and having a minimum
effective flue height of
3m (10ft). A masonry
chimney having a

‘Hole-in-the-wall’ Installations
!
It is recommended that a hearth should be
installed as in section 3.9 (See figure 1).
!
If no hearth or a reduced depth hearth is
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 72mm. Where there is no floor

that is likely to be covered in such a way in
the future then the distance from the base of
the fireplace opening in the wall to the
finished floor level should be increased to at
least 147mm.
!
If the lower part of the fascia (the
firefront) is free standing, the recommended
reduced hearth depth is 100mm. This is
