• 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 (SF o AL 07).
Flow sensor
Positioned in the aspiration channel, the sensor stops the boiler
when the fl ow of comburent air is incorrect (and which could
cause the consequent risk of problems of depression 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.
If the thermostat has been tripped it must be reset using the re-
set button behind the boiler after having removed the protective
cap (A - fi g. 1).
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.
Minimum-pressure pressure switch (water):
Situated on the hydraulic circuit, it cuts in to block the boiler
when the system pressure is low.
Check there are no leaks and re-establish the correct system
pressure by adding water from the dedicated circuit
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.
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
Activate the feed screw, which allows the pellets to be transfer-
red from the hopper to the combustion chamber.
Manometer
positioned on the inner front of the boiler (opening cover B -
fi g. 2), and shows the pressure of the water in the boiler.
The recommended pressure is 1.5 bar when the boiler is on.
Manual bleed valve
Positioned on the inner front of the boiler (opening the door
- page 37), This allows bleeding of any air present after the
boiler has been fi lled with water.
