The Hearth - Valor Homeflame Dream Installation And Owner's Manual

3.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
3.7 Fireplace preparation.
3.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
3.7.2 The fireplace floor should be reasonably flat to ensure that the convection box
can be installed without it rocking and so that a good seal can be made at the bottom
front of the box.
3.7.3 The front face of the fireplace should be reasonably flat over the area covered
by the convection box top and side flange seals to
ensure good sealing. These faces should be made
good if necessary.
3.7.4 If the appliance is to be fitted against a wall
with combustible cladding, the cladding must be
removed from the area covered by the fascia. The
cladding must also not touch the fascia (See figure
1). We suggest that the actual fascia is used as a
template to mark the area for combustible cladding
removal and that this area is increased by at least
2mm all round.
3.7.5 If the fireplace opening is greater than the
acceptable dimensions given in this guide, do not
use the back of a fire surround or marble to reduce
the opening. This may cause cracking of the
surround back or marble.

3.8 The hearth.

The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 3.10.1.1 are met (N.B. conglomerate marble hearths are
considered as non-combustible). The appliance can be fitted to a purpose made
proprietary class "O"-150°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.
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.
The appliance must not stand on combustible materials or carpets.
