(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 of 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 Table 1 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 allowing 6" (152mm) of lead to remain inside the back box.

e. Secure the power supply cable to the back box (using cable clamp, connector, or other suitable strain

relief) allowing 6" (152mm) of lead to remain inside the back box.

f. Connect supply wires to blue wires of disconnect switch using wiring connectors (see wiring diagram).

g. Ground the back box by connecting the supply ground leadwire to the green ground screw located in the inside top of the back box.

h. Secure disconnect switch bracket in place.

Installation of Heater Assembly and Grille

After back box is completely installed and no further construction 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 two disconnected switch wires to the heater control switch (thermostat) leads using wire nuts. After connection, push wires back into the opening.

4. Turn thermostat to the extreme counterclockwise position.

5.Push disconnect switch into ON position.

6.Mount the grille using the four (4) long screws provided. The screws thread into holes located in the side flanges of the back box.

7.Push thermostat knob onto thermostat shaft.

OPERATION OF THE MANUAL RESET SAFETY THERMAL LIMIT CONTROL IS AN INDICATION THAT THE HEATER HAS BEEN SUBJECTED TO SOME ABNORMAL CONDITION. IT IS RECOMMENDED THAT THE HEATER BE CHECKED BY A REPUTABLE ELECTRICIAN OR REPAIR SERVICE TO ENSURE THE HEATER HAS NOT BEEN DAMAGED.

Operation

1. Rotate the thermostat knob fully clockwise. This should energize the heating elements and fan causing warm air to flow from the hot air discharge at the openings in the bottom of the grille.

2. After the operation check, rotate the thermostat knob to the desired position to obtain room comfort.

3. For continuous fan-only operation (elements will not be energized) rotate thermostat knob where indicator dot on knob is aligned with FAN.

4. There will be a short delay from the time the unit is tu rned on until the fan engages. This is to allow the elements time to warm up. The fan will also continue to run once the unit is turned off to allow the elements time to cool.

4

NOTE: For best results, the heater should be left “ON” constant -
ly during the heating season because the thermostat, when prop-
erly set, will maintain the desired temperature.
	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 prevent a fire if
the heater overheats. Th is control is loca			ted 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 visible 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 sea-
son. 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 the grille (Figure 4) and turn the disconnect switch to
the OFF position.
	CAUTION		!
DO NOT USE WATER OR DAMP CLOTH FOR		CLEANING		AND DO
NOT DISTURB THE HEATING ELEMENT.
3. With a vacuum cleaner nozzle or dust cloth, remove dust
and other foreign material.
4. After cleaning, turn disconnect switch to ON position and
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.
