SAFETY AND DETECTION DEVICES
Smoke thermocouple
placed on the smoke exhaust pipe to detect the temperature. It controls the ignition phase and if the temperature is too high or too low
it triggers a block phase (Stop Flame or Overheated Smoke).
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 sensor
measures the temperature of the water inside the boiler-stove and sends the information to the card for the management of the boiler-
stove's power modulation. If the temperature is too high, a block phase is triggered.
Water overheating safety thermostat with manual reset
measures the temperature of the water inside the boiler-stove. If the temperature is too high, it cuts off the motor's electrical power
supply. In the event that the thermostat has been operated, it must be re-activated by acting on the reset button behind the boiler-stove
(see page. 40).
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
located on the rear left side, it allows you to read the water pressure in the boiler-stove. With the boiler-stove running, the recommen-
ded pressure is 1bar (see page. 32).
IF THE BOILER-STOVE BLOCKS, THE REASON WILL APPEAR ON THE DISPLAY AND THIS WILL BE SAVED.
COMPONENTS
Resistance
triggers pellet combustion. It remains on until the smoke temperature increases by 15 °C from that prior to ignition.
Smoke extractor
"pushes" the smoke into the flue and draws out combustion air via a vacuum.
Gear motors
activates the feed screw, which allows the pellets to be transferred 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 inside the boiler-stove due to the heating effect.
A heating technician must evaluate the need to add a second tank to the existing one, depending on total amount of water in the system.
Venting valve:
positioned in the upper part, it allows for the "bleeding" of any air present during the loading of water inside the boiler-stove.
Drain tap
placed inside the lower part of the boiler-stove. This is to be opened if the water inside the boiler-stove must be emptied.
