16.6 Cleaning Flue Gas Fan and
Connector
If the impellers of the fan or the housing itself
should be contaminated with strongly adherent
soot or tar, they must be cleaned; otherwise, bear-
ing damage can occur to the fan due to imbalance
or the impeller can scrape / become blocked on
the housing. Proceed as follows:
1. Unscrew the four outer screws of the fan
motor. Not the inner screws (with rubber
dampers)! Important: Only clean flue gas
fan when it has been removed in order to
prevent damage.

2. Clean all fan impellers with a rag or brush.
Caution: Do not bend impellers
risk
of imbalancing!

3. Clean fan housing and connector to chim-
ney.

4. The assembly is carried out in reverse se-
quence.
Attention / Important:
Also remove the
connector to the chimney
and
clean
with the cleaning brush. If the connector is
clogged or blocked by ash or soot, general mainte-
nance of the unit will be ineffective because the
flue gases cannot escape.
Observe the country-specific regulations for clean-
ing connectors and chimneys!
