To check the minimum power loosen screw "2"
1.
the pressure gauge fitting pipe in the pressure intake.
2. Disconnect the compensation pipe of the air chamber (fig.B).
3. Have the boiler work on minimum power and disconnect a cable
from the modulator (fig.D). The supply pressure must correspond with
the one foreseen for the type of gas for which the boiler has been
prearranged (refer to table below). If it does not correspond, act on
adjusting screw "4"
"3"(fig.C).
4. After checking tighten screw "2" and check sealing.
5. Reconnect the cable of the modulator.
6. Reconnect the compensation pipe
