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 described below.
b
Adjustments to maximum power must be performed in
the indicated 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 -
2
).
- Turn a water tap on fully, bring the temperature selector to
the maximum and connect the boiler to a power supply.
