Re-connect the cooker oil feed pipe to carbon leg elbow
and tighten.

The cooker burner is now ready for re-lighting.

To Clean the Boiler Burner - See Fig. 20

(i) Remove the top burner baffle 

A

and brush clean both

surfaces free of soot, etc.
(ii) Lift and remove front and back interstage end sealing
plates

of the now exposed top

interstage burner baffle 

E

tilt it slightly and lift out clear of

burner.

Brush clean both surfaces free of soot.
(iv)Holding the finger grip 

F

baffle 

G

tilt it and lift out clear of burner.

Brush clean both surfaces free of soot.
(v) Temporarily plug the main and pilot oil inlet hole in the
burner base bottom and brush/scrape the internal faces of
oil burner and then tip the debris out of the burner.
Withdraw glo-coil igniter 

J

, brush and lightly clean.

Examine coil for deterioration by heat oxidisation, and if in
doubt, replace igniter.
(vi)Remove plug from oil inlet holes, then clean each end
section of the oil feed pipes 

K

and 

O

with a pipe cleaner,

tipping the debris via the inlet end. (Ensure hole is clear).
(vii) With the glo-coil igniter surface clean, check and
ensure that the ignition wick is touching the oil burner
base at the front. Replace if worn. Wick must not touch
glo-coil, 

THIS IS IMPORTANT

.

(vii) Replace all interstage baffles and other baffle plates,
etc, in reverse order of dis-assembly.
(ix)Lift the complete oil burner assembly into the boiler
chamber and push inwards on the reverse manner of
withdrawal.
Before replacing the fire bricks, check that the boiler
burner is level.
Reconnect the oil feed pipe and electrically reconnect the
flame sensor and ignition glo-coil igniter in reverse order
of dis-assembly. Replace boiler strap and secure tightly
with retaining bolts.
The boiler burner is now ready for re-lighting.
NOTE: ENSURE BOTH PILOT AND MAIN FEED PIPES
RISE CONTINUALLY FROM THE LOWEST POINT TO
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
aperture in top plate.
Replace if frayed or damaged.
(viii) Remove layer of paper in combustion chamber base
