Safety devices

The stove has been designed and equipped with safety systems to minimize user risks.
It is equipped with the safety devices listed in the following table, which also intervene in case of failure of the electronic board.
Element
Water temperature thermostat
Pellet tank thermostat
Pressure switch
Safety valve for water overpressure
Electrical safety
It should be noted that the stove's operating program has been designed to stop stove operation in the event of malfunctions:
Anomalies
Flue gas temperature
Water over-temperature
Water pressure
Smoke fan break
Gear motor failure
Temporary power failure
No ignition
⚠
It is forbidden to tamper with the safety devices. Restarting the product is only possible after eliminating the cause that
caused the intervention of the safety system. To understand which anomaly occurs, consult this manual which explains,
⚠
depending on the alarm message that the device displays, how to intervene on it.
If the problem persists, contact the Support Service.

Description
If the water temperature exceeds the set safety value, it immediately stops the pellet
loading motor and the stove is automatically switched off; to restart it, it is necessary to
wait until it has cooled down and manually reset the thermostat, using the appropriate
button.
If the temperature exceeds the set safety value, it immediately stops the pellet loading
motor and the stove is automatically switched off; to restart it, it is necessary to wait until
it has cooled down and manually reset the thermostat, using the appropriate button.
If the pressure in the smoke outlet duct is too high (a sign that the smoke evacuation sys-
tem is obstructed) it immediately stops the pellet loading motor and the stove switches off
automatically.
In the event of overpressure of the hydraulic system, the safety valve opens discharging
water, so that the stove is not damaged.
In case of failure of the electrical components or wiring, the fuse and grounding keep the
appliance safe. It is necessary that the electrical system of the house is up to standard,
equipped with a grounding circuit and all the safety systems required by the standards.
Description
If the temperature probe at the smoke outlet detects temperatures that are too high, the
stove is switched off and the relative alarm is displayed.
If the water temperature in the boiler of the stove, detected by the appropriate probe, is
too high, the stove is switched off and the relative alarm is displayed.
If the water pressure in the boiler of the stove, detected by the pressure transducer, is too
high or too low, the stove is switched off and the relative alarm is displayed.
If the fan stops, the electronic board blocks the supply of pellets and the alarm is dis-
played.
If the gear motor stops, the appliance switches off safely.
If a power failure occurs during operation, when the power returns the temperature in the
combustion chamber is checked and, if necessary, the stove goes into cooling mode.
If no flame develops during the ignition phase, the stove goes into alarm.
