Failed ignition
To turn the stove back on, reset the alarm by keeping the power button on the handheld (or on the electronic card) pressed until
the acoustic signal is heard and then switch on again.It is not necessary to remove any unburnt pellets inside the brazier. In fact, as
soon as the user reboots the stove, the system tries to ignite any fuel left in the brazier before starting the loading phase.
TROUBLESHOOTING
Alarm management
Alarms are indicated by an acoustic signal (if activated) and a message on the control panel. In case of an alarm the shutdown
procedure is automatically activated. Cancel the signal by pressing button P3 on the remote control or the emergency panel and
wait for the insert to reach OFF status. Eliminate the cause and restart the insert according to the normal procedure described in this
manual. Listed below are the alarms that can appear on the control panel, with the causes and cures:
Signalling
AL 1 -The stove does not start.
POWER
FAILURE
AL 2 -Occurs in case of a fume
FUME temperature probe fault.
PROBE -The shutdown
activated.
AL 3 -Occurs if the fume probe detects
HOT FUMES a fume temperature above 280°C.
-The shutdown
activated.
AL 4 -Occurs when the fume exhaust
FAN FAIL fan is faulty.
-The shutdown
activated
AL 5 -No flame in ignition stage.
NO IGNITION -The shutdown
activated.
AL 6 -Brazier not fed with pellets.
NO PELLETS
AL 7 --Occurs in case of cutting in of
THERMAL auger duct temperature or heating
SAF chamber water temperature safety
thermostat.
-The system is stopped.
AL 8 -In the work stage the stove detects
NO NEG a pressure below the vacuum
PRESS switch setting threshold.
-The system is stopped.
AL 9 -Appears when the combustion air
INSUFF flow is below a certain threshold.
DRAUGHT
AL E -Occurs when the water pressure
WATER does not come within the values for
PRESSURE correct operation.
-The system is stopped.

ALARMS - MESSAGES
Fault
-No power during the lighting stage
-Faulty probe
-The probe is disconnected from the
procedure is board.
-Faulty tangential fan.
-No power to tangential fan.
procedure is -Too many pellets
-The fume fan is blocked.
-Faulty speed control sensor.
procedure is -No power to fume fan.
-The pellet hopper is empty.
procedure is -The electrical element is faulty, dirty
or not correctly positioned.
-Pellet load setting incorrect. .
-The pellet hopper is empty.
-The pellet feed gearmotor has to
adjust.
-The gearmotor does not feed pellets.
-The safety thermostat has detected
a temperature above the setting
threshold due to overheating of the
bottom part of the hopper or the
heating chamber water, blocking
gearmotor operation.
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure valves are open-
stuck.
-Faulty vacuum switch.
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure
openstuck.
-Faulty air flow meter.
-Occurs when the pressure transducer
on the water circuit detects a pressure
below 0,6 bar or above the fixed limits.
