Cleaning the Exhaust/Combustion Blower:
To clean the combustion blower, unplug the stove,
remove the surround and the left cabinet side.
Remove the four screws (Figure 7) with a Philips
screwdriver. The motor can now be pulled from the
fan housing.
The blower cooling fan and main blade can be
vacuumed once the motor is removed. Before rein-
stalling, vacuum out the blower housing and the
flue gas passages leading to and from the com-
bustion blower.
Clean the inner surface of the Proof of Fire Switch
located on the combustion air channel. When rein-
stalling the motor, check the gasket between the
motor and the fan housing, a new gasket may need
to be installed if damaged. Place the motor back
on the fan housing (motor down) and rotate clock-
wise to lock the flange, tighten the four screws with
a Philips screwdriver.
