WHAT HAPPENS IF..
…the pellet does not ignite
With no ignition. The
“NO IGNIT-“
alarm message appears.
Cancel the alarm and bring the boiler to standard condition by pressing key 4 for a few seconds.
...the fire door is open or closed improperly
In case the door is open or closed improperly, the motor reducer cannot be powered electrically, not
allowing the boiler to switch on. If the fire door is opened during the normal functioning, the boiler
burns all the pellet in the brazier, activating the
“NO PELLET”
alarm (sudden switch off).
...the flue is dirty, blocked or not manufactured correctly
In case the flue is dirty, blocked or not manufactured correctly, the motor reducer cannot be powered
electrically not allowing the boiler to switch on. If the flue blocks during the normal operation, the
boiler burns all the pellet in the brazier, activating the
“NO PELLET”
alarm (sudden switch off).
...the boiler is overheated
The motor reducer is not electrically powered with water in boiler over-temperature as the thermostat
intervenes in manual re-arm. If it happens with boiler working, this goes in
“NO PELLET”
alarm
(sudden switch-off). Therefore the thermostat must be rearmed before switching on the boiler.
...lack of power (black out)
If power is missing for a time less than Pr48, when restored the boiler immediately re-starts from
operative state it had before power outage (recovering the set work power).
If power is missing for a time greater than Pr48, when restored the boiler is placed at
“STOP FIRE”
(stand-by) mode
and carries out the entire switch off cycle until it cools down. Once this phase is
completed, the boiler can be normally switched on to proceed working at the set power.
