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 a 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).
