External auger
A feeding auger transports pellets from the pellet container to the burner. The burner controls the work
of the auger. The auger is connected to the burner with a special hose. The hose is made of melting
material that acts as a safety measure against back-burning. The upper side of auger (with motor) must
be fixed to the storage or to some other object nearby (with delivered chain).
Figure 12 shows correct position for external auger. As the hose is a safety device, it must be placed
strictly as described below. The vertical distance between auger outlet and burner inlet must be in range
of 40 to 70 cm and horizontal displacement 10 to 20 cm (typical auger angle 30
o
..45
o
). External auger
cannot be installed in position with angle greater than 45
o
. The hose must be in angle of 50
o
or more to
ensure free falling of the fuel.
Auger cable must be connected to the left of the burner. Make sure the connector is fully inserted into
socket.
