IMPORTANT.
These appliances are certificated by the British
Standards Institution 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 BSI 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 this 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.
