5.1 Floor protector requirements
This appliance has been tested as required under ADJ Page 37 Item 2.23a and maximum temperature rise
recorded at 37°C. Only a hearth made of non-combustible board/sheet materials or tiles at least 12mm thick
are required.
The heater should always be installed on top of its leg base due to high temperaturessustained over long
periods of use. It is recommended that the appliance be secured to the floor protector to ensure stability with
the brackets supplied.
In situations where the stove is to be fitted into a brick or non-combustible recess, we recommend that the stove
is installed with at least 100mm clearance to the wall, this will allow room air to circulate around the stove; also
the maintenance of the outside stove is easier. When applied to masonry, a layer of wallpaper is normally
classified as a non-combustible surface.
5.2 On the floor
National and Local Building Regulations must again be observed when considering the type, thickness and area
of the hearth to be used in the installation. Max Hearth temperature under safety test was 37°C. One should of
course always make certain that the underlying floor surface can bear the weight of the stove.
5.3 Clearance to furniture and soft furnishings
We recommend that the stove be installed 700 mm from furniture. Serious consideration should also be given to
positioning of any furniture that could be adversely affected by heat. The clearances to combustible materials in
front of the stove should be a minimum of 700 mm. When lit, a wood-burning stove gets hot and therefore
adequate protect must be provided, particularly in situations where there is a safety risk to children or the infirm.
A suitable safety guard around the stove should be considered.
6. HETAS amendments
6.1 More detailed advice about existing chimney usage
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.
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.
