PREPARATORY WORK AND SAFETY CHECKS
IMPORTANT WARNING
This stove must not be installed into a chimney that serves any
other heating appliance.
There must not be an extractor fan tted in the same room as the
stove as this can cause the stove to emit fumes into the room.
Chimney
In order for the stove to perform satisfactorily the chimney height
must be sufcient to ensure an adequate draught of approximately
15 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 ver-
tically 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 sufcient draught.
The outlet from the chimney should be above the roof of the buil-
ding in accordance with the provisions of Building Regulations Ap-
proved 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 ue
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 tted in place of an open re 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 re.
If there is no existing chimney then any new system must be to the
designation described above and in accordance with Building Regu-
lations Approved Document J.
A single wall metal uepipe is suitable for connecting the stove to
the chimney but is not suitable for use as the complete chimney.
The chimney and connecting uepipe must have a minimum diame-
ter of 150 mm and its dimension should be not less than the size of
