They show the gas pressure in mbar, (in points Pi and Pt of the gas threaded connection), necessary to obtain a
certain capacity in m3/h. The pressures are set with the burner working and are meant with the combustion chamber
set at 0 mbar. If the chamber is in pressure, the necessary gas pressure will be the one of the diagram plus the value
of the pressure in the chamber.
