fireback for a debris
catchment space. The
required fireplace, hearth,
debris catchment area and
clearance dimensions are
shown in figure 1.
4.2.1.1
‘Hole-in-the-wall’
installations.
!
It is recommended that
a hearth should be installed
as in figure 1.
If a hearth is not fitted, the
fire must be installed so
that the distance from the
base of the fireplace
opening in the wall to the
finished floor level is at
least 25mm. Where there
is no floor covering or
carpet and the floor is of a type that
is likely to be covered in such a
way then the distance from the
base of the fireplace opening in the
wall to the finished floor level
should be increased to at least
100mm.
!
To protect from the risk of
burns and ignition of clothing a
tactile separator shall be used. The
hearth detailed in section 4.9 meets
the requirements for a tactile
separator. If this is not used then a
672mm long fender, kerb,
horizontal bar, or other barrier,
being fixed not less than 50mm
above floor level and positioned
300mm in front of the fixing plane of the fire will meet the requirement.
