Pressure loss
The gas train pressure loss p is provided from the diagram (Fig.
7); the scales of the volumetric output
for:
a
air,
n
natural gas (G20),
p
propane (G30),
c
town gas (G140), only for applications not covered by the
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
losses (see burner manual) and the back pressure of the com-
bustion chamber (see heat generator manual).
