IMPORTANT INFORMATION
This product contains Refractory Ceramic Fibres (R.C.F.) which
are man-made vitreous silicate fibres. Excessive exposure to
these materials may cause temporary irritation to eyes, skin and
respiratory tract. Care must be taken when handling these
articles to ensure the release of dust or fibres is kept to a
minimum. To ensure that the release of fibres from these
articles is kept to a minimum, during installation and servicing it
is recommended that a H.E.P.A. filtered vacuum is used to
remove any dust, soot or other debris accumulated in and
around the appliance. This should be performed before and
after working on the installation. It is recommended that any
replaced item(s) are not broken up but sealed within heavy duty
polythene bags and clearly labelled "R.C.F. 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 it is recommended that gloves are worn and the normal
hygiene rules of not smoking, eating or drinking in the work area
are followed and always wash hands before eating or drinking.
SITING
The boiler must be fitted on a suitable outside wall, the position
permitting a satisfactory flue location and an adequate air
supply.
A new or existing cupboard or compartment used to enclose the
boiler must be constructed specifically for this purpose.
Details of essential features of cupboard! Compartment
design are given in BS 5440:2.

VENTILATION
Detailed recommendations for air supply are given in
BS 5440:2.
The room in which the boiler is installed does not require a
purpose provided air vent. When the boiler is installed in a
purpose made cupboard, air vents are required (for cooling
purposes) at high and low level. These vents may communicate
with a room or direct to outside air.
The minimum effective area requirements of
cupboard/compartment air vents are as follows:
