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 Description
Water temperature thermostat If the water temperature exceeds the set safety value, it immediately stops the pellet load-
ing 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.
Pressure switch 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.
Limit switch for closing combustion
chamber door, ash drawer and pellet
hopper lid
If the door of the combustion chamber, the ash drawer or the pellet hopper lid are not
properly closed, it immediately stops the pellet loading motor; if they are not closed within
60 seconds, the stove switches off automatically.
Safety valve for water overpressure In the event of overpressure of the hydraulic system, the safety valve opens discharging
water, so that the stove is not damaged.
Electrical safety 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.
It should be noted that the stove’s operating program has been designed to stop stove operation in the event of malfunctions:
Anomalies Description
Temperature in the combustion cham-
ber
If the temperature probe in the combustion chamber detects temperatures that are too
high or too low, the stove is switched off and the relative alarm is displayed.
Flue gas temperature 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.
Water over-temperature 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.
Water pressure 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.
Smoke fan break If the fan stops, the electronic board blocks the supply of pellets and the alarm is displayed.
Gear motor failure If the gear motor stops, the appliance switches off safely.
Temporary power failure 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.
No ignition If no flame develops during the ignition phase, the stove goes into alarm.
⚠
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.
