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 30-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.
WARNING
Cleaning the combustion pot may only be done with a cooled down stove in “OFF” operating mode.
Otherwise there is a risk of burns!
• Take out the burner bowl from the stove.
• Remove the remains of ashes and slag.
• After the cleaning, mount the burner bowl back to its proper position on the burner rest.
• Re-check the proper seating of the burner bowl, in order to avoid any lack of tightness.

4. Maintenance work
WARNING
Before starting any cleaning work, the stove must be cool down! The mains plug must be pulled out of
the power supply socket (always in advance)!
WARNING
Devices that are not maintained in accordance with our specifications must not be operated. Failure to
observe this point will invalidate all guarantee claims.
4.1. Cleaning of the ash pan - once a week
WARNING
The frequency of maintenance in turn depends to a large extent on the pellet quality (ash content). Quality
pellets have a low ash content of about 0.2-0.3%. However, if the ash content is higher (0.5% and over), the
interval from maintenance to maintenance is reduced and the accumulation of ash increases by 2 or 3 times.

4.2. Cleaning of the exchanger - once a week
CAUTION
We recommend you to clean the conduits of combustion products and the exchanger once in a week.
Please perform the short-time cleaning in two steps:
4.2.1. Vertical cleaning of the exchanger
• For the purposes of vertical cleaning, move the cleaning lever 5 times at least, in compliance with the Fig. 2.

4.2.2. Horizontal cleaning of the conduits of combustion products
• Get the cleaning bar from the rear cover of the stove. Next, remove the cover plug and dismount the screw
M10x70 by means of an Allen wrench, located behind the ash-pan door. After having finished the cleaning
by means of the blade, mount the screw and fit the cover plug to their places again. (see Fig. 3a-3c).

4.3. Cleaning of the exchanger
CAUTION
Check and clean the flue-gas ways, exhaust (flue-gas) fan and flue-gas ducts at the latest after 1000 kg of
pellets have been consumed. Clean with a brush or an ash extractor.
CAUTION
After completion of the cleaning make sure that when putting back the covers, the seals are seated in the right
positions. It is essential to replace defective seals.
Please perform the long-time cleaning in two steps:

4.4. Cleaning the pellet container - annual maintenance
• Heat the pellet stove until the storage tank is completely empty.
• Then the protective grille (1) in the pellet tank may be removed.
• Then clean the tank and the intake of the screw conveyor housing with a vacuum cleaner.
• After cleaning, it is essential to put back the protective grille. When doing this, make sure that no screws fall
into the pellet tank so as to avoid consequential damage to the screw conveyor.
