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.

IMPORTANT: When installing the UNIQ 37 wood stoves remove steel retaining bar across flue exit. Remove bolts and take out bar replace and bolt cast onto
collar.
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 37 stove has been tested with a draft of 12 Pa. Maximum draft 25 Pa.
Flue gas flow 7.0 g/sec.
Flue gas temperature 303°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 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 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 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.
If it is found that there is excessive draught in the chimney then either an adjustable flue damper or alternatively a draught stabiliser should be fitted. The adjustable flue damper
should not close off the flue entirely but should in its closed position leave a minimum continuous opening free area of at least 20 % of the total cross sectional area of the flue
or fluepipe.
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the chimney and connecting flue pipe.
Distance to Combustible materials
Combustible materials 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.
