Installation of Heater Assembly and Grille

After back box is completely installed and no further construction dirt is expected, clean debris from back box and remove heater assembly from its carton. Then refer to Figure 5 and proceed as follows:

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. 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 visible through the hole in the fan panel. The heater should immediately return to normal operation.

MAINTENANCE INSTRUCTIONS

It is important to keep this heater clean. Your heater will give you years of service and comfort with only minimal care. To assure efficient operation follow the simple instructions below.

Fig. 5

1. Insert the heater assembly into back box, placing the four mounting holes (with key-hole slots) over the screws in the 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 heat control switch (thermostat) leads using wirenuts. 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 grille tabs over back box flange (top). Sheet metal flange on top end of grille hooks onto vertical flange on back box.

7. Insert two screws through tabs provided below bottom louver. Tighten screws until grille is pulled flush to the wall (or surface mount frame). BE CAREFUL, DO NOT OVERTIGHTEN

SCREWS.

OPERATION INSTRUCTIONS

1. Heater must be properly installed before operation.

2. 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 bottom of the grille.

3. 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 thermostat, when properly set, will maintain the desired temperature.

ALL SERVICING BEYOND SIMPLE CLEANING THAT REQUIRES DISASSEMBLY SHOULD BE PERFORMED BY QUALIFIED SERVICE PERSONNEL.

TO REDUCE RISK OF FIRE AND ELECTRIC SHOCK OR INJURY, DISCONNECT ALL POWER COMING TO HEATER AT MAIN SERVICE PANEL AND CHECK THAT THE ELEMENT IS COOL BEFORE SERVICING OR PERFORMING MAINTENANCE.

User Cleaning Instructions:

1. After the heater has cooled, a vacuum cleaner with brush attachment may be used to remove dust and lint from exterior surfaces of the heater including the grille openings.

2. With a damp cloth, wipe dust and lint from grille and exterior surfaces.

3. Return power to heater and check to make sure it is operating properly.

Maintenance Cleaning Instructions:

(To be performed only by Qualified Service Personnel)

At least annually, the heater should be cleaned and serviced by a qualified service person to ensure safe and efficient operation. This should include the removal of the grille and as necessary, the heater from the back box, to clean residue from the unit. After completing the cleaning and servicing, the heater should be fully re-assembled and checked for proper operation.
