Chimney Preparation; Fireplace Preparation - Valor BRAVA 348 Installer And Owner Manual

5.4.2 An extractor fan may only be used in the same room as this appliance, or in
any area from which ventilation for the appliance is taken, if it does not affect the safe
performance of the appliance. Note the spillage test requirements detailed further on
in this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.
5.4.3 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by
heat. They may scorch or become discoloured when close to a heating appliance.
Please bear this in mind when installing.

5.5 Chimney preparation.

5.5.1 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.
5.5.2 Any chimney dampers or restrictors should be removed. If removal is not
possible they must be fixed in the open position.

5.6 Fireplace preparation.

5.6.1 The appliance can be fitted to a purpose made proprietary class "O" 150°C
surround.
5.6.2 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
5.6.3 The front of the fireplace should be flat over an area sufficient to ensure a good
seal with the closure plate. The flat surface should extend for a height equal to that of
the closure plate plus 20mm and for a
width equal to that of the closure plate
plus 40mm.
5.6.4 If the fire is to be fitted against a
wall with combustible cladding, the
cladding must be removed from the area
shown in figure 1.
5.6.5 The space between the fireplace
front face and the back of the fascia
must not be filled in.
5.6.6 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.
