Supply pressure
The supply pressure must lie between the following values:
for natural gas:
For LPG:
The supply pressure is measured as pressure in the gas flow at the measuring
nozzle of the gas valve.
The boiler must not be started up when the supply pressures are outside the said
range. The gas supply company should be informed.
