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 hotbox 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 hotbox 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
.
If method 1 is chosen, make sure that the front surround area is sound enough to take the
Fibre plugs and woodscrews. If necessary, make sound with a suitable cement.
