As described above, the boiler is set up to operate on natural gas (G20); gas pressure has been tested
and calibrated by the manufacturer.
However, due to possible differences in pressure in the gas supply system, at first startup you should
check and if necessary adjust the pressure at the injectors to match the pressure level shown in table
3 (paragraph 2.02) of the technical data.

Adjust the supply pressure at the main burners by turning the stabilizer screw 7 (fig. 7).
To increase the pressure, turn the screw clockwise. To decrease the pressure, turn the screw
anticlockwise.
The pilot light requires no adjustment.
