AND TROUBLESHOOTING

BOILER SHUTDOWN

The boiler unit is equipped with safety devices which intervene in

certain situations to shutdown the boiler.

Some of these situations are signalled by the unit and can be corrected

by the user.

SHUTDOWN DUE TO THE FAILURE OF THE

BURNER TO LIGHT AUTOMATICALLY

This anomaly is indicated by the red “B” L.E.D.

To reset the unit, press and then release the “A” button.

At this point, the electronic ignition system will attempt to light the

burner again.

If lighting failure occurs repeatedly, it is recommended that you contact

one of our Authorised Service Centres.

SHUTDOWN DUE TO OVERHEATING

This anomaly is signalled by the red “G” L.E.D.

The boiler shuts off because the safety thermostat detected that the

boiler temperature has reached the temperature limit.

To reset the unit, wait until the boiler has cooled and then press the “A”

button.

If the safety thermostat shuts off the unit on a frequent basis, contact

one of our Authorised Service Centres for assistance.

SHUTDOWN DUE TO INSUFFICIENT

WATER CIRCULATION

This anomaly is indicated by the red “D” L.E.D.

One of the possible causes of this shutdown situation could be the lack

of water in the boiler or water circulation failure in the primary heating

circuit.

Check the system pressure on the pressure gauge “O” and, if it is less

than 0.5 bar, consult your installer for checking and refilling the system.

Then reset the unit by turning the boiler off and then back on with the

On/Off button “L”.

If this situation persists, contact one of our Authorised Service Centres.
