Supply Pressure
The supply pressure must lie between the following values:
for natural gas: - min. 18,0 mbar
- max. 25.0 mbar
For LPG: - min. 42,5 mbar
- max. 57,5 mbar
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.
