15. Cleaning
In order for the unit to function perfectly, it is abso-
lutely necessary to continually clean the combustion
chamber and the ash box.
•
This cleaning must always be carried out when
the unit is cold.
•
Only use a suitable ash vacuum cleaner.
•
Check the connector at regular intervals for a
possible build-up of soot and ash.
•
Clean the glass pane with a special glass cleaner
or oven spray. Do not use any abrasive materi-
als.
Pull out the combustion pan
15.1 Function CLEAN STOVE
This function makes it possible to clean the unit with-
out ashes escaping into the installation room as a
result of underpressure caused by the movement of
the door.
•
Press the OFF button for 2 seconds.
•
The flue gas fan will run at maximum speed,
which causes underpressure in the combustion
compartment so that the ashes do not escape
out of the combustion compartment.
•
It switches off automatically at the end of the
operation.
•
The function can be interrupted by pressing the
OFF button.
15.2 Complete cleaning
The unit must be completely cleaned at least
monthlyeach heating season.
Here, in addition to the cleaning measures already
described, the back wall of the combustion chamber
must be removed and the flue gas ducts that are
behind must be cleaned.
Please proceed as follows:
•
Pull out the combustion pan.
•
Lift up the back wall, pull it forward to the door
and then take it out of the unit to the front.
16. Extraordinary maintenance
Comprehensive maintenance by a specialist is nec-
essary annually for continuously flawless operation of
the unit.
Therefore, the unit displays the message
EXTRAORDINARY MAINTENANCE in the display
after 2000 hours of operation. In addition, an acoustic
signal sounds.
Each time the unit is switched on, the acoustic signal
sounds and the message
EXTRAORDINARY
MAINTENANCE alternates with the operating status
of the unit in the display.
This message can only be reset by an authorised
specialist.
We recommend signing a maintenance contract with
your authorised dealer or Olsberg Customer Service.
That is the only way to guarantee continuously opti-
mum efficiency of your unit.
If the annual maintenance is not performed certifiably,
Olsberg may exclude the customer from guarantee
services or warrantee claims.
