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
flue or significant back-
pressure in the presence
of wind, of the door of
the combustion chamber
or open fault extractor
fumes. At the time of the
pressure switch will show
" " A L A R - DE P- FA IL A L A R - DE P- FA IL" " .
RESTART
WATER
Safety thermostat
with manual reset
for the water
temperature: if the
temperature of the water
tank exceeds the preset
safety level of 100 °C
immediately stops the
operation of the boiler
and the display will show
" " A L A R - S I C - F A I L A L A R - S I C - F A I L " " .
restart you need to reset
manually.
Anti-freeze function: if the probe in the boiler detects a water temperature of less than 6°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

Reduction motor: if
the motor stops for

the boiler continues to
function until the flame
goes out for lack of fuel,
and until It has cooled
down to the minimum
level.
Smoke pressure
switch: it controls the
pressure in the smoke
duct. It blocks the pellet
loading auger in case
the drain is blocked or
there are significant

Flue gas temperature
sensor: thermocouple
that measures
temperature of
fumes while keeping the
operation or shuts the
boiler when the flue gas
temperature drops below
the preset value.
Automatic vent valve:
this valve eliminates the
air inside the boiler and
of the heating system.
the
Electrical
the Boiler is protected
the against violent surges of
the current (ex. lightnings)
by the main fuse 4 A
which is located on the
control panel at the rear
of the boiler. Other fuses
to protect the electronic
boards are to be found on
the boards themselves.
Safety valve:
valve acts to prevent
over pressurization of the
hydraulic system.
If the pressure of the boiler
or plant exceeds 2,5 bar it
drains the water from the
circuit.
