Safety components
Drop tube
Between the storage and the feeder there is a meltable plastic tube which is
destroyed when it is overheated.
The overheat protection on the fall shaft
This stops the feeding and the fire damper if the fan temperatures gets
too high. Reset is made manually.The cover must always be in place when
connected to main power. It only cuts the power to the auger and fire damper.
Safety lock
If the boiler is equiped with a suction system there is a fire damper mounted.
This is closed during filling, overheating or loss of power.
Flame sensor
The flame sensor monitors the flame in the burner. If a valid value is lost for
more than 120sec the feeder stops. The burner is cooled down with maximum
rpm of the fan for (X) minutes before stopping. The pellets suction is not
allowed to start if the flame sensor detects light
Overheat protection on the boiler
There is overheat protection on the boiler which cuts the power to both the
boiler and the burner if the temperature in the boiler exceeds 95°C.
Compressed air cleaning
On the cleaning to the burner there are two safety systems. The controller
limits the the time the compressor is allowed to run, there is also a pressure
switch which closes the compressor when preinstalled pressure is reached.
Flue gas fan
A flue gas fan is mounted on the flue tube. The fan helps to maintain a stable
underpressure in the boiler and prevents back heat but also improves the com-
bustion. More on the fans adjustements are on pg. 33.
Door switch
The door switch stops the auger/feeder and no more pellets are fed into the
burner when the door to the combustion chamber is open.
Automatic fuses
Automatic fuses are installed in the electrical system, which are triggered if
there are any eletrical faults in the boiler. If triggered, an authorized electrician
should be contacted to determine the cause.
