Servicing & Parts Replacement; Checking The Aeration Setting Of The Burner - Baxi 741 Installer's Manual

17. SERVICING & PARTS REPLACEMENT
Always turn off the gas supply 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 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. 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 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 and ceramic fuel effect pieces are
!
replaced correctly as described in the installation instructions.
Always test for gas soundness and spillage after
!
servicing the appliance.
