There must not be an extractor fan fitted in the same room as the stove as this can cause the stove to emit
fumes into the room.
Chimney
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 BS 5854:1980
may be used as the basis for deciding whether a particular chimney design will provide sufficient
draught.
If installation is into an existing chimney then it must be sound and free from cracks or other faults which
might allow fumes into the property.
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 either a prefabricated block chimney in accordance with Building
Regulations Approved Document J or a twin walled insulated stainless steel flue to BS 4543 can be used.
These chimneys must be fitted in accordance with the manufacturer’s instructions and Building
Regulations.
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not suitable for
using for the complete chimney. The chimney must have a minimum diameter of 150 mm and its
dimension should be not less than the size of the outlet spigot of the stove.
Any bend in the chimney or connecting fluepipe should not exceed 45°. 90° bends are not permitted.
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 the stove installation instructions.
If it is found that there is excessive draught in the chimney then a draught stabiliser should be fitted.
All joints in the connection between the stove and the chimney must be made gastight using the rope gasket
provided and if required a suitable sealant.
The chimney can be swept through the stove if the stove is connected via the top flue outlet. When
installing via the rear flue outlet adequate provision e.g. easily accessible soot door or doors must be
provided for sweeping the chimney and connecting fluepipe. It may also be necessary to provide
additional sweeping access when fluing through a register plate.
Hearth
The hearth should be able to accommodate the weight of the stove and its chimney if the chimney is
not independently supported. The weight of the stove is indicated in the brochure.
The stove should always be installed on a non-combustible hearth of a size and construction that is in
accordance with the provisions of the current Building Regulations Approved Document J.
The clearance distances to combustible material beneath, surrounding or upon the hearth and walls
adjacent to the hearth should comply with the guidance on the separation of combustible material
given in Building Regulations Approved Document J and also in the stove instructions.
If the stove is to be installed on a wooden floor, it must be covered with a non-combustible material at
least 12mm thick, in accordance with Building Regulations Approved Document J, to a distance of 30
