Clean the combustion chamber and flue
collection box
To gain access to the combustion chamber and the
flue collection box in front of the fan, the panel
on top of the boiler and the heat exchanger cover
must be removed.
Removing panels
Loosen the screw next to the flue pipe and press
the button on the side of the panel. Then the
panel can be removed from the top of the boiler.

Clean with the poker
Use the poker (stored behind the front panel
above the ash box) to remove the combustion
chamber cover from the combustion chamber and
scrape the ash from the walls. Sweep the ash into
the combustion chamber and the tubular heat
exchanger.

Flue collection box
Remove the ash, which is now on the grate and in
the tubular heat exchanger, from the boiler with
an ash removal.
An ash removal can be started by pushing the
button in the "Boiler" overview.
The turbulators do not need to be
removed.
Are there tar deposits on the tubular heat
exchanger?
If there are tar deposits on the tubular heat
exchanger, contact customer service. The cause for
the incorrect air measurement must be identified
and corrected (leak air through lambda flange or
heat exchanger cover, incorrectly calibrated lambda
probe, incorrect differential pressure measurement
at the air intake).
