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:
ALARMS - MESSAGES
Signalling
Fault
Possible causes
Cures
AL 1
POWER
FAILURE
-The stove does not start.
-No power during the lighting stage
-Turn the stove OFF by pressing the
button P4 and repeat the lighting
procedure.
-Other reinstatement operations must
be carried out by a service centre.
AL 2
FUME
PROBE
-Occurs in case of a fume
temperature probe fault.
-The shutdown procedure is
activated.
-Faulty probe
-The probe is disconnected from the
board.
-Reinstatement operations must be
carried out by a service centre.
AL 3
HOT FUMES
-Occurs if the fume probe detects
a fume temperature above 280°C.
-The shutdown procedure is
activated.
-Faulty tangential fan.
-No power to tangential fan.
-Too many pellets
-Adjust the pellet flow.
-Other reinstatement operations must
be carried out by a service centre
AL 4
FAN FAIL
-Occurs when the fume exhaust
fan is faulty.
-The shutdown procedure is
activated
-The fume fan is blocked.
-Faulty speed control sensor.
-No power to fume fan.
-Reinstatement operations must be
carried out by a service centre.
AL 5
NO IGNITION
-No flame in ignition stage.
-The shutdown procedure is
activated.
-The pellet hopper is empty.
-The electrical element is faulty, dirty
or not correctly positioned.
-Pellet load setting incorrect. .
-Check pellets in hopper.
-Check the lighting procedures.
-Other reinstatement operations must
be carried out by a service centre.
AL 6
NO PELLETS
-Brazier not fed with pellets.
-The pellet hopper is empty.
-The pellet feed gearmotor has to
adjust.
-The gearmotor does not feed pellets.
-Check pellets in hopper.
-Adjust the pellet flow
-Other reinstatement operations must
be carried out by a service centre.
AL 7
THERMAL
SAF
--Occurs in case of cutting in of
auger duct temperature or heating
chamber water temperature safety
thermostat.
-The system is stopped.
-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.
-Check the cause of excessive
overheating.
-Reset the relevant safety thermostat
by pressing the reset button.
AL 8
NO NEG
PRESS
-In the work stage the stove detects
a pressure below the vacuum
switch setting threshold.
-The system is stopped.
-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.
-Check cleanness of the fume duct and
combustion chamber.
-Check hermetic closing of the door.
-Check closing of the overpressure
valves.
-Other reinstatement operations must
be carried out by a service centre.
AL 9
INSUFF
DRAUGHT
-Appears when the combustion air
flow is below a certain threshold.
-The combustion chamber is dirty.
-The fume duct is obstructed.
-The fire door is not closed.
-The overpressure valves are
openstuck.
-Faulty air flow meter.
-Check cleanness of the fume duct and
combustion chamber.
-Check hermetic closing of the door.
-Check closing of the overpressure
valves.
-Other reinstatement operations must
be carried out by a service centre.
AL E
WATER
PRESSURE
-Occurs when the water pressure
does not come within the values for
correct operation.
-The system is stopped.
-Occurs when the pressure transducer
on the water circuit detects a pressure
below 0,6 bar or above the fixed limits.
-Check the cause of the problem,
restoring the circuit pressure by bringing
it to the normal operating value.
