System pressure safety
The system pressure is checked electronically and needs
to be between 0,5 and 2,3 bar. If this is not the case, the
pellet boiler signalises an alarm and shows the words
“
A l a r P r e s s
” on the display.
Press” on the display. Check the system pressure keeping
the key pressed for some seconds. You will read the
bar value on the display.
The safety valve keeps anyway the value under 2,5 bar
letting the exceeding water flow out automatically.
Failed light-up
If the flame does not light up during the switching on or if the smokes temperature does not reach a suitable value in
the foreseen time gap, the boiler switches off and you will read the words
“
A l a r N o A c c
on the display.
Press the key “On/Off” to reset the alarm. Wait until the cooling phase is completed, clean the brazier
and start a new light-up.
Switching off while working
The boiler suddenly switches off while working (for example because it has run out of pellets in the tank or
because the motor reducer for pellets loading got broken). The boiler continues working until the pellets left in the
brazier ends. You will then read the words “
A l a r N o F i r e
” on the display and the boiler switches off.
Press the key “On/Off” to reset the alarm. Wait until the cooling phase is completed. Clean the brazier and start a
new light-up.
These alarms remind you that the brazier must be cleaned and installed correctly before switching on
the boiler.
There is no power supply
In the event of a power drop longer than one minute, the boiler can exhaust some smoke in the room: this causes
no risks. As soon as you have the power supply again, the boiler will have the words “
C o o l F i r e
” on the display.
After completing the cooling phase, the boiler will start up again automatically according to the previous settings.
Failure on electrical devices
Manual restart thermostat
Do not attempt to start the boiler before the required time or it may get blocked.
If this occurs, switch off the switch on the back of the pellet boiler for 1 minute,
set it on again and wait 10 minutes before starting the boiler again.
The power socket where the boiler is connected should be fitted with “earth
connection complying with regulations in force.” The Manufacturer shall not
be held responsible for damage to things or people resulting from negligent
installation.
