Fig. 98
1. The heat exchanger may be cleaned by
insertion of a thin metal strip e.g. a hack saw
blade or steel rule, from above or below, taking
care not to damage any insulation.
2. Clean the front and rear fin sections and
ensure that any blockages are cleared.
10.4 Cleaning the Burner Injector

burner feed manifold (Fig. 99).
2. Examine and clean carefully, then replace
ensuring that the copper washer is in position.
Tighten the injector fully.

electrode (Fig. 100).
2. Unscrew the electrode from the manifold and
withdraw the electrode (Fig. 100).

bracket by releasing the screw. Remove the side
insulation (Fig. 101).

replace if it is damaged in any way. Reassemble
in reverse order.
7. Replace all components in reverse order
ensuring that the flexible tubes from the fan
unit to the pressure switch are routed
correctly and that they are not kinked or
flattened (Fig. 95).
8. Check that the seal to the combustion box door
is good.
9. Re-commission the boiler before use, checking
for gas soundness and ensuring all controls are
working correctly.
