Emptying the ash container
The ash container must be emptied at appropriate intervals depending on energy
requirements and fuel quality.
If the ash container is full before you check the ash level, the warning “ash box
full, please empty” will appear on the display.

False air infiltration via the ash screw duct can lead to uncontrolled combustion
and the risk of accidents.

status.

container
