Chimney and Flue Requirements
The liner diameter must not be less than 6 inch (150mm) and no more than 9 by 9 inch (225mm by
225mm) square. It is most important that there is no obstruction in the flue. Sweep clean immediately
before installation of the stove. If the chimney has previously been used for an open fire it is
recommended that it be swept for a second time after the stove has been used for a month. As a closed
appliance operates at a higher flue temperature, it is possible for deposits which previously adhered to
now be dislodged, with the consequent risk of soot falls and flue blockage.
A flue draught of minimum 12Pa (0.05ins wg) to a maximum 16 Pa (0.065ins wg) is required for
satisfactory appliance performance. A properly built masonry or factory constructed chimney, preferably
with a height of 5 metres or more, should ensure a consistent draught (draw) under a variety of weather
conditions. The flue draught should be checked ‘under ‐ fire’ at high output and if it exceeds the
recommended maximum, a draught stabiliser should be fitted to prevent over firing (see 5 below). This
appliance must not be connected to a flue serving another heating appliance. The outlet from the
chimney should be above the roof of the building in accordance with the provisions of Building
Regulations Approved Document J.
If installation is into an existing chimney then the chimney must be sound and have no cracks or other
faults which might allow fumes into the house. If there is any uncertainty, seek expert advice as
remedial action should be taken. If it is found necessary to line the chimney then a flue liner suitable for
manufactured or naturally occurring smokeless fuels and wood logs must be installed in accordance with
Building Regulations Approved Document J.
If there is no existing chimney then either a prefabricated block chimney in accordance with Building
Regulations Approved Document J or a twin walled insulated stainless steel flue to BS 4543 can be used.
These chimneys must be fitted in accordance with the manufacturer’s instructions and Building
Regulations.
The liner diameter must not be less than 6”. If the draw on the chimney is excessive, a flue draught
stabiliser will help to slow this down. An excessive draw may cause over firing and thus cause the
internal components of the stove to wear out quicker.
Any bend in the chimney or connecting fluepipe should not exceed 45
°
. 90
°
bends should not be used.
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimney
and connecting fluepipe.
With reference to the above All relevant flue or chimney installations must adhere to BS EN 15287 ‐
1:2007 Design, installation and commissioning of chimneys.
