GAS TRAIN PRESSURE LOSSES
The gas train pressure loss ∆p is provided from the diagram; the scales of the volumetric output
valid respectively for:
a = air
n = natural gas (G20)
p = propane (G30)
c = city gas (G140), only for applications not covered by the Gas Appliances Directive (90/396/EEC).
The value, provided from the diagram, can be different according to the pressure stabilizer adjustment.
The minimum necessary pressure in the network can be obtained by adding the pressure of the diagram
to the burner pressure losses (see the burner technical instruction) and the back pressure of the com-
bustion chamber (see the technical instruction of the heat generator).
