3. APPLIANCE DATA

This product uses a burner gasket containing Refractory Ceramic Fibres (RCF). If the
burner surface is not made of wire mesh then this will also be made of 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 not to touch or disturb the burner surface 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. Do NOT vacuum the burner surface. When
replacing the the burner surface 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 the use of suitable gloves to prevent irritation. We also
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.
This appliance does not contain any component manufactured from asbestos or asbestos
related products.

* When converted using conversion kit number 0575621.
The appliance data label is located on a plate at the base of the fire. This can be seen by
lowering the bottom front cover of the fascia.
