Remove rear shield (2 screws) and bottom reflector (4 screws). (See Figure 1) 2. Align blower cushion with bottom assembly air discharge opening. Foil face side of blower cushion should be placed upward. 3. Align blower housing with blower cushion and use two #10 x 1/2” (13mm) hex-head screws to attach blower housing to bottom assembly. (See Figure 2) 4. Save bottom reflector and rear shield (removed in Step 1) in the even the blower housing is removed from room heater. Attention! Bottom reflector and rear shield must be attached to bottom assembly whenever the blower housing in removed from the room heater and the room heater is in operation. 5. Remove switch box cover from the switch box by removing the #8 x 1/4” (6mm) hex-head screw. 6. There are two screw holes on the lower back of the combustion chamber. Use only the left screw hole for mounting. 7. Withtheswitchboxperpendiculartothecombustionchamber, align the round clearance hole on the switch box with the left screw hole on the combustion chamber (See Figure 3). 8. Attach switch box to the combustion chamber using the #10 x 1/2” (13mm) hex-head screw provided. 9. Attach switch box cover to the switch box by using the #8 x 1/4” (6mm) hex-head screw. (See Figure 4) Figure 3 Figure 4 12822-3-0406 Page 16 Page 17 12822-3-0406 Attention: Wiring harness on blower is factory assembled and installed. If wiring harness becomes disassembled, use the following steps to reassemble the wiring harness. 1. Attach (1) pin terminal from black (hot) wire, smooth insulation on cord set to (1) socket terminal on fan control assembly. 2. Attach (1) pin terminal from black (neutral) wire, ribbed insulation on cord set to (1) socket terminal from white (neutral) wire on motor. 3. Attach (1) pin terminal on fan control assembly to (1) socket terminal from black (hot) wire on motor. 4. Attach green ground wire beneath one of the #10 x 1/2” (13mm) screws on the blower housing. Fan Control The automatic fan control is located in the switch box. The switch box is attached to the front of the blower assembly. The switch box is adjacent to the combustion chamber. The fan control is a nonadjustable automatic type. The fan control will require between 5 and 10 minutes of main burner operation before the fan control “closes” and activates the blower. The blower will continue to run between 5 and 10 minutes after the main burner shuts off, before the fan control “opens” and deactivates the blower.

This appliance is equipped with a three-prong [grounding] plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug. For an ungrounded receptacle, an adapter, which has two prongs and a wire for grounding, can be purchased, plugged into the ungrounded receptacle and its wire connected to the receptacle mounting screws. With this wire completing the ground, the appliance cord plug can be plugged into the adapter and be electrically grounded. A 7/8” (22mm) hole is provided in the junction box for use with a conduit connector if local codes require this type of protection. Wiring Diagram If any of the original wire as supplied with the appliance must be replaced, it must be replaced with type 125oC wire or its equivalent. Cleaning The blower wheel will collect lint and could require cleaning once a year. If the air output decreases or the noise level increases, it indicates a dirty wheel. Complete removal of the wheel and scrubbing it with a brush under flowing water is recommended. Oiling The blower motor has an oil hole located on each end of the motor. Use #20 motor oil only. It is best to oil the motor several times during the heating season using 2 or 3 drops each time. If the motor fails to start and hums, it could be a tight bearing due to lack of oil. This may be corrected by pouring kerosene in the oil holes, allowing to stand for a few hours and then oiling properly. CAUTION: Label all wires prior to disconnection when servicing controls.
