• 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.
Mechanical pressure switch
The pressure switch stops the supply of pellets if the fi replace
door is opened or if the fl ue is blocked.
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 boiler. If this is too high,
it triggers the shutdown process by disconnecting the electrical
supply to the gear motor.
If the thermostat has tripped, it must be reset by pressing the
red emergency button on the front of the boiler (by opening
right door A - Fig. 1), after removing the protective cap.
The reset button is supplied on the front, inside the boiler
(remove the galvanized sheet-metal panel). For use it must be
removed and repositioned in the seat provided directly above
the initial position (A1 - Fig. 1).
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.
Resistance
It sets off of the combustion of the pellets and it remains lit until
the fl ame has been ignited. This component is subject to wear
Smoke extractor
"Pushes" the smoke into the fl 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.
N.B.:
IF THE BOILER BLOCKS, THE REASON WILL APPEAR ON THE DISPLAY AND THIS WILL BE SAVED.
GENERAL INFORMATION
Tank safety thermostat:
Located on the system that loads the pellets from the hopper.
Trips when the temperature inside the boiler-fi replac is too high.
It stops pellet loading, causing the boiler-fi replace to go out.
Pump (electronic circulator see page 71)
"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.
The subject issuing the declaration of conformity must con-
sider whether an extra tank is necessary, according to the
total volume of water contained in the system!
Gear motor
Activates the screw allowing the transport of the pellets from
the hopper to the burner.
Manometer
Shows the pressure of the water in the boiler.
The recommended pressure is 1.5 bar when the boiler is on.
The pressure meter (B - Fig. 1) is supplied on the front, inside
the boiler (remove the galvanized sheet-metal panel). For use it
must be removed and repositioned in the seat provided directly
above the initial position. (B1 - Fig. 1).
Drain tap
Positioned on the rear of the boiler, this should be opened when
the water inside the boiler must be emptied.
Manual bleed valve
Positioned under the rear panel in positions V1-V2 (see page
65).
This allows bleeding of any air present after the boiler has been
fi lled with water.
