Motor Replacement Procedure:
1. Follow the directions on Page 47 for detaching the diesel
burner.
2. Remove the four ignition coil screws that secure the ignition
coil to the protection cap. Lift the ignition coil to disconnect
its wires from the C-plug harness prior to removing. Remove
the protection cap from the diesel burner so that the motor
clutch halves are exposed.
3. Remove the three Hex-Head screws that secure the motor
and flange assembly to the blower housing. Remove the
motor and flange assembly along with the clutch halves.
Disconnect the motor’s black (+) and brown (-) wires from
the C-plug harness’ wires.
4. Detach the motor from the motor flange by removing the
two Philips heads screws that fasten the two parts together.
5. The motor must be mounted to the flange with the wires
and drain hole pointing downward, and the recessed edge
of the motor flange pointing upward. This will ensure a
proper protection cap fit.
6. Reinstall a clutch half on both the new motor’s shaft and the
combustion air blower shaft. Attach the motor and flange
assembly, with the recessed edge of the motor flange in-
line with the wiring access slot of the blower casing to the
blower housing with the three Hex-Head screws.
7. Connect the black (+) and the brown (-) wires of the new
motor to the C-plug harness pin 8 (+) and pin 5 (-). Feed the
C-plug harness’ wires back through the wiring access hole
in the protection cap.
8. Reinstall the protection cap. Reconnect the motor’s wires
