Fixing the first wall bracket No 2 Draw a horizontal line through the vertical at 15mm from the ceiling as illustrated, or from a horizontal line drawn between the top of two adjoining wall cabinets. Place the top edge of the bracket against the line, aligning the centre of the bracket with the vertical line. If, the alignment is correct mark the centres for the keyhole fixing screws (not supplied) as illustrated in Fig. 3. Fixing the second wall bracket No 2 Draw a horizontal line through the vertical at X. X is determined by the height of the upper chimney. Place the bottom edge of the bracket against the line, aligning the centre of the bracket with the vertical line. If, the alignment is correct mark the centres for the keyhole fixing screws (not supplied) as illustrated in Fig. 4. Splashback (Optional) When the splashback is to be fitted, the distance between the cooker hood and the cooking appliance will be determined by the height of the splashback B, as illustrated in Fig. 4. Position the splashback on the worktop, ensuring the worktop is level first, as illustrated in Fig. 4; then holding the splashback against the wall mark the position of the holes for the fixing screws. The splashback must be fitted before installing the cooker hood. If the splashback is to be fitted in conjunction with a slot-in cooker, or free standing appliance then it will be necessary to fix the splashback to the wall using both the top and bottom wall fixing screw holes. Drill the holes for the fixing screws using an 8mm masonry drill and fix the wall brackets. Note: If the hood is to be installed onto a hollow construction or plaster or partition board wall then special fixing screws will be required (not supplied).
