STOVE PERFORMANCE
In the UK the stove has been approved by HETAS Ltd as an intermittent operating
appliance for burning wood logs only.
It should be noted that it is an offence to burn wood logs in this stove if it is installed within
a Smoke Control Area in the UK, unless it has been accredited as a Smoke Control
Exempt appliance (Check with your supplier/installer).
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

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.
Please Note, this appliance has been tested by the manufacturers and works on a
3m 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.
