3. IGNITION AND SHUT-DOWN
3.01 Ignition
Place the boiler thermostat in 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);
• adjust, using the knob, 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.).
Note
If after having correctly performed the ignition operation, the burners do not light and the reset button light
on the electronic control unit (11 - Fig. 1) is on, wait around 10 seconds and then press the reset button. The
control unit is reset and will repeat the ignition cycle.
Note
In the event of power failure, the burners will shut-down and will be automatically ignited once the power
returns.
3.02 Temporary shut-down
To temporarily shut-down the boiler, simply place the boiler switch (10- Fig. 1) in position ”0”.
3.03 Extended boiler shut-down
To shut the boiler down, proceed as follows:
• turn the knob of the boiler switch to position ”0”;
• close the gas cock upstream from the boiler;
• disconnect power to the appliance.
Note
If the boiler is not used for an extended period in winter, to avoid damage from frost, special anti-freeze
should be added to the system, or else the system should be completely emptied (operation to be performed
only by qualified personnel).
3.04 Adjusting the central heating supply temperature
The supply temperature can be set using the boiler thermostat. The field of adjustment for the knob (1 - Fig. 1)
is 30-90 °C. It is not recommended to set the temperature below 50°C, to avoid dangerous condensation from
occurring.
