Fireplace Preparation; The Hearth And Back Panel - Valor Fires 963 Installer And Owner Manual

4.7 Fireplace preparation.

4.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
4.7.2 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.
4.7.3 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.
4.7.4 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 2). 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.
4.7.5 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.

4.8 The hearth and back panel.

The appliance must be mounted behind a non-
combustible hearth unless the conditions of
section 4.10.1.1 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 appliance must not stand on combustible materials or carpets.
