Fireplace Check - Baxi Fires Division 740FS Installer's Manual

5.1 Fireplace check.

5.1.1 Fireplace size.
The fireplace must comply
with the requirements
described in section 3.2.
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.
5.1.2 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
fascia. The cladding must also not touch the fascia (See figure 4). 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.
5.1.3 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 9 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.
If method 2 is chosen, make sure that the areas at the back and towards the centre of the
