GAS TRAIN
The gas trains for LPG functioning are the same as those used
for methane gas.
For the maximum standardised pressure of the valves, see the
burner or gas train instructions.
The adjacent table shows minimum pressure losses along the
gas supply line depending on the maximum burner output opera-
