6. FIREPLACE CHECK
6.1 Fireplace check.
6.1.1
Fireplace size
The fireplace must comply with
the requirements described in
section 4.2. 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.
6.1.2
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.
6.1.3
Soundness for appliance attachment
A primary method of retaining the appliance is provided. This involves using
concealed tension cables fixed to the rear of the fireplace opening together with
secondary fixing to the fireplace floor. This method is detailed in section 10 of this
manual. This method is particularly useful 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
.
Make sure that the areas at the back and towards the centre of the fireplace floor are
sound enough to take the eyebolts and screws. If these areas have deteriorated due
to prolonged use, they should be made sound with suitable cement.
6.1.4
Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a 100mm
layer of mineral wool or equivalent insulation (See figure 2).
