3.10.1.1
‘Hole-in-the-wall’ Installations.
It is recommended that a hearth should be installed as in section 3.8 (See figure
4).
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 3.8 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.
3.10.2
Metal flue box and hearth.
The appliance can be installed to a fireplace incorporating a metal flue box complying
with the constructional requirements of the current edition of BS 715 and with a flue
conforming to BS EN 1856 part 1. The dimensions of the flue box must conform to
those shown in figure 6.
Important Note
:
The top surface of the metal
flue box must be covered with
a 100mm layer of mineral wool
or equivalent insulation (See
figure 6).
