SAFETY DEVICES
The product is supplied with the following safety devices:
PRESSURE SWITCH
Monitors the negative pressure in the smoke duct. It is designed to shut down the pellets feed screw in the event of an obstructed flue or
significant back-pressure.
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the smoke temperature drops below the
preset value.
TEMPERATURE PROBE IN THE FUEL TANK
If the temperature exceeds the preset safety value, it immediately stops product operation, which must cool down. In order to start back
up again, the probe needs to be manually restored. If the stove goes into lockdown again, it is necessary to call the technical assistance
centre.
ELECTRICAL SAFETY
The product is protected against sudden current surges by a main fuse in the power supply panel on the rear part of the product. Other
fuses that protect the electronic boards are found on the latter.
SMOKE FAN FAULT
If the fan stops, the electronic board promptly blocks the supply of pellets and the alarm is displayed.
GEAR MOTOR FAULT
If the gear motor stops, the product continues to work until the minimum cool level is reached.
TEMPORARY POWER CUT
If a power cut occurs during operation, the product automatically sets itself in cooling mode when the power is restored and then restarts.
FAILED START-UP
If no flame is developed during start-up, the product will go into alarm status.
IT IS FORBIDDEN TO TAMPER WITH THE SAFETY DEVICES.
The product can be started-up and the automatic function of the probe restored only after having eliminated the cause that
triggered the safety system. This manual will help you understand which anomaly has occurred, and explain how to intervene
according to the alarm message displayed on the product.
