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.
Adjustments to maximum power must be performed in the indi-
cated sequence and only by qualifi ed technicians.
- Remove the casing by loosening the screws holding it in place(A) (see
section 6 "Removing the casing").
- Loosen the pressure tapping point screw (1) located downstream of the
gas valve by approximately two turns and connect a pressure gauge
there.
- Disconnect the compensation inlet (5) from the gas valve.
- Remove the protective cap (2).
- Turn a water tap on fully, bring the temperature selector to the maximum
