INSTALLATION
Ways of meeting the requirements when proposing factory-made
metal chimneys include:
•
Using component systems appropriately designated in
accordance with BS EN 1856-1:2003 to suit the appliance
and installing them in accordance with the relevant
recommendations of BS EN 15287-1:2007
Where a factory-made metal chimney passes through a wall,
sleeves should be provided to prevent damage to the flue or
building through thermal expansion. To facilitate the checking of
gas tightness, joints between chimney sections should not be
concealed within ceiling joist spaces or within the thickness of walls
without proper access being provided.

USE OF FLEXIBLE METAL FLUE LINERS FOR THE RELINING OF CHIMNEY
A way of relining an existing chimney would be to use a flexible
metal flue liner, appropriately designated in accordance with BS EN
1856-2:2004 to suit the appliance, fuel and flue gas characteristics.

When providing a factory-made metal chimney, provision should
be made to withdraw the appliance without the need to dismantle
the chimney.
Factory-made metal chimneys should be kept a suitable distance
away from combustible materials. Ways of meeting the requirements
for chimneys designated to BS EN 1856-1:2003 comprise:
•
Locating the chimney not less than distance 'xx' from
combustible material, where 'xx' is defined in BS EN 1856-
1:2003 as shown in the diagram below.
•
Where a chimney passes through a cupboard, storage space
or roof space, providing a guard placed no closer to the outer
wall of the chimney than the distance noted above.
No combustible material in
shaded zone. Width of
shaded zone at least equal to
manufacturer's declared
minimum distance (xxmm) as
designated to BS EN 1856-1
Flexible flue liners should only be used to reline an existing chimney
and should not be used as the primary liner of a new chimney.
