Chimney
For correct operation of the stove, the height of the
chimney from its base should not be less than 4.5m and
it should terminate above the roof in accordance with
current Building Regulations. All requirements as
outlined in BS 6461 Part 1 and BS 7566 Parts 1 to 4
should be observed.
Failure to observe the
recommended minimum sizes or methods of flue
connection may lead to fume emission and reduce
burning rates.
When fitting the stove to an existing chimney, its internal
and external condition should be checked before the
appliance is installed. The chimney must be swept
before installation. The flue must be stable and free
from all jointing compounds.
Ensure a new chimney is free of internal projections,
such as jointing compounds, before installing the
appliance. The stove must not share a chimney with
another appliance.
When using a factory-made insulated chimney, it must
comply with BS 4543 Parts 1 and 2. The recommended
diameter is 150mm; contact the chimney manufacturer
for further advice.
After deciding whether to use the top or rear exit on the
stove, fit the flue socket plate and blanking plates in the
required positions, ensuring a good seal is made with
fire cement or similar. When using the rear exit, always
use an appropriate tee; a 90° elbow should not be used.
Advise the end user to have the chimney thoroughly
swept at least every twelve months. If bituminous coal
or wood is used, the chimney may require more
frequent sweeping.
Flue layout
If the stove is installed in an existing recess directly
below a chimney flue, the exhaust end of the flue pipe
must extend into the throat of the chimney, at least
150mm into the overhanging brickwork. Any cavities or
pockets above the throat plate should be filled.
If the stove is connected via flue pipe to an existing
brick chimney, square bends and horizontal runs must
not be used. A cleaning door must be included at every
bend. See
fig 4
below for details.
Avoid extended horizontal flue runs. Whichever method
of installation is used, air must not be allowed to enter
the chimney, save through the stove; all joints must be
airtight. If the chimney is unlined and there is doubt as
to its condition, it should be lined in accordance with
current Building Regulations.
Provision must always be made for sweeping the
chimney. Cement pipes and fittings must not be used
within 2m of the stove outlet. Plain pipe chimneys are
not recommended, but propriety makes of insulated
chimneys may be suitable; refer to manufacturers'
guidance.
CO Alarms
Building regulations require that whenever a new or
replacement fixed solid fuel or wood biomass appliance
is installed in a dwelling a carbon monoxide alarm must
be fitted in the same room as the appliance. Further
guidance on the installation of the carbon monoxide
alarm is available in BS EN 50292 :2002 and from the
alarm manufacturer’s instructions
. Provision of an
alarm must not be considered a substitute for
either installing the appliance correctly or ensuring
regular servicing and maintenance of the appliance
and chimney system
