10.01 fi rst ignition
The first ignition and the training of the user for the correct operation of the boiler must be carried out by an
authorised service centre.
10.02 checks to be performed upon fi rst ignition
During the first ignition of the boiler, it is important to check that the on-off valves between the boiler and the
heating system are open; that the heating circuit is filled and vented of air; that there are no gas or water leaks in
the heating system or in the boiler; that the electrical connections are correct and that the earth cable is connected
to an adequate earth system; that there are no inflammable liquids or materials in the immediate vicinity of the
boiler; and that the flue is not blocked.
10.03 ignition
Set the boiler thermostat to the “minimum temperature” position, and power the appliance using the boiler
switch.
To ignite the burner assembly, proceed as follows:
• Open the gas cock (fitted by the installer);
• Vent the air in the gas pipes using the air vent fitted upstream from the gas valve (fig. 11).
• Adjust the knob on the boiler thermostat to the desired value (not less than 50 °C.).
At this stage the electronic control unit starts operating and will pilot, after a set waiting time, the gas valve and
the spark to the ignition electrode, which in turn will light the burner assembly. The ionisation electrode then checks
the presence of the flame in the burner assembly.
The boiler operates automatically, controlled by the boiler thermostat and/or any other control devices (room
thermostat, electronic temperature control unit, etc.).
