4.3.2 Startup stage
To light the stove, press the button 'P4' for 3 seconds: the message 'START' will appear on the display.
This stage is automatic and managed entirely by the electronic controller without the possibility of changing the
parameters.
Alternatively the stove can be lit by pressing the buttons P4 and P5 together for 3 seconds. The message
AWAITING REQUEST appears on the display. With this mode the stove switches to standby status and carries out
the lighting-start stage only if a request for heat is recognised, e.g. to heat the water or for DHW (if available).
Dialogue box
The stove carries out the startup stages in sequence
according to the procedures defined by the
parameters that manage levels and times, reaching
the work condition unless anomalies or alarms
occur, according to the following table:
After a certain time has elapsed, if the fume temperature has not reached the permissible minimum value the stove
goes in alarm status.
- Do not use flammable liquids to light the unit.
- In case of persistent failed lighting, contact the Service Centre.
