then the distance from the base of the fireplace opening in the wall to the floor
level should be increased to at least 175mm.
Adorn, Dream, Visage, Obsession and Eternal firefront
If when using the Adorn, Dream, Visage, Obsession and Eternal firefronts 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 100 mm. It is recommended that the reduced hearth has a depth from the
fixing plane of the fire of 100mm minimum. This is necessary to support the
lower front casting. 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 7.
The top of the metal flue box
must be covered with a 100mm
layer of mineral wool or
equivalent insulation (See figure
7).
Important Note: Where the flue
box has a base sheet that is
single wall (i.e. a single metal
sheet) the flue box must be
mounted on a non-combustible
hearth. The hearth material must
be at least 12mm thick.
