Topping-up the system with water
The water pressure in the central heating circuit must be
checked during the entire period of operation of the boiler.
In this respect, the reading on the pressure gauge M (fig.
2), located on the lower part of the boiler, must not be less
than 1 bar.
If there is insufficient water in the boiler, the code H2O will
flash on the display (see fig 2).
To bring the system back up to pressure, open the
external filling tap R (fig. 2) and use the pressure gauge M
(fig. 2) to check that the systems pressure reaches the
middle of the green area (equal to 1,2 bar, see fig. 3) and
that the code H2O lights up.
When the operation is complete, close the fill tap.
Diagnostics – Error codes:
This paragraph contains a list of error codes that the boiler
may generate on the display 8 (see “Control panel”)
together with the relative indications and the operations
that the user can carry out to reset the boiler.
If the problem re-occurs after the following
actions have been taken, call an authorised

Check the water pressure in the central heating circuit. The reading on the pressure gauge M (see fig. 3),
located on the lower part of the boiler, must not be less than 1 bar .
If the pressure is less than 1 bar, top-up the system as described in paragraph “Filling the system”.
The boiler will restart automatically.
If the problem persists, Call the Service Centre.
