16. SECURITY MEASURES
Furnace is equipped with following safety devices:
-PRESSURE REGULATOR
Controls the pressure in the chimney. It stops transport spiral for the pellet when the outlet is clogged or when it
faces pressure (draught)
-FLUE GASES TEMPERATURE SENSOR
Measures the temperature of the flue gasses and allows furnace ignition o stops it if the flue gasses temperature
goes bellow set value.
-CONTACT THERMOSTAT IN THE FIREBOX OR ON THE SCREW FEEDER CASE
When a temperature exceeds safety values, furnace immediately shuts down.
- CONTACT THERMOSTAT IN THE BOILER
When a temperature exceeds safety values, furnace immediately shuts down
-WATER TEMPERATURE SENSOR
When water temperature gets close to 85ºC, sensor runs cooling cycles or automatically shuts the furnace down
using “ECO-STOP” option, in order to avoid blocking the temperature sensor.
-ELECTRICAL SAFETY
Furnace is protected from power surges with standard fuse located on control panel on the rear side of the furnace.
Rest of the fuses are located on the rear side of the furnace in order to protect motherboard (integrated cards and
heat exchanger cards).
-FLUE GASSES FAN
If the ventilator stops, motherboard blocks the pellet feed and emits alarm signal.
-HELICAL GEARED MOTOR
When helical geared motor stops working, furnace continues to work until the flame does not extinguish and until
the minimum cooling level is not reached.
-TEMPORARY OUTAGE
After short outage, furnace automatically starts cooling process.
-NO IGNITION
If during ignition there is no flame, furnace automatically changes to alarm status.
