2.4.1 Preparation
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.
2.4.2 Empty the ash box
Empty the ash box and inspect the seals
By knocking on the vertical wall of the ash box,
you can also check the ash level without opening
the box. A full ash box makes a short, dull thump.
When empty it makes a hollower sound like a drum.
To empty the ash box, fold the locking lever forwards
on the boiler. Remove the ash box from the boiler.

Close the flap on the ash box.

The ash box can be lifted on the bottom with a
handcart and transported.
Open the latch on the lid and empty the ash box.

Check the ash for embers. Never put hot ash into
the waste bin!
If there are large pieces of slag in the ash, the
combustion chamber and the tilting grate must be
checked and the de-ashing interval reduced, if
necessary.
