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-fi replace down if the
temperature is too high or too low.
Flow sensor
Located in the suction channel, it stops the thermal fi replace
when the combustion air fl ow is not correct, which could result
in negative pressure problems in the smoke circuit.
Feed Screw safety thermostat
Placed near the pellet hopper. It disconnects the electrical supply
to the gear motor if the temperature detected is too high.
Water temperature detector
It reads the water temperature in the boiler-fi replace and sends
the circuit board information for pump management and boiler-
stove power modulation. If the temperature is too high, it
starts a shutdown.
Water overheating safety thermostat with manual reset
measures the temperature of the water inside the boiler-fi repla-
ce.
If the temperature is too high, it cuts off the motor's electrical
power supply.
If the thermostat is tripped, it must be reset using the button
located inside external door on the top left part (fi g. B).
Resistance
It sets off of the combustion of the pellets and it remains lit until
the fl ame has been ignited.
Smoke extractor
"Pushes" the smoke into the fl ue and draws out combustion air
via a vacuum.
Gear motors
Activates the feed screw, which allows the pellets to be tran-
sferred from the hopper to the combustion chamber.
Pump (circulator)
"Pushes" water toward the heating system.
Closed expansion tank
"absorbs" the variations in the volume of water contained insi-
de the boiler-fi replace 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.
N.B.:
IF THE BOILER-FIREPLACE BLOCKS, THE REASON WILL APPEAR ON THE DISPLAY AND THIS WILL BE
SAVED.
Overpressure valve
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.
Manometer (M)
Located inside the lower panel (fi g. A), it allows reading the
water pressure inside the thermal fi replace. The maximum re-
commended pressure is 1,5 bar when the boiler-fi replace is on.

2 relief valves:
Located on the upper part, these allow for releasing any air
present while the water is being loaded into the boiler-fi replace.
ATTENTION:
venting the boiler through the appropriate valves (V - photo
above), water leaving may fall on the circuit board or other
electrical components, creating a hazard to persons and product
malfunction. Always direct the "adjustable" valve exhaust
forward and make sure that water does not run over electrical
components.
Discharge valve
Located inside the lower panel; this is to be opened if the water
inside the thermal boiler-fi replace must be emptied.
