Attention: Wiring harness on blower is factory assembled and installed. If wiring harness becomes disassembled, use the fol- lowing 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 insu- lation 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 non- adjustable 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.

Wiring
The appliance, when installed, must be electrically grounded in ac- cordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 or Canadian Electrical Code, CSA C22.1, if an external electrical source is utilized. This appliance is equipped with a
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 equiva- lent.
CAUTION: Label all wires prior to disconnection when ser- vicing controls. Wiring errors can cause improper and danger- ous operation. Verify proper operation after servicing.
Warning:
Unplugging of blower accessory will not stop the heater from cycling. To shut heater off:
1.Turn temperature dial or thermostat to lowest setting.
2.Turn knob n gas control to “OFF,” depressing slightly. Do not force.
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 scrub- bing 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.
