The flue must conform to BS 5440: Part 1 in design and installation.
The flue, measured from the bottom of the fireplace opening to the bottom of the
terminal, shall be not less than 3m in actual vertical height. When calculated in
accordance with BS 5440: Part 1 Annex A, the minimum
equivalent
height of the flue
shall be 2.0m of 125mm dia. flue pipe.
3.5
The flue must not be used for any other appliance or application.
3.6
Any chimney dampers or restrictors should be removed. If removal is not possible
they must be fixed in the open position.
3.7
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.
3.8
If the fireplace opening is an underfloor draught type, it must be sealed to stop any
draughts.
3.9
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 appliance must not stand on combustible materials or carpets (See figure 1)
.

The front face of the fireplace should be reasonably flat over the area covered by
the convector 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 convector box can be made.
3.11
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.
3.12
The appliance must not be installed in any room, which contains a bath, or shower
or where steam is regularly present.
3.13
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
