Any chimney damper or restrictor should be removed. If removal is not possible, they
must be secured in the open position.
If the appliance is intended to be installed to a chimney that was previously used for
solid fuel, the flue must be swept clean prior to installation.
All flues should be inspected for soundness and freedom from blockages.
4.3
If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
4.4
The appliance must be mounted behind a non-combustible hearth (N.B.
conglomerate marble hearths are considered as non-combustible). The appliance can be
fitted to a minimum class “O” – 100°C surround. The hearth material must be at least
12mm thick. The periphery of the hearth (or fender) should be at least 50mm above
floor level to discourage the placing of carpets or rugs over it (See figure 1 or 2).
The surface of the hearth must be sufficiently flat to enable the bottom of the front
surround and the bottom front cover to be aligned horizontally. Any excessive
unevenness (uneven tiles, Cotswold stone, etc.) should be rectified.

casting.
!
If a hearth is not fitted or if 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 75mm. 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 finished floor level should be
increased to at least 150mm.
!
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.
!
To protect from the risk of burns and ignition of clothing a tactile separator shall be
used. The hearth detailed in section 4.4 meets the requirements for a tactile separator. If
this is not used then a 680mm 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.
The tactile separator can also take the form of a canopy, being fixed not more than
1000mm above floor level and positioned 300mm in front of and 150mm beyond the
edge of any naked flame or incandescent part of the fire bed.
