2. APPLIANCE DATA

The appliance data label is located on a plate at the base of the fire. This can be seen by
removing the lower front casting / fire front.

The efficiency of this appliance has been measured as specified in BS EN 613 and the
result is as below :

Model

Efficiency % (Gross)

541

76

The gross calorific value of the fuel has been used for this efficiency calculation. The
test data from which it has been calculated has been certified by Advantica Certification
services (0087). The efficiency value may be used in the UK Government's Standard
Assessment Procedure (SAP) for energy rating of dwellings.

The conversion of 

net 

efficiency to 

gross

was achieved by multiplying the net

efficiency by the following conversion factor from Table E3 of SAP 2005, rounding
down to the nearest whole number.

This product uses a fuel effect, a burner compartment rear wall and gaskets
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. This appliance does
not contain any component manufactured from asbestos or asbestos related
products.
