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

); for L.P.G. (net calorific value H
i
= 93,5 MJ / Stm

)
Note2: Maximum gas pressure = 360 mbar (with Dungs MBDLE)
= 500 mbar (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 %
