• COMPONENTS - SAFETY AND DETECTION DEVICES
Smoke thermocouple
on the smoke outlet. It reads the smoke temperature. It regula-
tes the ignition stage and shuts the boiler- replace down if the
temperature is too high or too low.
Flow sensor
positioned in the aspiration channel, the sensor stops the boiler
when the ow of comburent air is incorrect (and which could
cause the consequent risk of depression problems in the fumes
circuit).
Feed Screw safety thermostat
Placed near the pellet hopper. It disconnects the electrical sup-
ply to the gear motor if the temperature detected is too high.
Water temperature detector
It reads the water temperature in the boiler and sends the circuit
board information for pump management and boiler power
modulation.
If the temperature is too high, it starts a shutdown.
Water overheating safety thermostat
detects the water temperature in the thermo-stoves. If this is
too high, it triggers the shutdown process by disconnecting the
electrical supply to the gear motor.
In the event that the thermostat has been operated, it must be
re-activated by acting on the reset button behind the thermo-
stove (see page. 28).
Overpressure valve 3 bar
Upon reaching the pressure stipulated on the plate, the system
is triggered to discharge the water and consequently the water
must be topped up.
WARNING!!!! remember to carry out the connection with
the sewage system.
Electrical resistance
It sets off of the combustion of the pellets and it remains lit until
the ame has been ignited.
This component is subject to wear.
Smoke extractor
"Pushes" the smoke into the ue and draws out combustion air
via a vacuum.
Vacuum gauge (electronic pressure sensor):
positioned on the smoke extractor, which detects the vacuum
value (compared to the installation environment) in the combu-
stion chamber.
Tank safety thermostat:
Located on the system that loads the pellets from the hopper.
Trips when the temperature inside the boiler-stove is too high.
It stops pellet loading, causing the boiler-stove to go out.
N.B.:
IF THE BOILER-STOVE BLOCKS, THE REASON WILL APPEAR ON THE DISPLAY AND THIS WILL BE SAVED.
FEATURES
Pump (circulator)
"Pushes" water toward the heating system.
Closed expansion tank
"absorbs" the variations in the volume of water contained insi-
de the boiler-stove due to the heating effect.
Aheating technician must evaluate the need to add a second
tank to the existing one, depending on total amount of wa-
ter in the system.
Gear motors
activates the feed screw, which allows the pellets to be transfer-
red from the hopper to the combustion chamber.
Manometer
located on the rear left side, it allows you to read the water
pressure in the thermal stove.
With the thermal stove running, the recommended pressure is
1,5 bar.
Drain tap
placed inside the lower part of the thermal stove. This is to be
opened if the water inside the thermal stove must be emptied.
Venting valve:
positioned in the upper part (see page. 35), it allows for the
"bleeding" of any air present during the loading of water inside
the boiler-stove.
