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 fitted in the same room as the stove as this can cause the stove
to emit fumes into the room.
Chimney
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.
Please Note, this appliance has been tested by the manufacturers and works
on a 3.5m straight flue.
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 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 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°. 90° 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, also to permit visual checks on the integrity of the flue when the appliance is serviced.
