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
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.
E n s u r e t h a t t h e h e a r t h ( s u p e r i m p o s e d o r
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.

clearance (A) of at least 450 mm from any combustible
materials (timber mantel, girder).
