16 Maintenance and cleaning
i
Regular maintenance of the heating system is
a prerequisite
- for permanently reliable functioning of the
boiler,
- for energy-saving and environmentally
friendly operation of the boiler,
- Long service life of the boiler.
Basic information on boiler maintenance (including
cleaning activities):
- Part of the boiler cleaning is done automatically in
> 40
- Some activities must be done manually.
On the following pages you will find an overview
of these manually required activities:
- Which activities have to be performed?
- At what frequency must this activity take place?
- Who is responsible for carrying out the respective
activity?
16.1 Required activities - overview
The implementation responsibility of the maintenance
activities is defined according to type and extent (sys-
tem operator SO or qualified personnel QP).

boiler cleaning statistics. The last five boiler cleaning
operations are logged there.
16.1.2 Boiler cleaning - automated processes
- Clean the turbulators by rotating the inside of the
heat exchanger, whereupon the ash falls into the
combustion chamber.
- The ash from the burnt pellets fall through the
stainless steel combustion grate into the com-
bustion chamber.
- The flue ash caused by combustion in the com-
bustion chamber makes its way with the flue gas
through the heat exchanger, through the elec-
trostatic dust collector (optional) and ends up in
the ash container.
ATTENTION - Do not remove the ash con-
!
tainer during automatic ash extraction.
16.1.3 Visual inspection of moving com-
ponents
At the same frequency as boiler cleaning, a visual
inspection of the moving components (air positioning
X
flaps, stainless steel combustion grate, ...) is recom-
mended.
In the event of visible damage, have it repaired by
X
qualified personnel.
