10. SERVICING & PARTS REPLACEMENT
•
Always turn off the gas supply before commencing any servicing. (The inlet elbow for this appliance incorporates an isolating valve).
•
This product uses fuel effect pieces, burner compartment walls and gaskets containing Refractory Ceramic Fibres (RCF), which are
man-made vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation to eyes, skin and respiratory
tract. Consequently, it makes sense to take care when handling these articles to ensure that the release of dust is kept to a minimum. To
ensure that the release of fibres from these RCF articles is kept to a minimum, during installation and servicing we recommend that
you use a HEPA filtered vacuum to remove any dust and soot accumulated in and around the fire before and after working on the fire.
When replacing these articles we recommend that the replaced items are not broken up, but are sealed within a heavy duty polythene
bag, clearly labelled as RCF waste. This is not classified as “hazardous waste” and may be disposed of at a tipping site licensed for the
disposal of industrial waste. Protective clothing is not required when handling these articles, but we recommend you follow the normal
hygiene rules of not smoking, eating or drinking in the work area and always wash your hands before eating or drinking.
•
Check that the appliance is clean and that soot or debris is not blocking the gaps between the coals causing an imperfect flame.
•
Check that soot or debris is not impairing the electrode spark or pilot burner.
•
Check that soot or debris is not blocking any of the slots in the main burner.
•
After servicing, make sure that the ceramic walls and coals are replaced correctly as described in the installation instructions.
•
Always test for gas soundness and spillage after servicing the appliance.

10.1To Replace Burner Plaques
(See Figure 20
)
10.1.1
Remove the 15 loose coals, front base coal and rear
base coal.
10.1.2
Remove the plaque clamping strips by detaching 6
screws.
10.1.3
Remove the plaques and the combination gasket
between and under the plaques. If necessary remove the gauze
and the gasket beneath
it.
10.1.4
If necessary
fit a new gasket below
the gauze. Clean and
replace the gauze. Fit a
new combination gasket
below the plaques. Push
the gasket ends inwards
to form a dividing
gasket between the
plaques.
10.1.5
Place the
new left hand plaque in
position. The left side
of the plaque must
touch the inside edge of the retaining flange at the left side of
the burner well.
10.1.6
Place the new right hand plaque in position. Make
sure that the centre section of the combination plaque is
between the two plaques. If there is any play between the
plaques and the end retaining flanges, push the plaques firmly
to the left squeezing the centre section of the combination
gasket between the two plaques. Any gap should be between
the right side of the plaque and the right side retaining flange.
10.1.7
Fit the front and rear plaque clamping strips. Make
sure that the plaques are as far to the left as possible. .
It is
important that the left side plaque is accurately positioned so
that it has the correct relationship to the pilot.
Fully tighten the
clamping strips.
10.1.8
Refit the ceramic fuel effects and walls as described
in section 7 of this manual.
