Before starting with the cleaning and /or maintenance, the appliance must be shut
down and disconnected from the mains (Emergency - OFF). Allow the appliance to
cool down – nevertheless we advise you to be careful – some components in the
fire chamber can still be hot. It is likely that there are still embers in the ash. At no
time should you put unburnt material from the firebox into the storage container
– danger of spontaneous ignition.
When burning solid fuel, ash and soot are generated, therefore cleaning and
maintenance are necessary at regular intervals. If these are omitted, malfunctioning
will occur which will be excluded from our liabilty.
Only a clean and properly adjusted appliance is an economical heating appliance.
How often cleaning is required depends on the operating period, the output of
the appliance and on the pellet quality. Wood pellets contain non-combustible
components (mineral nutrients) which are left behind in the form of ash. Depending
on the operating period, the output of the appliance and on the pellet
quality it is likely that the viewing window becomes cloudy which can range
from light to coal black. This is a natural process which happens when burning
biomass and does not represent a flaw. To minimize the sootingup (also if the
stove is in permanent use for several days), the viewing window will be ‚airwashed’
(airwash system).
Before cleaning, wait until the appliance is cool down. So you prevent yourself
from embers and hot components.
Fire hazard !
Cleaning firebox (figure 66)
• Clean firebox with the aid of the supplied cleaning utensil.
• Remove deposits on the pellet burner block and flame temperature sensor by
means of the supplied cleaning brush.
Vacuum-cleaning firebox
Allow the appliance to cool down completely and use vacuumcleaner only in
combination with an ‘ash box’– Fire hazard!!
Cleaning pelets storage container
Remove deposits (dust etc.) from the auger and storage container.
Cleaning oven (figure 67-69)
• Lift cooking plate.
• Remove deposits from the interior of the stove blagerungen.

The oven sensor for the pellets module protrudes at the side from the oven protection.
Do not clean with sharp objects!!
Remove deposits from the appliance, in particular from the pellet burner block by
means of the cleaning brush provided. For details see “Cleaning…”.
The extract fan casing for the pellets module is fitted at the bottom of the oven
module. Do not sweep deposits into the interior of the casing. Do not clean the
extract fan casing with sharp objects! This would result in the fan wheel being
damaged.
