Planning
Please ensure that you are familiar with the installation
requirements as well as the relevant British Standards
and Statutory Regulations (see page 2) before
commencing work.
Location
The DUO 55 can be installed on any suitable internal
wall. Provision must be made to allow the correct routing
of the flue and siting of the terminal to allow the safe
and efficient removal of the flue products. The appliance
may be installed in any room, although reference must
be made to the IEE regulations if it contains a bath or
shower. A compartment or cupboard may be used
provided that it has been purpose-built or modified for
the purpose. It is not necessary to provided permanent
ventilation for cooling purposes.
Detailed
recommendations are given in BS 5440 pt. 2. If it is
proposed that it is installed in a timber framed building
then reference must be made to British Gas Document
DM2, or advice sought from CORGI.

Installation must be carried out by a suitably qualified
installer and in accordance with current regulations

The boiler, cylinder and ancillary controls must be
adequately maintained.
The installation must have a sufficient and constant

No valve should be fitted between the expansion relief
