Servicing; Burner Plaque Removal; Burner Unit Removal; Pilot Unit Removal - Valor COSYFLAME BR623 Installer's Manual

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.
TO REPLACE BURNER PLAQUES
• Remove the 9 loose coals, front base coal, and rear base coal.
• Remove the plaque clamping strips by detaching 6 screws.
• Remove the plaques and the combination gasket between and under the plaques. If necessary remove the gauze and the
gasket beneath it.
• 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.
• 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.
• 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.
• 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.
• Refit the ceramic fuel effects and walls as described in this manual.
•
TO REMOVE THE COMPLETE BURNER UNIT
• Remove the 9 loose coals, front base coal and rear base coal.
• Support the inlet isolating elbow to avoid straining the pipework and disconnect the appliance from the elbow.
• Detach the burner unit from the hotbox by removing 1 screw (As shown in figure 5).
• Replace in the reverse order.
TO REMOVE THE PILOT UNIT
• Remove the burner unit - See previous section.
• Disconnect the electrode lead from tab underneath the electrode.
• Undo the thermocouple nut at the gas tap.
• Disconnect the pilot pipe from the pilot unit elbow.
• Remove the first screw securing the dust cage to the pilot unit / burner. Carefully remove the dust cage and place aside.
• Remove the second screw securing the pilot unit to the burner. Remove the pilot unit and place it aside
• Refit in the reverse order
Note 1 The pilot unit must be replaced as a whole assembly. Its individual components are not separately replaceable.
2. Once removed, ensure that the dust cage is cleaned before refitting. Make sure that it locates squarely onto the pilot unit without
any gaps between the cage edges and the pilot unit.
