Before this maintenance, perform all steps for the
preceding maintenance intervals
Before this maintenance, all steps for the
preceding maintenance intervals must be
performed.
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.
Switch off boiler via mains switch
WARNING!
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
Even after the boiler has been switched off,
there will still be a danger of burns caused
by the cleaning and maintenance covers of
the combustion chamber and the heat
exchanger, and by the combustion chamber door.
These parts cool off more slowly, so they may still be
hot.
Allow the boiler cool off long enough, or wear
appropriate protective clothing.
Air intake in installation room must be clear
Air intake for the boiler in installation room must be
clear. It may not be shut or closed.
Cleaning the flue pipe
Sweep the flue pipe from the flue outlet to the chimney,
and remove flue ash from the chimney using a vacuum
cleaner.
Sweep the ash into the chimney, not into the
boiler.
Clean combustion chamber
Carefully pull the temperature sensor of the
combustion chamber out by loosening the screw on
the boiler.
