Changing and/or servicing the flame detector
▀
Disconnect the power supply to the boiler.
Loosen the three wing nuts and lift the cover
up. Note how the flame sensors are coated
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 feeder tube
On the feeder tube of the pellet burner there is a heat protec-
tion. This turns out to protect against backfires. If the protec-
tion tripped, the voltage disappear to the auger. The cause of
overheating is usually due to large back pressure in the boiler,
which in turn usually depends on:
- Burner tube is full of soot.
- The boiler is full of soot.
- The chimney is too narrow.
- The burner is set to high power.
Reset the protection by loosen the bracket 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.
