Servicing & Parts Replacement - Baxi 748 Installer's Manual

16. SERVICING & PARTS REPLACEMENT
Always turn off the gas supply and allow the appliance to cool completely before
commencing any servicing (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 a burner compartment rear wall
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 holes in the main burner.
!
After servicing, make sure that 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 should be placed inside or attached to this guide.
Always test for gas soundness and spillage after servicing the appliance.
