3.10 Setting the appliance
The boiler has already been factory set by the manufacturer.
However, should it need to be readjusted, for example after non-scheduled
maintenance, replacing the gas valve or gas conversion, proceed as de-
scribed below.
b
Adjustments to maximum power must be performed in the indi-
cated sequence and only by qualified technicians.
- Remove the casing as shown in section 6.
- Loosen the pressure tapping point screw (fig. 11 -
1
) located downstream
of the gas valve by approximately two turns and connect a pressure
gauge there.
- Disconnect the compensation inlet (fig. 11 -
5
) from the gas valve.
- Remove the protective cap (fig. 11 -

- Turn a water tap on fully, bring the temperature selector to the maximum
and connect the boiler to a power supply.
