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.
