3.6 Chimney preparation.
3.6.1
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.
3.6.2
Any chimney damper or restrictor should be removed. If removal is not
possible, they must be secured in the open position.
3.6.3
The flue must not be used for any other appliance or application.
3.7 Fireplace preparation.
3.7.1
If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
3.7.2
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.
3.7.3
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. The
fireplace floor should be reasonably flat to
ensure that a good seal with the convection
box can be made.
3.7.4
If the appliance is to be fitted against
a wall with combustible cladding, the
cladding must be removed from the area
shown in figure 1.
3.7.5
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.
3.7.6
The appliance must not stand on combustible materials or carpets
.
