch hot surfaces.
5. Do not insert or allow foreign objects to enter any ventila-
tion or exhaust opening as this may cause an electric
shock, fire, or damage to the heater.
6. To prevent a possible fire, do not block air intakes or
exhaust in any manner. Keep combustible materials, such
as crates, drapes, etc., away from heater. Do not install
behind doors, furniture, towels, or boxes.
7. A heater has hot and arcing (sparking) parts inside. Do
not use it in areas where gasoline, paint, or flammable
liquids are used or stored.
8. Use this heater only as described in this manual. Any
other use not recommended by the manufacturer may

Installation of Recessed
Back box in Exisiting Construction
1. Provide a wall opening 14-1/2" (362mm)wide x 18-1/2"
(470mm) high at the desired mounting height, but no
closer than 8" (203mm) to any adjacent wall or floor and
36” (915mm) to ceiling. (See Figure 2.)
OTE: Locate so at least one side of the opening is at stud.
2. Power Supply Wiring
OTE: (Wiring Compartment Volume - 119in3(1950cm3).
a. Run a power supply cable into the area above the top
of the wall opening.
b. nstall a cable clamp in the knockout in the top of
back box.
c. nsert power supply cable through cable clamp, allow-
ing at least 6" (152mm) of cable length to remain
inside the back box to facilitate connections.
d. Ground the back box by connecting the supply ground
leadwire to the green ground screw located in the
inside top of the back box.
3. Mounting Back Box
a. Place the back box into wall opening flush with fin-

Installation of Back Box With Optional
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.
OTE: f heater is located in a high traffic area where it may
be subjected to vandalism or abuse, take extreme care to see
that the back box is firmly attached to the wall.
3. Power Supply Wiring
OTE: Wiring Compartment Volume - 119in3(1950cm3).
a. Run a power supply cable into the area of the upper
right corner of the mounting frame.
OTE: f the wiring is to run through the wall, cut a hole in the
area of 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
back box.
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 competely 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. nsert 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. f surface-mounting frame is used, ensure that the
frame is even with all four heater assembly tabs before
tightening screws.
3. Connect the power lead wires (field wiring) to the lead
wires from the heater assembly. See wiring diagram
in next column.
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.

CAUTIO
To assure proper operation of fan, thermostat must not cycle fan
on and off. Follow wiring diagram exactly.
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 postion to obtain room
comfort.
OTE: 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.

Maintenance
TO RESET MANUAL RESET L M T
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.
The heater should be cleaned annually to remove dust and
other foreign material which has collected during the heating
season. This is a simple operation when performed as fol-
lows:
1. Turn off the electric power at main line switch (or
remove all fuses) to disconnect electric power from the
heater. TH S S MPORTANT.
2. Remove the grille (Fig. 4).
3. With a vacuum cleaner nozzle or dust cloth, remove
dust and other foreign material.
4. After cleaning reinstall the grille.
5. Turn on the main line switch (or replace fuses) to
restore power to the heater. The heater is now ready
for another season of operation.
