WARNING : If the value displayed is different from the one
shown in the section “5.3 Technical data” DO NOT MAKE ANY
ADJUSTMENT ON THE GAS VALVE, please contact the Technical
Assistance Centre.
9
WARNING : The gas valve DOES NOT REQUIRE ADJUSTMENTS and
the possible tampering can cause a malfunction or failure of
the boiler which may result in substantial property damage,
severe personal injury or death.
NOTICE : When the combustion analysis function is in progress
all the heat requests are inhibited and a scrolling message
appears at the foot of the main page of the front control.
When the checks are completed:
- set the boiler to “DHW” or “CH&DHW” mode
- regulate the heat request temperature values according
to the customer’s needs.
IMPORTANT
The combustion analysis function is active for a time
limit of 15 minutes; the burner shuts down if an outlet
temperature of 203°F (95° C) is reached. It will ignite again
when the temperature falls below 167°F (75° C).
9
In case of a low temperature system we recommend carrying
out the efficiency test, setting the boiler STATE to DHW mode,
opening the hot water tap to full capacity and setting the
temperature of the domestic hot water to the maximum.
11.22 Lights and faults
In the unlikely event of boiler fault, the appliance will enter a
final or temporary fault condition, whereby it will shut down
and a
WARNING triangle will appear on the left side of the UI
screen. Use the arrow buttons on the user inferface to navigate
to the WARNING triangle, and press “ENTER”. Then follow the
instructions/advice as shown on the user interface screen.

The faults description screen is automatically displayed once the
display illumination time has elapsed without any button being
pressed.
Press the “up” and “down” buttons to display the descriptions
of any other faults that may be present.
Reset function
In order to reset the boiler’s operation in the event of a fault, it
is necessary to access the fault description screen. If the lockout
is of a non-volatile type that requires a reset procedure, this will
be indicated on the screen, and can be performed by pressing
the “ENTER ” button on the front control.
At this point, if the correct operating conditions have been
restored, the boiler will restart automatically.
There are a maximum of 3 consecutive attempts at a release
by the front control, should it go through all 3 attempts to reset
the fault, the appliance will need to be disconnected briefly
from the electrical supply in order to carry out any further reset
attempts. Once the electrical supply has been restored, further
attempts at reset can be carried out.
