Changing and/or servicing the flame sensor
▀
Disconnect the power supply to the
boiler. Loosen the three wing nuts and
lift the cover up. Note how the flame
sensors wires are colored and remove the cable
tie from the mounting bracket. Disconnect the
terminal block of the flame sensor (1) by pulling
it straight back. Then loosen the burner from
the outer tube by loosening the four wing nuts
(2) Then loosen the nut that holds the flame
sensor in place inside the house. Then take
the flame sensor out and replace with the new.
Reassemble in reverse order. When cleaning
the flame sensor, use a damp cloth after you
loosened the burner from the burner tube.
It is important that the cables are connected the same way to burner as they were, oth-
erwise it will display 100% light all the time and the burner will be faulty.

Overheated fall shaft
On the fall shaft of the pellet burner there is a heat protec-
tion. This activates to protect against backfires. If the pro-
tection tripped, the power is lost to the auger. The cause of
overheating is usually due to large back pressure in the boiler,
which in turn usually depends on:
- Inner combustion tube is full of soot.
- The boiler is full of soot.
- The chimney is too narrow.
- The burner is set too high a power.
Reset the protection by loosen the cover wich is placed in
front of the overheating protection (1). Then press the reset
button (2) and you will hear a click when it is restored.
If the protection is activated again, we recommend that you
contact your installer to review the function and settings.
