Nominal thermal load of the burner of series “GP” 

After the pellet burner has been started successfully (the fuel in the 

combustion chamber is ignited) and the heat consumer unit, which demands heat 
energy is heated up and tempered, one could assume that the system: burner-
heat consumer unit are in steady-state mode and thermally tempered. The 
adjustment process should be performed in such steady conditions, followed by 
appropriate air control flap adjustment. In this mode an installer should perform 
so called “warm test” of the system, following the active norms and 
requirements. Also adjust the position of the lever, which controls the air flow 
rate, color synchronized according to the position of the thermal capacity 
potentiometer of the burner, in order to achieve high efficiency combustion 
process. 
 

NOTE : 

It is not recommended to operate the burner at thermal load lower than 

minimal thermal capacity, indicated in its technical information, as such 
conditions are characterized with decreased efficiency. If the unit should operate 
at thermal capacity, lower than nominal operation mode, one should perform 
local adjustment of the operating parameters of the burner – both the thermal 
capacity and the air flow rate, in order to ensure high efficiency and high 
reliability of the system; 

ATTENTION:

 Air flow rate considerably influence the operating mode of the 

burner and the overall system performance and efficiency – if the air flow rate is 
less than required, than the fuel is partially unburned due to low mixing 
intensity and decreased combustion efficiency. In case that the air flow rate 
exceeds the optimal air flow rate (for the operating thermal capacity of the 
burner) the result will be also a sensible decrease of the combustion efficiency 
due to intensive cooling of the combustion process and respectively increased 
amount of unburned fuel as well. The above mentioned characteristics should be 
carefully considered and appropriate adjustment of the combustion process 
properties should be done in order to achieve high efficiency and economic 
performance of the system. The air flow rate adjustment is made by adjustment 
of the position of the lever, synchronized to the position of the thermal capacity 
control potentiometer, which allows to achieve optimal operating conditions and 
high efficiency of the burner.

Adjustment of the thermal capacity of the burner 

Adjustment of the thermal capacity of the burner is performed by simultaneous 
adjustment of the position of the thermal capacity potentiometer (i.e. the fuel 
flow rate) and the air flow rate, controlled by the flap of the burner’s air fan. 
Adjust the air control flap position according to the position of the thermal 
capacity potentiometer (the so called color synchronization).
