9.10 Cleaning the flue gas fan and flue gas connector (all models)
If the fan wheels or fan housing become
soiled with strongly adhering soot or tar, it
is essential to clean them, since otherwise
the unbalance of rotating mass can
damage the bearings or the fan wheel
might graze the housing or become blocked.
Do the following:
1.
Release the 4 outer screws of the fan
motor. Do not release the inner screws (with
rubber shock pads).
Important notes: If possible only clean
the fan when dismounted in order to
avoid damage.
2. Clean all fan wheels with a cloth or brush.
Caution:
Do not bend the fan wheels.
Danger of rotary imbalance!
3.
Using a cleaning brush clean the sleeve of
the flue gas sensor inside the flue gas fan
(see picture), removing any soot that may be
clinging to it (which would have an
undesirable insulating effect).
Alternatively you can also dismount the
whole sleeve from the flue gas fan and then
clean it (it is not necessary to dismount the
flue gas sensor TR from the sleeve for this
purpose). Another alternative is to remove
the flue gas connector and then clean the
sleeve by reaching in from the outlet side of
the flue gas fan. Brush carefully in order not
to damage the sensor sleeve or the fan.
The following picture shows the position of
the sleeve of the flue gas sensor TR and
how to clean it.
After completing all cleaning routines
reassemble components in the reverse order
of disassembly.
Caution / Important note:
Be sure also to remove the flue gas
connector and clean it with the cleaning
brush. All servicing is pointless if the flue
connector is clogged with ash or soot, since
then the flue gas will not be drawn off
however clean the stove itself is.
