Failure on electrical devices
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 stove switches off and you will
read the words "Alar No Acc" 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 stove 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 stove
continues working until the pellets left in the brazier ends.
You will then read the words "Alar No Fire" on the display and
the stove 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 cle-
aned and installed correctly before switching on the
stove.
There is no power supply
In the event of a power drop longer than one minute, the
pellet boiler stove can exhaust some smoke in the room:
this causes no risks.
As soon as you have the power supply again, the pellet boi-
ler stove will have the words "Cool Fire" on the display. After
completing the cooling phase, the stove will start up again
automatically according to the previous settings.
CAUTION!
do not attempt to start the pellet boiler stove before the
required time or it may get blocked.
If this occurs, switch off the switch on the back of the
pellet boiler stove for 1 minute, set it on again and wait
10 minutes before starting the stove again.
Electrical safety
In the event of an electrical shock (lightning), the pellet boi-
ler stove is protected by a fuse 2,5 A 250V which is placed
on the back of the stove near the cable for power supply.
Extract its box and replace the fuse.
CAUTION!
the power socket where the pellet boiler stove is con-
nected should be fitted with "earth connection com-
plying with regulations in force." The Manufacturer
shall not be held responsible for damage to things or
people resulting from negligent installation.
Smokes exhaust safety
A mechanical depressor checks the correct depression for
a proper smokes exhaust. On the contrary, if the flue is ob-
structed, the pellet boiler stove switches off and you will
read the words "Alar Dep Fail" on the display.
Pellets temperature safety
In the rare event there is a too high temperature in the tank,
the thermostat for pellets safety with manual reset creates
an alarm (Alar Sic Fail) stopping the pellet boiler stove. You
need to reset the system working on the device placed on
the back of the stove (Pict. 5)
Water temperature safety
In the event the water temperature exceeds a limit value of
100°C, the thermostat for water safety lets the stove switch
off. You will read the words "Alar Sic Fail" on the display. Once
you have waited a minimal time required for water cooling,
you need to reset the thermostat placed on the back of the
stove (fig. 5).

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 stove signalises an alarm and shows the words "Alar
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 let-
ting the exceeding water flow out automatically.
