There must be a clearance of at least 150 mm at each
side (back and sides) of the appliance in accordance
with the below recommandations from a non
combustible wall. This distance must be extended to
a minimum clearance of 650 mm side and 700 back
from any combustible material.
If any part of the back or sides of the appliance lies
within 150 mm horizontally of the wall, than the wall
should be of solid non-combustible construction at
least 50 mm thick from level to a level of 200 mm
above the top of the appliance and 1200 mm above
the hearth.
Il however, any part or sides of the appliance lies
within 50 mm of the wall, then the wall should be of
solid non-combustible construction at least 200 mm
thick from floor level to a level of 300 mm above the
top of the appliance and 1200 mm above the hearth.
Where the hearth itself in at least 150 mm from an
adjacent wall.
There is no requirement for protection of the wall. It
should be noted that these thicknesses of solid non-
combustible material can be substituted by thinner
material if the same overall level of protection can be
achieved.
When using a single wall flue pipe, there must be
a clearance (A) of at least three times its diameter
(B) from any combustible materials. If the appliance
has to be located in an opening, this distance must
be extended to a minimum clearance (A) of 450 mm
from the pipe or the stove body to any combustible
materials.
Hearth :
The appliance must stand on a fireproof
hearth. It is possible to provide a hearth made of
non combusible board/sheet material or tiles at least
12 mm thick (C). Constructional hearths should be
constructed of solid non combustible material at least
125 mm thick (including the thickness of any non
combustible floor under the hearth).The hearth must
protrude at least 300 mm in front of the stove and
150 mm each side. Hearths are provided to prevent
combustion appliances setting fire to the building
fabric and furnishings and to limit the risk of people
being accidentally burnt.
Therefore, they should be separated from adjacent
combustible materials and should be satisfactorily
delineated from surrounding floor finishes (carpets
etc.) as follows.
Combustible material should not be placed under a
constructional hearth for a solid fuel appliance within
a vertical distance of 250 mm from the upper surface
of the hearth, unless there is an airspace of at least
50 mm between the combustible material and the
underside of the hearth.
Where a superimposed hearth has been placed onto a
constructional hearth, combustible material placed on
or besid the constructional hearth should not extend
under the superimposed hearth by more than 25 mm
or closer to the appliance than 150 mm.
Ensure that the hear th (super imposed or
constructional) is suitably delineated to discourage
combustible floor finishes from being laid too close to
the appliance, by marking the edges or providing a
change of level.
Position the appliance on the hearth such that
combustible marerial cannot be laid closer to the base
of the appliance than :
(a) At the front, 300 mm if the appliance is an open
fire or stove which an, when opened , be operated as
an open fire, or 225 mm in any other case ;
(b) At the back and sides, 150 mm or in accordance
with the recommendations below which relate to
distance from hearth to walls. Please refer to section J
of the Building regulations.
When using a single wall flue pipe, there must be a
clearance (A) of at least 450 mm from any combustible
materials (timber mantel, girder).
