Installing Blower Assembly

CAUTION: Label all wires prior to disconnection when ser- vicing controls. Wiring errors can cause improper and dan- gerous operation.

CAUTION: Verify proper op- eration after servicing.

Note: If you are using a mantel with your heater, use the following instructions. If your heater is built-in, see For Built-In Installation on page 15.

1.Install snap bushings found in hardware kit into both holes in rear of valve cover shield.

2.Make sure the wire harness is firmly con- nected to the terminals on the blower bracket assembly.

3.Note the wire locations on back of AUTO/ OFF/ON switch. The terminals on back of switch are numbered 1, 2, and 3. Carefully remove red wire from terminal 1 and blue wire from terminal 3. Black wire can remain on middle terminal 2 (see Figure 17).

4.Carefully disconnect green and white wires at their insulated connectors.

5.In top of the heater cabinet, locate the four mounting holes on the outer casing. Align these four holes with those on the blower bracket assembly. Attach blower bracket as-

sembly to the outer casing with 4 #10 screws provided (see Figure 17).

6.Route the wire harness through the hole in left side of baffle. Pull wire harness through lower opening above where the valve shield was re- moved. (see Figure 17).

7.Insert the 4 wire harness into one of the round holes in the rear of the valve cover shield and through the rectangular hole in the front of shield (see Figure 17).

8.Reconnect red wire to switch position 3. Re- connect blue wire to switch position 1. Re- connect green and white wires.

9.Install the switch plate on the valve cover shield with 2 #10 screws provided (see Fig- ure 17). Reinstall the valve cover shield. Route power cord out of the cabinet by inserting it through the bushing on the outer casing (see Figure 17). Plug fan kit into 120-Volt grounded power supply and test operation. Note: When switch is in the AUTO position, the fan will start after the heater has run for a few moments. The fan will continue to run for several moments after the heater has been turned off. When switch is in the ON posi- tion, the fan will run until turned to OFF. Re- install upper louver assembly and hood if pre- viously removed, (see Figure 15, page 13). Close lower louver door.
