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 con-
siderable time and money later. Observe the following pro-
cedures and cut your installation time to a minimum.
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 stored.
8. Use this heater only as described in this manual. Any
other use not recommended by the manufacturer may
cause fire, electric shock, or injury to persons.
9. This heater is not approved for use in corrosive atmos-

ing approximately 6" (152mm) of cable length to
remain inside the wall housing to facilitate connections.
3. Mounting Wall Housing
a. Place the wall housing into wall opening flush with fin-
ished wall surface on bottom and sides of box. (Top
flange of wall box should protrude approximately 1/2"
or 12.7mm from finished wall surface).
b. Secure the wall housing in place with wood screws or
nails.
4. Wiring Disconnect Switch
a. Connect the power supply wires to the blue wires of the
disconnect switch using wire connectors (see wiring
diagram, pg. 3.)

Installation of Housing 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 - 119in3(1950cm3).
a. Run a power supply cable into the area to the upper
right corner of the mounting frame. Arrangement of
wiring to this point must be in accordance with National
and Local codes. Refer to specifications on page 2 for
proper wire size.
NOTE: If the wiring is to run through the wall, cut a hole
in the area of the top of the wall 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. Remove disconnect switch bracket by loosening the
two screws on the right side.
d. Feed the power supply cable through the frame allow-
ing 6" (152mm) of lead to remain inside the inner hous-
ing (using cable clamp, connector, or other suitable
strain relief).
e. Secure the power supply cable to the inner housing
(using cable clamp, connector, or other suitable strain
relief) allowing 6" (152mm) of lead to remain inside the
inner housing.
f. Connect supply wires to blue wires of disconnect
switch using wiring connectors (see wiring diagram,
next column).
g. Ground the housing by connecting the supply ground
leadwire to the green ground screw located in the
inside top of the housing.
h. Secure disconnect switch bracket in place.
Installation of Heater Assembly and Grille
After wall housing is completely installed and no further con-
struction dirt is expected, clean debris from wall housing,
remove heater assembly from its carton, then refer to Figure
4 and proceed as follows:
1. Insert the heater assembly into wall housing, placing
the four mounting holes (with key-hole slots) over the
screws in the housing. 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 two disconnected switch wires to the heat-
control switch (thermostat) leads using wirenuts. (see
wiring diagram, next column) After connection, push
wires back into the opening.
4. Turn thermostat to the extreme counterclockwise
position.
5. Push disconnect switch into ON position.
6. Install (2) plastic covers on back box as follows: (See Fig. 4)
NOTE: Both top and bottom plastic covers are identical.
•TOP - Align the screw bosses on the back of the plastic
cover with the second hole down from the top of the
back box and attach it with the two screws provided.
•BOTTOM - Align the screw bosses on the back of the
other plastic cover with holes at the bottom of the back
box that are just above the fan deck mounting screws
and attach it with two screws provided.
7. Remount the wire compartment cover. Install the front
cover by hooking the (2) tabs on the one side then rotat-
ing the front cover into place making sure that all four tabs
are snapped onto the front cover.
8. Fit the thermostat knob onto the thermostat shaft and
push into place.

Operation
1. Rotate the thermostat fully clockwise. This should
energize the heating elements and cause warm air to
flow from the hot air discharge at the openings in the bot-
tom of the grille.
NOTE: This heater is provided with a fan delay control that
allows the heating element to warm prior to the fan coming
on. This delay will also allow the fan to operate for a short
period after the heating element has been turned off to
remove the residual heat from the heater.
2. After the operation check, rotate the thermostat to
the desired position to obtain room comfort.
NOTE: For best results, the heater should be left “ON”
constantly during the heating season because the thermo-
stat, when properly set, will maintain the desired tempera-
ture. 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.
Once each year the heater should be cleaned to remove dust
and other foreign material which has collected during the
heating season. This is a simple operation when performed
as follows:
1. Turn off the electric power at main line switch (or remove
all fuses) to disconnect electric power from the heater.
THIS IS IMPORTANT.
2. Remove thermostat knob.
3. Remove front cover by depressing plastic snap tabs with
a flat bladed screw driver as shown in Figure 5. Release
both tabs on one side then rotate the front cover off of the
fan deck.
4. With a vacuum cleaner nozzle or dust cloth, remove dust
and other foreign material.
5. After cleaning, turn disconnect switch to ON position and
reinstall the grille.
6. 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.
