EN
If a certain vacuum value is not reached or the fume outlet is blocked or
the fire door is open, the safety pressure switch detects the lack of negative
pressure inside the combustion chamber which, via the electronic control,
stops the auger rotation motor, alerting the user of the fault with a message
on the control panel "AL8 NO NEG PRESS".
Any and/or sudden overpressures of the combustion fumes inside the
chamber and the fume evacuation ducts are discharged through opening of
the safety valve located above the combustion chamber.
A temperature probe connected to a safety thermostat is positioned on the
pellet conveyor which automatically deactivates the pellet feed in case of
excessive heating > 85°C. In this case the extractor and/or fans continue to
operate, allowing the unit to cool rapidly. The fault is shown on the control
panel with the message "AL 7 THERMAL SAFETY". In case of intervention,
operate as follows:
▪ Allow the unit cool down for at least 45 minutes and reset the thermostat
by pressing the button on the right-hand side, after unscrewing the
protective cap.
▪ Check that the power is present and restart the unit as per normal startup.
The solutions that prevent flare-back are:
▪ negative pressure in the combustion chamber.
▪ the siphon shape of the pellet chute.
▪ the hopper temperature thermal safety.
The unit is protected against overcurrent by a 2A fuse inserted into the power
supply, mounted in its fuse holder and fixed to the rear wall.
If for any reason the fume extraction fan stops, the electronic control instantly
blocks the supply of pellets, showing the message "AL4 FAN-FAILURE".
