INSTALLER’S GUIDE

2.8
If the appliance is intended to be installed to a chimney which 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.
2.9
If the fireplace opening is an underfloor draught type, it must be sealed to stop any
draughts.
2.10
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 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
.
2.11
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.
The fireplace floor should be reasonably flat to ensure that a good seal with the
convection box can be made.
2.12
The minimum height from the top surface of the hearth to the underside of any
shelf made from wood or other combustible materials is shown in graph 1.
2.13
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.
2.14
This appliance must not be installed in any room which contains a bath or shower or
where steam is regularly present.
2.15
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.
