Pressure loss
The gas train pressure loss p is provided from the diagram (Fig.
6); the scales of the volumetric output
for:
air,
a
natural gas (G20),
n
propane (G30),
p
town gas (G140), only for applications not covered by the
c
Gas Appliances Directive (2009/142/EC).
The values, provided from the diagram, can be different accord-
ing to the pressure regulator calibration.
The minimum necessary pressure in the network can be obtained
by adding the pressure of the diagram to the burner pressure
