4.6 Chimney preparation.
4.6.1
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.
4.6.2
Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
4.7 Fireplace preparation.
4.7.1
If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
4.7.2
The fireplace floor should be reasonably flat to ensure that the convection box
can be installed without it rocking and so that a good seal can be made at the bottom
front of the box.
4.7.3
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.
4.7.4
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. If the cladding projects forward
from the fixing plane of the fire the
clearance at the top of the appliance must
be increased to a minimum 15mm. This
will allow for fascia removal.
4.7.5
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.
