10 - SAFETY DEVICES AND ALARMS
SAFETY DEVICES
The product is supplied with the following safety devices:
SMOKE PRESSURE GAUGE
Monitors pressure in the smoke duct. It is designed to shut down the boiler in the event of an obstructed flue or significant back-pressure
(from the wind).
WATER PRESSURE GAUGE
Check that there is sufficient pressure in the hydraulic system.
OVERPRESSURE VALVE
Discharges water from the system in the event of overpressure.
Attention! Can emit hot liquid which is ducted.
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset
value.
CONTACT THERMOSTAT IN THE FUEL DUCT
If the temperature exceeds the preset safety level, it immediately shuts down the running of the boiler.
WATER CONTACT THERMOSTAT
If the temperature exceeds the preset safety level, it immediately shuts down the running of the boiler.
WATER TEMPERATURE SENSOR
When the water reaches the stop temperature (85°C) the sensor signals to the boiler to turn off and go into standby automatically.
ELECTRICAL SAFETY
The boiler is protected against violent changes in current by two main fuses which are located in the start switch at the back of the boiler.
Other fuses that protect the electronic boards are found on the latter.
SMOKE FAN
If the fan stops, the electronic board shuts off the supply of pellets in good time, and an alarm message is displayed.
GEAR MOTOR
If the reduction motor stops, the boiler will continue to run until the flame goes out due to lack of fuel and until a minimum level of
cooling is reached.
TEMPORARY POWER CUT
When a power cut is less than 10" the boiler returns to its previous operating state; if it is more, it executes a cooling/re-ignition cycle.
FAILED START-UP
If during ignition the preset smoke temperature is not reached, the boiler will go into alarm condition.
ANTI-FREEZE FUNCTION
If the probe in the boiler detects a water temperature of less than 5°C, the circulation pump is automatically activated to keep the system
from freezing.
PUMP ANTI-SEIZURE FUNCTION
If the pump is not used for prolonged periods, it is activated periodically for a few seconds to keep it from seizing up.
