Replacing igniter
4.8.1
For replacing the igniter a small (2,5 ... 3,5 mm) flat screwdriver in order to connect the wires and a
cross-head screwdriver for replacing the igniter are needed.
1.
Be sure that burner has cooled down and disconnected from power circuit.
2.
Remove burner’s red cover by loosening 4 screws (2 on both sides). See Figure 7.
3.
Disconnect igniter’s wires from screw connector X1.
4.
Turn loose the screw that attaches the igniter to its case.
5.
Open boilers door to get access to the burning chamber.
6.
Press igniter into burning chamber and take it out through the burning chamber.
7.
Swirl the wires of the new igniter together and put them through the burning chamber into the
socket of igniter.
8.
Push the igniter so deep into its case that the igniter’s end would be on the same level with burning
chamber’s rear wall.
Caution!
If igniter is out of its opening, then it will get to contact directly with pellets and flame. In
that case iginiter burns out very quickly.
9.
Tighten the fixing screw again and make sure that the igniter’s other end would not be in touch with
the rear wall of the burning chamber.
10.
Reconnect the wires back to connector X1 terminals 1 and 2.. The order is not important. Screw
terminal must be tightened so hard that when pulling the wires, they would not come out from
under the screw.
