9.3 Cleaning the Burner & Injectors
1. Undo the screw holding the burner to the
controls mounting plate, and disengage the
burner inlet from the injector (Fig. 49).

3. Using a spanner on both the adaptor barrel
and fire injector, remove the injector from the
barrel (Fig. 50).

NOTE: No attempt should be made to clean
the device using any hard tools, including
pins or wire.
WARNING: The pilot/A.S.D. assembly must
not be adjusted in any way.
1. The A.S.D. must not be altered so that it will
not operate or be bypassed in any way.
2. Ensure that the pilot burner aeration hole is
free from lint, debris etc.
3. If necessary clean the electrode and target,
and check that the spark gap is 2.5 - 4.0mm.
