8 SAFETY AND ALARMS
CAUTION: During operation, some parts of the boiler (door, handle, ceramic parts) may
reach very high temperatures, therefore be extremely careful, use caution , and always follow
the instructions.
If during operations any part of the boiler or the exhaust pipe leaks smoke, immediately turn off
the boiler without removing the power supply and ventilate the room. Then, once cooled down,
check the reason for the leak and, if necessary, call the specialised technical personnel.
The boiler is equipped with several devices which intervene in order to ensure safe operation.
CAUTION : Safety devices are designed to eliminate any risk of damage to persons,
animals or things, and tampering with them or having unauthorised personnel operate
may compromise their safety.
Safety devices on the boiler are the following:
8.1.1 Fume exhaust pressure sensor
This sensor is connected to the fume exhaust pressure duct. It controls the negative pressure
inside the boiler, monitoring any clogging of the chimney flue, the opening of the combustion
chamber door, and the block of the pellet duct allowing a safe use of the boiler.
When it activates
As already said, the causes that may trigger this alarm are multiple. Below the main ones:
•
If, in the fumes exhaust duct the conditions of correct operation are changed (improper
installation, the presence of obstacles or impediments in the exhaust tube, negligent
maintenance, adverse weather conditions such as persistent wind, etc.).
•
If the boiler flue gas pass contains an accumulation of ash that obstructs the normal passage of
the combustion fumes (poor or negligent maintenance, low quality pellet, improper combustion,
etc.).
•
If the boiler has combustion parameters not adjusted correctly (in particular, the low power
combustion parameters).
•
If the combustion chamber door is left open.
•
If pellet accumulates inside the brazier supply duct (result of incorrect combustion).
In each of the cases above, the vacuum pressure sensor (vacuum thermostat) stops electrical
power supply to the pellet feed screw, thus blocking pellet feeding to the brazier and sending an
alarm signal to the board.
When the alarm is triggered, the display shows the message " AL 8 – NO VACUUM ”.
8.1.2 Boiler /structure temperature sensor
The Termoboiler line boilers are equipped with a manual reset bulb thermostat, which prevents the
boiler water temperature from exceeding 85°C. It is also equipped with a safety thermostat (klixon)
which prevents the structure from reaching excessive temperatures.
When it activates
The bulb thermostat is triggered if the temperature of the water in the boiler exceeds the 85°C
threshold while the klixon triggers if the temperature in the pellet duct exceeds the same 85°C
threshold. In both situations the thermostat interrupts the electrical power supply to the screw
feeder, thereby blocking the pellet supply to the brazier and sending an alarm signal to the board.
The display will show the message
“ AL 7 – Thermal safety ”.
