Wet Stove Installation Guide
• Factory Made Insulated Chimney : Complying with BS 4543:Part 2
(often called Class 1 prefabricated metal chimney). These types of
chimneys should be installed in accordance with Building Regulations
and BS EN 15287-1:2007.
Due to the gradual introduction of European Chimney Standards
chimneys will be specified according to their performance designation as
defined in BS EN 1443 that covers the General Requirements for chimneys.
The minimum performance designation required for use with solid fuel
burning stoves is T600 N2 S D3.
The flue and chimney installation must be carefully checked by a
competent person before fitting the stove to ensure it is suitable and will
work safely.
If the chimney is old (i.e: built of brick or stone without a liner) or being
opened up for reuse additional checks and smoke testing as described in
Appendix E of the Approved Document J 2010 Edition should also be carried
out to ensure the flue and chimney are in good operating condition.
Check the existing flue is in good condition with suitable access for
collection and removal of debris.
It is also important that suitable flue pipe (recommended at least
600mm in length) complying with the Building Regulations is used to
connect the stove to the flue in the chimney. Suitable access should be
provided into the flue for regular inspection and sweeping of the flue ways.
The installer should comply with Building Regulations requirements in
respect of providing a Notice Plate giving details on the chimney, flue lining,
hearth and fireplace installation.
Chimneys should be as straight as possible. Horizontal runs should be
avoided except where the rear outlet of the appliance is used, in which case
the horizontal section should not exceed 150mm in length. If necessary
a combination of
45
◦
and
90
◦
bends can be used as long as the sum of
their angles is not greater then
180
◦
in total. i.e four
45
◦
bends, or two
45
◦
and a
90
◦
bend.
