!
Icon firefront
!
If when using the Icon firefront 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 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.
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 3.9 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.
