Chimney Preparation; Fireplace Preparation - Valor 762 Installer And Owner Manual

5.6 Chimney preparation.

5.6.1 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.
5.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.

5.7 Fireplace preparation.

5.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
5.7.2 The fireplace floor should be reasonably flat to ensure that a good seal with the
convection box can be made.
5.7.3 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.
5.7.4 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.
5.7.5 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.
