E: COMBUSTION AIR BLOWER AND MOTOR
Cleaning of the combustion air blower is required if the blades show an accumulation of dust and lint,
or if the character of the flame indicates a deficiency of combustion air.
The motor and blower wheel are removed as one assembly. Locate the motor wires in the electrical
panel. Note the wire connection points in the terminal block and disconnect the motor wires from the
terminal block. Remove the two (2) bolts securing the motor to the burner housing.
Should removal of the blower wheel be necessary for cleaning or replacement of either it or the motor,
the blower wheel must be re-positioned correctly on the motor shaft. (Figure 20)

The gas pressure switches should never require maintenance. If nuisance problems persist, the
switches can be temporarily "jumped" out to bypass the switch's function. If the burner functions
correctly, the switch has malfunctioned.
