Safety system against back burning
The pellet burner is equipped with two safety systems for
protection against back burning and a flame retardant
hose of ”self-extinguishing” quality.
DROP SHAFT cuts the pellet supply from the supply screw.
The drop shaft on the burner is 250 mm. The screw is con-
nected to the burner via a flame retardant, self-extinguish-
ing hose. As the burner does not have an internal store
area, there are only enough pellets in the burner to be
burned on the grate.
HEATING CORE on the connection pipe. If the overheating
protection on the connection pipe senses heat (>90 °C),
the supplier screw stops. If the overheating protection
deploys, it must be reset. This is carried out by first cutting
the main power and then unscrewing the cover on the
connection pipe as well as pressing in the small ”reset tab”
(1) on the overheating protection. Before resetting, the
cover must be screwed back into place.
The burner is also equipped with a switch on the door
frame, the switch prevents the burner from starting when
it is pulled out from the boiler for cleaning. A monitoring
function for the fan and supply screw is integrated in the
circuit board.
