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

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

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
