Maintenance (expert)

2.6.1

Preparation

Before this maintenance, perform all steps for the
preceding maintenance intervals

Before this maintenance, all steps for the
preceding maintenance intervals must be

performed.

WARNING!

The following activities may only be performed by
qualified specialist personnel.

If you carry out these activities without the correspond-
ing specialist training, and above all without the
required experience, safe operation is no longer
guaranteed. The resulting defects and consequential
damage are excluded from the guarantee and
warranty.

Equally an incorrect performance of these activities
can lead to serious injuries.

Stop heating

End the boiler's heating mode with the On/Off switch

 in the boiler overview window. The boiler

performs an ember burnout and then changes to
[Switched off] mode. Press the [De-ash] 

 button to

make the boiler perform a final de-ashing.

WARNING!

Switch off the electricity to the boiler via the mains
switch

Switch off the electricity to the boiler via the mains
switch. This prevents injuries caused by switching
the boiler on inadvertently.

WARNING!

Burns caused by hot parts

Risk of burning on parts located behind the
boiler housing, even after shutting the boiler
down.

Allow the boiler to cool down sufficiently

before starting any activities.

2.6.2

Clean draught fan

Clean the draught fan

Unplug the power supply and remove the draught fan
from the boiler by removing the wing screws.

Fig. 2-51: Draught fan

Remove the ash from the fan housing on the boiler.

Fig. 2-52: Clean the fan housing

Carefully clean the impeller of the draught fan with a
soft brush (not a wire brush) or with compressed air, so
that the impeller does not move out of balance.
Replace the seal on the draught fan.
