INSTALLATION

• Plumb the lower connector against the existing wall so that it will be central to the new wall. 
• Mark the position of the fixing holes. Each connector should be fixed at three points, the first and last slot and in the centre. Ensuring that one fixing is at the point where the two connectors slot together and overlap. Fixings should be into brickwork and not mortar joints. 
• Drill and plug using an 8mm masonry drill bit and the plugs provided. 
• Fix the bottom two holes lightly using the stainless steel coach screws and washers. 
• Slot the upper connector into the lower one and repeat the above stages. The upper connector can be cut to length if required. 
• Tighten all fixings using a 10mm socket or box spanner. 
• Build wall in the conventional way with a full mortar joint between the existing and the new wall. Ties should be inserted at a maximum of 300 centres, every third brick course or each block course. Ensure that the ties and connectors are completely embedded with mortar.

• Ensure that the bottom edge of the connector is above the damp-proof course.
• A weather seal of approximately 10mm should be created between the connector and the existing wall using a flexible mastic sealant or a compressible sealing strip.
• Consult your Local Authority, as additional weather proofing may be required in accordance with local building regulations.
