Note1:
All gas flow rates are referred to Stm
3
/h (1.013 mbar absolute pressure, 15° C temperature) and are valid for G20 gas
(net calorific value H
i
= 34.02 MJ / Stm
3
);
Note2:
Maximum gas pressure = 500mbar (with
Siemens VGD or Dungs MultiBloc MBE)
Minimum gas pressure = see gas curves.
Note3:
Burners are suitable only for indoor operation with a maximum relative humidity of 80 %
