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
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.
