Note1:
All gas flow rates are referred to Stm
3
/h (1013 mbar absolute pressure, 15 °C temperature) and are valid for G20 gas
(net calorific value H
i
= 34.02 MJ/Stm
3
); for L.P.G. (net calorific value H
i
= 93.5 MJ/Stm

)
Note2:
Maximum gas pressure = 360mbar (with
Dungs MBDLE)
= 500mbar (with
Siemens VGD)
Minimum gas pressure = see gas curves.
