Pellet burner GP xx sc                                                                                                 19 

If the gathered fuel over the burner’s fire-grate has not been removed, after  
successful ignition (for example after restarting the burner) it might lead to difficult  
firing of relatively larger amount of fuel, to separation of inflamed gasses and  
respectively to their explosive ignition. Such explosive ignitions might lead to  
mechanical damages of the appliance, to which the burner’s main module is  
mounted.  

 

  If  the  photic  sensor  does  not  register  a  burning  process  during  operation,  then  the 

fuel ignition algorithm starts again; 

  If  two  unsuccessful  attempts  for  ignition  have  been  performed,  for  example  in  case 

the fuel has been depleted, then the burner stops the main algorithm and transits to 
emergency mode, which is shown on the display panel and should be considered as 
a necessity for intervention by the user, as the failure reason requires removal. After 
the failure has been removed the new start has to be performed through consecutive 
switching  OFF  and  then  back  ON  (restarting)  of  the  appliance’s  common  power 
supply, to which the burner is also connected.    
 

Before starting the burner’s fire-grate has to be checked for presence of  
unburned fuel and ash. If so, the fuel and the ash residues have to be removed. 
 

 

  If the power supply has been interrupted the burner will start automatically when the 

supply restores.   

 

During operation the burner might transit to final combustion and blowing, if the  
relevant option for cleaning during operation is switched ON – parameter  

“Max.comb.time”.

 This parameter is in

6.2.5.  OPERATIONAL PARAMETERS FOR ADJUSTMENT OF A PELLET BURNER „GP 

XX SC”. 

 
The  operational  parameters  are  preliminary  set  in  the  burner’s  control  module  by  the 
manufacturer, as the user and/or other attending staff are not required to perform changes. 
In order to achieve optimal and economic operational conditions of the burner it is necessary 
to assign such heating output that will provide optimal operation and low fuel consumption. 
The  practice  shows  that  the  constant  operation  of  the  burner  provides  optimal  fuel 
consumption.  
  
The  controller’s  display  panel  and  the  keyboard  are  used  to  show  information  about  the 
burner’s operation mode. The operational parameters adjustments have to be performed by 
trained specialist.
