Remove the cases (
Part 1
), the E.C.U. (

chamber and discard.
Refitting the Combustion Chamber:
1)
Place a new rubber O-ring (

) into the recess of the combustion
chamber.

Insert the combustion tube (

3)
Replace and tighten the 4 x hex bolts into the top of the combustion
chamber to 4 ± 0.4 Nm to secure it in place.
4)
Replace the burner assembly (
Part 5
), the air motor (
Part 4
), the E.C.U.
(
