Installation Instructions
Chimney and Connector
Connection to chimney
Tis stove has a top flue gas connector that allows connection to either a masonry chimney or a prefabricated factory
made insulated metal chimney in accordance with their instructions. In some cases it may be necessary to fit an adaptor
to increase the diameter of the flue to the minimum required 150 mm section of the chimney or liner. All joints in the
connection between the stove and the chimney must be made gastight using fire cement and where necessary fire-proof
rope infill. Means should be made for sweeping the entire length of the flue, be that through the appliance or by suitable
sweeping hatch in the flue.
• installed with the crimped or male ends pointing down. This will carry any liquid creosote or condensation back into
the stove.
• Installed according to the chimney/chimney pipe manufacturer's installation and safety guidelines
Chimney
In order for the stove to perform satisfactorily the chimney height must be sufficient 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 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 sufficient draught. BS EN 15287-1:2007 gives additional
details.
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 connecting fluepipe 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 fluepipe should not exceed 45 degrees. 90 degree bends should not be 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 separation 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 requirement for the permanent air supply into the room in which the stove is fitted in accordance
with Approved Document J (see also combustion air supply).
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimney and
connecting fluepipe where it is not intended for the chimney to be swept through the appliance.
