3. Cleaning work
WARNING
Before starting any cleaning work, the stove must be cool down!
Once the cleaning work is completed, the correct operating status of the device must be re-
established: Put the combustion pot in correctly, close the combustion chamber door.
3.1. Cleaning the surface
Dirt on the upper surface of the stove may be cleaned off with a damp cloth or if necessary with mild soapy
water. You are advised against using corrosive cleaning agents and solvents since these might damage the
surfaces.
3.2. Cleaning the glass panel
To clean the viewing panel, you must first open the stove door. Dirt on the glass panel can be removed with a
glass cleaner or with a damp sponge on which you have sprinkled some of the wood ash present.
(Environmentally friendly). Cleaning the glass panel may only be done with a cooled down stove in the OFF
operating mode.
3.3. Clean combustion chamber “function instruction” Error
F040
• The whole combustion space must be cleaned after 50-hours operation at the latest, or once a week .
• The requirement to clean the fire-box (flickering of the display) appears during heating, in case that the
cleaning interval has elapsed.
• After the fire-box has been cleaned, the error message "Clean the fire-box" will be confirmed automatically.
The condition for automatic confirmation of this error message is that the fire-box door is opened for more
than
60 seconds . This time is necessary for careful cleaning of the fore-box, including the burner.
• This reset of the operating hours counter occurs even if the cleaning of the combustion chamber is
performed before the 30 operating hours have run provided that the stove is in “Off” operating status and the
door is open for longer than 60 seconds during cleaning.
3.4. Cleaning the combustion pot - weekly
During operation, deposits may form in the combustion pot. How quickly the combustion pot becomes dirty
depends solely on fuel quality. The deposits or encrustations must be removed from time to time.
WARNING
If this is not done, the clinker will continue to accumulate. Then the device will no longer be able to ignite
properly. Pellets can pile up in the combustion pot. In extreme cases, this can reach all the way back to the
pellet chute. Backfire in the pellet container and smouldering in the pellet tank might possibly result.
This will destroy your device and is not covered in your guarantee.
