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.

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.

exhaust in any manner. Keep combustible materials, such

as crates, drapes, etc., away from heater. Do not install

behind doors, furniture, towels, or boxes.

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-

ished wall surface on bottom and sides of box. (Top

flange of back box should protrude approximately 1/2"

(13mm) from finished wall surface).

b. Secure the back box in place with wood screws or nails.

OTE: For correct wire sizing, please refer to the

ational Electrical Code, Section 310. Only use copper

wire rated at least 75° C Do not use alluminum wire with

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.

IMPORTA T I FORMATIO

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.
