Maintenance/service procedures
Cleaning blower wheel
1. The blower wheel accumulates dust and debris from normal opera-
tion. You will need to clean the wheel blades periodically to prevent
reduction in airflow. To clean blades, remove the two bolts securing
the motor to blower housing.
2. Slide the motor out and rotate to remove and access blower wheel.
3. Use a brush and vacuum to clean each blade and the blower housing
interior.
4. Replace motor/wheel in blower housing and secure with the two
bolts.
5. Push wire slack back into junction box.
Replacing blower motor or wheel
1. If either the blower wheel or motor must be replaced, remove the two
bolts securing the motor to housing.
2. Disconnect the motor wires in the burner junction box.
3. Loosen the Allen screw securing the blower to the motor shaft and
remove the wheel.
4. When assembling the replacement assembly, slide the wheel onto the
motor shaft and use feeler gauges to set a space of 1/8 inch between
the blower wheel and the motor face.
5. Replace the motor/wheel assembly in the housing, wire the motor
leads and secure the motor with the two bolts.
Motor maintenance
The motor is constructed with permanently-lubricated bearings, and re-
quires no oiling. Should you replace the original motor with another type of
motor, occasional oiling may be required, depending on motor design and
manufacturer’s recommendations.
Any time you replace a component or disassemble any part
of the burner for service/maintenance, perform a complete
operational test after reassembly to verify the burner operates
correctly. Failure to verify operation could result in severe
personal injury, death or substantial property damage.
