AVOID AIR LOCKING PROBLEMS.
To Clean the Boiler Heat Exchanger and Cooker
Flueways - See Figs 22 and 23
(i) Remove the cooker and boiler burners.
(ii) Place a layer of paper on the boiler and cooker
combustion chamber base area to collect debris when
brushing commences.
(iii)Use the rake and brush to ensure that the flueway
above the oven top is clear and any deposit is removed -
See Fig. 22.
(iv)Lift top plate enamelled cover panel (behind the L.H.
insulating cover) and remove. Remove sealing plate - See
Fig. 23.
Insert flexible rake through top plate aperture, directing it
towards the flue chamber. Clean the boiler outlet flueway,
by scraping the deposits towards the boiler heat
exchanger and vigorously brush if necessary.
Additional access can be obtained via the front of the flue
chamber by removal of the flue chamber door, unscrewing
the four screws securing the flue stabiliser to sealing
plate.
(v) Thoroughly brush boiler heat exchanger cross firebrick
ducts and cooker flueways from the top and bottom of the
heat exchanger until free of debris - See Fig. 22
(vi)Brush and clean in between hotplate ribs on
underside. Examine soft rope seal located on underside
of hotplate baffle plate and replace if worn or frayed.
(vii) Examine soft rope seal located around hotplate
