5.5 IGNITION CYCLE.
The ignition sequence is carried out in two different ways depends if it is working on sanitary or heating
mode:
 SANITARY if required the ignition cycle is repeated 3 times:
1st attempt with the power of slow ignition, if at the end of the safety time (8 sec) the flame has not been
detected it will be signalled 5 P1 and a second attempt will be made;
2
nd
attempt with the power of slow ignition, if at the end of the safety time (8 sec) the flame has not been
detected it will be signalled 5 P2 3
rd
attempt will be made ;
3
rd
attempt with the power of slow ignition, if at the end of the safety time (8 sec) the flame has not been
detected it will be shutdown 5 01 c with 40 seconds of post-ventilation at maximum speed and 2
minutes of post-circulation at minimum speed.
 HEATING if required the ignition cycle is repeated 3 times:
1st attempt with 80% of the power of slow ignition, if at the end of the safety time (8 sec) the flame has
not been detected it will be signalled 5 P1 and a second attempt will be made;
2
nd
attempt with 90% the power of slow ignition, if at the end of the safety time (8 sec) the flame has not
been detected it will be signalled 5 P2 3
rd
attempt will be made;
3
rd
attempt with the power of slow ignition, if at the end of the safety time (8 sec) the flame has not been
detected it will be shutdown 5 01 with 40 seconds of post-ventilation at maximum speed and 2 minutes
of post-circulation at minimum speed.
5.6 THE FUME DISCHARGE SYSTEM
On the external part of the boiler there is a fume discharge collector.
