CHIMNEY
Do not connect to a chimney serving another
appliance.
The stove is a radiant room heater and must be con-
nected to a chimney of the proper size and type.
The chimney must have a cross-sectional area of at
least 30 square inches 19350sq. mm or a diameter
of at least 6" (150mm). It is best to connect to a
chimney of the same size, as connection to a larger
size may result in a somewhat less draught. Do not
connect to a chimney serving another appliance.
In adverse weather conditions, down drafts may be
experienced causing smoke or fumes to spill into the
room. If this occurs shut the appliance down by
closing the air controls. If the problem persists seek
the advice of a chimney sweep.
In order for the stove to perform satisfactorily the
chimney height must be sufficient to ensure an ade-
quate draught of approximately 12 Pa so as to clear
the products of combustion and prevent smoke
problems into the room.
NOTE: A chimney height of not less than 4.5 metres
measured vertically from the outlet of the stove to
the top of the chimney should be satisfactory.
Alternatively the calculation procedure given in EN
13384-1 may be used as the basis for deciding
whether a particular chimney design will provide suf-
ficient draught.
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 it must
be sound and have no cracks or other faults which
might allow fumes into the house. Older properties,
especially, may have chimney faults or the cross
section may be too large i.e. more than 230 mm x
230 mm. Remedial action should be taken, if
required, seeking expert advice, if necessary. If it is
found necessary to line the chimney then a flue liner
suitable for solid fuel must be used in accordance
with Building Regulations Approved Document J.
Any existing chimney must be clear of obstruction
and have been swept clean immediately before
installation of the stove. If the stove is fitted in place
of 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 there is no existing chimney then any new system
must be to the designation described above and in
accordance with Building Regulations Approved
Document J.
A single wall metal fluepipe is suitable for connecting
the stove to the chimney but is not suitable for use
as the complete chimney. The chimney and con-
necting flue must have a minimum diameter of
150mm and at no point must the diameter reduce to
less than the size of the outlet socket of the stove.
Any bend in the chimney or connecting fluepipe
should not exceed 45
used.
Combustible material should not be located where
the heat dissipating through the walls of fireplaces or
flues could ignite it. Therefore when installing the
stove in the presence of combustible materials due
account must be taken of the guidance on the sepa-
ration of combustible material given in Building
Regulations Approved Document J and also in these
stove instructions.
If it is found that there is excessive draught in the
chimney then a draught stabiliser should be fitted.
Fitting of a draught stabiliser will affect the require-
ment for the permanent air supply into the room in
which the stove is fitted in accordance with
Approved Document J (see also combustion air sup-
ply).
Adequate provision e.g. easily accessible soot door
or doors must be provided for sweeping the chimney
and connecting fluepipe.
