2.4 Regular maintenance
2.4.1 Preparation
Stop heating
Stop the heating mode of the boiler with the on / off
switch in the overview of the boiler. The boiler
emits a glowing charge and then switches to operating
mode [Switched off]. Then press the [De-ash] key
to allow the boiler to perform a final ash removal.
2.4.2 Empty the ash box
Emptying the ash box and checking 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 on the
boiler forward. Remove the ash box from the boiler.

Check the ashes for pieces of 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.
Check if the seal in the lid of the ash box is intact and
replace if necessary.
