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.
An existing masonry chimney should be inspected
and if necessary repaired by a competent mason.
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, poor draught conditions will
result in poor performance.
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.
