Combustion chamber pressure

The combustion chamber pressure is the same as for natural
gas.
For pressure levels different from those indicated
above, please contact the Technical Office.
WARNING
2.9 Pressure loss diagrams
The gas trains for LPG operation (G31= 24.44 kWh/Sm3) are the
same as those used for natural gas.
The diagrams report the minimum pressure required before the
filter, to have the maximum output with combustion chamber
pressure at 0 mbar.
For the max pressure allowed by the gas train approval, and for
the diagram references see the burner instruction, the gas train
instruction or the instruction manual burner combined with the
gas train.
