4.6 Chimney preparation.4.6.1 If the appliance is intended to be installed to a chimney that was previouslyused for solid fuel, the flue must be swept clean prior to installation. All flues shouldbe inspected for soundness and freedom from blockages.4.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,they must be secured in the open position.4.7 Fireplace preparation.4.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stopany draughts.4.7.2 The fireplace floor should be reasonably flat to ensure that the convection boxcan be installed without it rocking and so that a good seal can be made at the bottomfront of the box.4.7.3 The front face of the fireplace should be reasonably flat over the area coveredby the convection box top and side flange seals to ensure good sealing. These facesshould be made good if necessary.4.7.4 If the appliance is to be fitted against a wall with combustible cladding, thecladding must be removed from the areacovered by the fascia. The cladding mustalso not touch the fascia (See figure 1).We suggest that the actual fascia is usedas a template to mark the area forcombustible cladding removal and thatthis area is increased by at least 2mm allround. If the cladding projects forwardfrom the fixing plane of the fire theclearance at the top of the appliance mustbe increased to a minimum 15mm. Thiswill allow for fascia removal.4.7.5 If the fireplace opening is greaterthan the acceptable dimensions given inthis guide, do not use the back of a firesurround or marble to reduce the opening.This may cause cracking of the surroundback or marble.Page 11© Baxi Heating U.K. Limited 2010.INSTALLER GUIDEFigure 1.
