4.1
4.1.1
Fireplace size
The fireplace must comply
with the requirements
described in section 2.2.
This will probably entail
removing the fireback and
infill material behind the
fireback. The debris
catchment area shown in
figure 7 must be kept clear
of obstructions.
4.1.2
Fireplace general
condition
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. 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. If the appliance is to
be fitted against a wall with combustible cladding, the cladding must be removed from
the area covered by the outer surround. The cladding must also not touch the surround.
(See figure 4). We suggest that the actual surround 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.
4.1.3 Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1)
By fixing to the fireplace front surround.
2)
Using concealed tension cables fixed to the rear of the fireplace opening together
with secondary fixing to the fireplace floor.
The methods are detailed in section 8 of this manual. Before selecting the retention
method, consult with the customer. Method 2 is provided for instances where drilling
holes in the front surface of the fireplace surround is unacceptable to the customer or
otherwise impractical.
N.B. It is unwise to attempt to drill into marble without the proper
tools and equipment
