Cleaning the exhaust blower and the exhaust stack
The fan wheel in the exhaust blower and the boiler exhaust pipe must be cleaned at least once a year.
1) Disconnect the system from the power supply
2) Unplug the induced draft blower
3) Loosen the wing nuts of the blower motor
4) Loosen the lock nut of the blower motor
5) Pull the blower motor with fan out of the housing.
Note: This procedure can be a bit strict, be careful not to damage the seal!
6) Clean the fan wheel (compressed air / brush)
7) Clean the exhaust gas connection with a brush
8) Check the seals of the blower motor
9) After cleaning, reinstall the blower and reconnect the exhaust pipe to the induced draft blower
10) Make sure that the exhaust pipe to the chimney is tight
Attention
: When cleaning the exhaust gas connection, pay attention to the lambda sensor
and the exhaust gas temperature sensor. Damage may be possible if the connection
piece is not cleaned carefully!
