IMPORTANT.

 These appliances are certificated by the BG

Technology Certification Services for safety and performance. It
is, therefore, important that no external control devices, e.g. flue
dampers, economisers etc., are directly connected to these
appliances -unless covered by these Installation and Servicing
instructions or otherwise recommended by 

Caradon Plumbing

Limited

 in writing. If in doubt please enquire.

Any direct reconnection of a control device not approved by

Caradon Plumbing Limited

 could invalidate the certification and

the normal appliance warranty. It could also infringe the Gas
Safety Regulations and the above regulations.

SAFE HANDLING OF SUBSTANCES

Care should be taken when handling the boiler insulation panels,
which can cause irritation to the skin.  No asbestos, mercury or
CFCs are included in any part of the boiler.

LOCATION OF BOILER

The boiler must be installed on a flat and vertical  wall, capable of
adequately supporting the weight of the boiler and any ancillary
equipment.

The boiler may be fitted on a combustible wall and insulation
between the wall and the boiler is not necessary - unless required
by the local authority. 

The boiler must not be fitted outside.

Timber Framed Buildings

If the boiler is to be fitted in a timber framed building it should be
fitted in accordance with the  Institute of Gas Engineering
document IGE/UP/7:1998.

Bathrooms

The boiler may be installed in any room or internal space,
although particular attention is drawn to the requirements of the
current I.E.E. (BS.7671) Wiring Regulations and, in Scotland, the
electrical provisions of the building regulations applicable in
Scotland with respect to the installation of the boiler in a room or
internal space containing a bath or shower.
