Operation shutdown
This type of error is “non-volatile”, which means
that it is not removed automatically (the led

led

will indicate the error code). In this case
the boiler does not restart automatically, but it
may be reset by pressing the Reset button. If
the problem manifests itself again after several
attempts to reset the appliance, contact a
qualifi ed technician.

Important
If this shutdown occurs frequently, contact
an authorised service centre for assistance.
For safety reasons, the boiler will allow a
maximum of 5 reset operations to take place
in 15 minutes (individual presses of the
button).
If the shutdown is occasional or an isolated
event, this is not a problem.
Temporary Shut-Off due to defective fl ue
gas discharge
This device causes the boiler to shut down in the
event of an anomaly in the fl ue gas discharge.
The appliance shutdown is temporary and is
signalled by the yellow led
“5”
.
After 12 minutes, the boiler begins the ignition
procedure; if normal conditions have been
restored, the boiler operates as normal. If not,
the boiler shuts down and the cycle is repeated.
WARNING
In the event of a malfunction or if repeated
intervention is required, switch the boiler
off , shut off the electricity supply by turning
the external switch to the OFF position and
shut off the gas valve. Contact the Technical
Assistance Service or a qualifi ed technician
in order to repair the fl ue gas discharge
fault once the cause of the malfunction is
detected.
Whenever maintenance work is performed
on the device, use original spare parts only
and follow the relative instructions carefully.
This device must never be shut down as this
may jeopardise the safety of the user.
