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 sufcient 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 sufcient draught.
The outlet from the chimney should be above the roof of the buil-
ding 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 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 diameter
of 150 mm and its dimension should be not less than the size of the
outlet socket of the stove.
Any bend in the chimney or connecting uepipe should not exceed
45°. 90° bends should not be used.
Combustible material should not be located where the heat dissipating
through the walls of replaces or ues could ignite it. Therefore
when installing the stove in the presence of combustible materials
due account must be taken of the guidance on the separation of
combustible material given in Building Regulations Approved
Document J and also in these stove instructions.
