Stanley Lismore Installation And Operating Instructions Manual page 6

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 200mm
diameter. 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
Fig.7
Regulations Approved Document J and also in these
stove instructions. See Figs, 9,10,11,12,13 &14 .
