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. 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 of the Hydro
Insert and the display will
show
"AL AR- SIC-
FA I L". To restart you need
to reset manually.
Anti-freeze function: if the probe in the Hydro Insert 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 Hydro Insert 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 Hydro Insert display.

Reduction motor:
if the motor stops, the
Hydro Insert continues to
function until the flame 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.
Flue
gas
temperature
sensor: thermocouple that
measures the temperature
of the fumes while keeping
the operation or shuts the
Hydro Insert when the flue
gas
temperature
drops
below the preset value.
Automatic
vent
valve:
this valve eliminates the air
inside the Hydro Insert and
of the heating system.
Electrical
safety:
Hydro Insert 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
Hydro Insert. 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 the Hydro
Insert or plant exceeds 2.5
bar it drains the water from
the circuit.
