5. FIREPLACE CHECK

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 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 fascia. The cladding must
also not touch the fascia (See figure 4). We suggest that the 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 wall fixing plugs and wood screws. 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
