Main components and their operation
SMOKE PRESSURE SWITCH
This is a safety switch that stops the screw feeder motor whenever necessary. The main cause for the pressure switch tripping is a blocked
flue outlet or smoke exhaust pipe. Note that it is strictly forbidden to apply any kind of mesh screen to the end of the pipe. When the holes of the
mesh clog up they create a plug that trips the pressure switch which stops the pellet feeder.
SCREW FEEDER MOTOR
This motor is powered at regular on/off intervals controlled by a microprocessor. The operation of this motor is affected when:
-
The motor's thermal cutout trips.
-
The pressure switch trips due to blocked smoke exhaust.
-
Pellets finished.
-
Intentional shut down of the heater / boiler.
-Safety thermostat with manual reset trips.
SMOKE SUCTION UNIT
This is activated when the start up signal is given. In the first two minutes it «washes» the smoke discharge tube, that is, it functions at maximum
working rate. Once this time has elapsed it self-adjusts to the optimal speed. The exhaust continues to operate for approximately one hour from
the time the heater / boiler is switched off to allow for the evacuation of all the smoke and for safety purposes. It stops about half an hour after
the thermostat at 42°C opens.
