Servicing & Parts Replacement; Burner Plaque Replacement - Valor 417 Installation And Servicing 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"
