In addition it is strongly recommended that any furniture or other combustible materials
are kept at least 900mm clear from the front of the stove.
Combustible Shelves and Beams
Due to the fact that combustible shelves, timber fireplaces and beams have potentially
thousands of possible configurations in conjunction with stoves that are outset or
inserted partially or fully into chambers, it is not possible to give firm guidance on
dimensions to these features. As a guideline, materials that are in ‘line of sight’ to the
stove are more likely to overheat due to direct radiation from the stove body than
materials that are not in ‘line of sight’ (e.g. with stove fully inside a chamber). Materials
above the stove are more likely to overheat than materials alongside or below. A
guideline limiting temperature for solid timber (not surface finishes) is approximately 80-
85 degrees C with a normal ambient room temperature. Temperatures of combustible
materials can be substantially lowered with a simple heat shield constructed of a non-
combustible material and small air gap between the shield and combustible material.
Distances from NON-combustible materials:
The stove can be recessed in a suitable sized non-combustible fireplace but a
permanent free air gap of at least 50mm must be left around the sides and top and at
least 50mm at the back of the stove to obtain reasonable heat output and for access to
the stove for removal and maintenance. A clearance of 150mm will give a better heat
output. A clearance of 120mm is desirable on the right side of the stove to fully operate
the grate de-ashing mechanism.
All non-combustible walls closer than 400mm to the stove should be at least 75mm
thick. For practical reasons the back wall of the fireplace recess and the hearth should
ideally be made of non-combustible material.
4.6 Hearths:
These freestanding stoves do not require a constructional hearth beneath them as they
do not cause the floor temperature to exceed 100 degrees C.
Note: the solid fuel hearth
heat shield supplied fitted beneath the stove must remain in place when using
smokeless or any coal fuels to ensure compliance with this requirement
– this part is
supplied pre-fitted under the stove body. Hearths must be level and square to any back
panel or the wall. In any case a non-combustible superimposed hearth extending fully
underneath the stove and forming an apron of at least 225mm at the front of the stove
and 150mm on either side must be provided. The superimposed hearth must not be less
than 12mm thick and must have a clearly defined edge (change of level) to discourage
placing of any combustible materials on or partially over it.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the
existing construction does not meet this requirement, suitable measures (e.g. load
distributing plate) should be provided to achieve it.
