Note1:
All gas flow rates are referred to Stm

/h (1013 mbar absolute pressure, 15 °C temperature) and are valid for G20 gas
(net calorific value H
i
= 34.02 MJ/Stm

); for L.P.G. (net calorific value H
i
= 93.5 MJ/Stm

)
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%
