Servicing & Parts Replacement; Checking The Aeration Setting Of The Burner - Valor 961 Installation And Owner's Manual

17. SERVICING & PARTS REPLACEMENT
Always turn off the gas supply before commencing any servicing and allow
to cool completely. (The appliance inlet 'T' connector incorporates an isolating
valve).
It is recommended that, at least once a year, the appliance is disconnected
and the fireplace opening checked and cleared of any debris.
This product uses fuel effect pieces and burner compartment walls
containing Refractory Ceramic Fibres (RCF), which are man-made vitreous
silicate fibres. Excessive exposure to these materials may cause irritation to
eyes, skin and respiratory tract. Consequently, it is important 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. RCF waste is classed
as a stable, non-reactive hazardous waste and may be disposed at a landfill
licensed to accept such 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 ceramic fuel effect pieces 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 are replaced and the ceramic
fuel effect pieces are replaced correctly as described in the installer and owner guide
supplied with the ceramic fuel effect. The ceramic fuel effect guide may have been
placed inside or attached to this guide.
Always test for gas soundness and spillage after servicing the appliance.
