Safety devices

Pressure switch: monitors
depression in the smoke
duct. It is designed to shut
down the pellet feed screw
in the event of an obstructed
fl ue or signifi cant back-
pressure in the presence
of wind. At the time of the
pressure switch will show
"A L A R-D EP -F AIL".
RESTART
WATER
Safety thermostat with
manual reset for the
water temperature:
the temperature of the
water tank exceeds
the preset safety level
of 100 °C immediately
stops the operation
the thermostove and
the display will show
"A L A R-S I C- FA IL". To restart
you need to reset manually.
Anti-freeze function: if the probe in the thermostove 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 10
seconds, to prevent it blocks.
Tampering with the safety devices is prohibited. It is only after eliminating the cause which gave
rise to the intervention of the safety system, that it is possible to relight the stove and thus reset
the automatic operation of the sensor. To understand which anomaly has occurred, consult this
manual at paragraph relating to alarms which explains what to do based on the alarm message the
stove display.

Reduction motor:
if the motor stops, the
thermostove continues to
function until the fl ame goes
out for lack of fuel, and until
It has cooled down to the
minimum level.
Water temperature probe:
if the water temperature
if approaches the blocking
temperature (100 °C), the
probe requires to interrupt
the supply of pellets.
of
Flue gas temperature
sensor: thermocouple that
measures the temperature
of the fumes while keeping
the operation or shuts the
thermostove when the fl ue
gas temperature drops
below the preset value.
Automatic vent valve:
this valve eliminates the air
inside the thermostove and
of the heating system.
Electrical safety:
stove is protected against
violent surges of current
(ex. lightnings) by the main
fuse 4 A which is located
on the control panel at the
rear of the thermostove.
Other fuses to protect the
electronic boards are to
be found on the boards
themselves.
Safety valve: this valve
acts to prevent over
pressurization of
hydraulic system.
If the pressure of
thermostove or plant
exceeds 2.5 bar it drains the
water from the circuit.
