Clean tilting grate
The tilting grate cannot be rotated by hand. Therefore,
press the [De-ash]
button to de-ash the boiler. The
grate is tilted and remains in this position for approxi-
mately 15 seconds.
WARNING!
Danger of crushing due to tilting grate

When the grate is tilted, switch off the boiler with
the mains switch. This causes the grate to remain
in this position so injuries while cleaning the grate
are prevented.
Use the poker to clean the tilting grate and the
openings in it; let the ash fall down.
