either square or round and MUST NOT BE LESS THAN 125 mm
(5") for C-Four and C-Five or 150mm (6") for C-Six, C-Seven and C-
Eight.
If an existing chimney is to be used it must be swept and checked, it
must be in good condition, free from cracks and blockages, and
should not have an excessive cross sectional area. If it was previously
used by an open fire then the chimney should be swept one month
after installation to clear any soot falls which may have occurred due
to the difference in combustion between the stove and the open fire.
If you find that the chimney is in poor condition then expert advice
should be sought regarding the necessity of having the chimney lined.
If it is found necessary to line the chimney then a lining suitable for
Solid Fuel must be used.
If there is no existing chimney then a prefabricated block chimney or
a twin walled insulated stainless steel flue to BSEN 15287-1:2007 can
be used either internally or externally. These chimneys must be fitted
in accordance with the manufacturers instructions and Building
Regulations.
Single wall flue pipe is suitable for connecting the stove to the
chimney but is not suitable for using for the complete chimney. If it is
found that there is excessive draw in the chimney then a draught
stabiliser should be fitted.
It is important that there is sufficient draw in the chimney and that
the chimney does not suffer from down-draught. When the chimney
is warm the draw should be not less than 2.5mm (0.10") water gauge
(25 Pa). If in doubt about the chimney seek expert advice.
HEARTH AND FIRE SURROUND
The stove must stand on a fireproof hearth and must not be situated
closer than the minimum distance from combustible materials (see
specification table) to the sides or rear above hearth level unless
adequately fireproofed in accordance with local building regulations.
The hearth must be of fireproof material and at least 12mm (1/2in.)
thick. The positioning of the stove and the size of the hearth are
governed by building regulations for Class 1 appliances. These
building regulations state that the hearth must extend in front of the
stove by at least 300mm (12 in.) and to the sides of the stove by at
least 150mm (6 in.).
If in doubt as to the positioning of the stove, expert advice should be
When the fire door is open, it extends beyond
the flat front of the stove by the following amounts:
C-Four & C-Six 365mm, C-Five 436mm, C-Seven 515mm, and C-
Eight 450mm.
