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
Chimney Connection
Flue Diameter 150mm (175cm2)
IMPORTANT: When installing the UNIQ 15, 16 & 20 wood stoves remove steel retaining bar across flue exit.
Remove bolts and take out bar replace and bolt cast into place.
In order for the stove to perform satisfactorily the chimney height must be sufficient to ensure an adequate
draught so as to clear the products of combustion and prevent smoke problems into the room.
Minimum draft: UNIQ 15, 16, 20 stove has been tested with a draft of 12 Pa. Maximum draft 25 Pa.
Flue gas flow 4.2 g/sec.
Flue gas temperature 240°C. approximately 12 Pa.
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.
The outlet from the chimney should be above the roof of the building in accordance with the provisions of Build-
ing 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 160 mm x 160 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 instal-
lation to clear any soot falls which may have occurred due to the difference in combustion between the stove and
yes
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.
