When cleaning, turn off the burner… 

Turn off the controls (hold the on/off button down for 10 seconds)  
and let the burner cool down for about 3 minutes,  
when it is completely switched off the burner is ready to be cleaned.  
Unplug the burner, remove the cover and the drop shaft, 
and unscrew the burner from the boiler before continuing. 
 

The burner should be cleaned regularly and whenever necessary. 
This will ensure that the burner runs as economically as possible. 
The more suitable the boiler you have and the better the pellets you use,  
the longer the intervals between each cleaning session. 
 
 
The boiler

… 

Clean the ash out of the boiler and brush off  
all the surfaces to remove any deposits.  
Be very careful of the ash in the backflow valve  
and the chimney pipe. 
The chimney-sweeper DO NOT CLEAN  
the chimney pipe, you must do this yourself … 
An old vacuum cleaner or ash bucket are  
especially suitable,  
as the ash does not normally contain carbon particles or tar. 
 
 
 
 

Combustion heads… 

Remove the ash and any cinders from the grate. 
Remove any remnants of pellets from underneath the grate. 
Wipe the flame indicator. 
Ensure there is nothing in the ventilator.

 

 
 
 
 
 

   

 

 

 

 

 

          VERY IMPORTANT!!! 

                                                                     THE COMBUSTION HEAD WILL                                   

B                                                                                 BE DAMAGED IF THE GRATE IS                                  
N                                                                                 NOT POSITIONED CORRECTLY!!! 

 
 
 
 
 
 
 
Pellet hopper… 

As the pellets you put in the hopper contain detritus,  
the hopper should be completely emptied from time to time. 
The more detritus there is in the hopper, the less the auger feeds,  
which can interfere with the settings cause the burner to cut out. 
The frequency with which you empty the pellet hopper depends entirely on the angle inside of the hopper  
and the quality of the pellets you use. 

 
Restarting after cleaning… 

Reassemble the pellet burner and ignite it (hold the on/off button down for 10 seconds),  
at which point the burner will start automatically. DO NOT FORGET to replace the cover,  
to ensure that the temperature of the combustion chamber is measured correctly.
