Boiler output setting
In following tables (table no. 5 and table no. 6) there are stated only orientation values and are valid
only for tested fuel.
Tested fuel:
pelets Ø 8 mm
Efficiency 16,4 MJ/kg
! Important notice:
Stated values changing in dependence on kind, quality and humidity of used pellets. Therefore may
be necessary some corrections during adjustment of feeding cycle (rate of time for fuel feeding and
time of fuel afterburning). F.e. if will appear on the grill and in the ash-pan sliver, is evident that
feeding speed is higher than burning speed and is necessary the feeding cycle decrease.
