The debriscatchment area shown infigure 7 must be kept clearof obstructions.6.1.2 Fireplace generalcondition.The fireplace floor shouldbe reasonably flat to ensurethat the convection box canbe installed without itrocking and so that a goodseal can be made at the bottom front of the box. The front face of the fireplace shouldbe reasonably flat over the area covered by the convection box top and side flangeseals to ensure good sealing. These faces should be made good if necessary. If theappliance is to be fitted against a wall with combustible cladding, the cladding must beremoved from the area covered by the fascia. The cladding must also not touch thefascia (See figure 4). We suggest that the actual fascia is used as a template to markthe area for combustible cladding removal and that this area is increased by at least2mm all round.6.1.3 Soundness for appliance attachmentTwo 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 togetherwith secondary fixing to the fireplace floor.The methods are detailed in section 10 of this manual.
