3.2.1.1
‘Hole-in-the-wall’ Installations
!
It is recommended that a hearth should be installed as in section 3.9 (See figure 1).
!
If a hearth is not fitted 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 100mm. 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 in the future then the distance from
the base of the fireplace opening in the wall to the floor level should be increased to at
least 175mm.
!
To protect from the risk of burns and ignition of clothing a tactile separator shall be
used. The hearth detailed in section 3.9 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.
!
If the lower part of the fascia (the firefront) is free standing, the recommended
reduced hearth depth is 100mm.
This is necessary to support the
firefront (See figure 5 for
appliance dimensions).
