1. Cleaning and maintenance work
The functioning of your device depends to a large extent
on regular expert maintenance. Because of the ash
accumulation resulting from the combustion of wood
pellets, constantly recurring cleaning and maintenance
work needs to be carried out. This will permit operation
to be as trouble-free as possible.
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. This
results in lower heat output and an increased fan
rotation
speed.
We therefore recommend
checking and/or cleaning the flue gas passes
after 1,000 kg of pellets at the latest. (See
Figure 4 a+d).
Attention!
Devices that are not maintained in accordance with
our specifications must not be operated. Failure to
observe this point will invalidate all guarantee
claims.
As soon as you detect ash and clinker deposits in the
cold combustion pot, it must be cleaned. (
See Figures 1
+2). 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
.
Attention!
Before starting any cleaning work, the stove must be
cool down and set to "Off"! 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.
1.1. 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.
1.2. 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.
1.3. Clean combustion chamber “function
instruction” Error F040
• The entire combustion chamber is to be cleaned with
an ash vacuum cleaner at intervals of no longer than
30 operating hours.
• 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.
1.4. 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
.
Cleaning the combustion pot may only be done with a
cooled down stove in “OFF” operating mode. Otherwise
there is a risk of burns!
To this end the combustion pot must be removed from
the stove. Once the combustion pot has been removed,
any residual ash that is in the stove underneath the
combustion pot must also be removed.
After cleaning, the combustion pot is to be put back into
the right position in the burner seat. Check the correct
seating of the combustion pot again so as to avoid poor
seals.
