1.Cut a hole in the external wall which the concentric flue assembly will pass through. The hole should allow the flue to fall back to the boiler at an angle of at least 1.5°.
2.When completed the terminal must be at least 2 metres above ground level (Fig. 19).
3.Measure and cut to size the concentric assembly and any extensions that are being used.
4.Insert the concentric assembly through the hole from outside the building.
5.If required, the flexible flue trim should be fitted prior to this as it cannot be fitted after. Use the large ‘Jubilee’ clip to secure the trim to the flue (See Fig. 20, trim shown dotted), with the screw part of the clip at the bottom.
6.Connect any extensions or elbows that are being used to the concentric assembly. Engage the extension, elbow or concentric assembly in the boiler flue elbow. Fit the boiler flue elbow to the boiler adaptor.
7.Ensure that the concentric assembly and any extensions fall back to the boiler at an angle of at least 1.5° and that the external air inlet is to the bottom.
8.Use suitable brackets to support the concentric assembly and any extensions, and make good inside and outside.
9.The 60Ø exhaust can now be fitted. Slide the adaptor over the plain end of the 60Ø exhaust (Fig. 22) and engage the exhaust in the terminal. Slide the adaptor down over the spigot. Mark and drill the adaptor, using a 2mm bit, as shown in Fig. 21. Secure the adaptor to the spigot using one of the screws supplied.
10.If it is necessary to shorten the 60Ø exhaust or any of the extensions, the excess material must be cut from the plain end of the pipe.
11.Determine the position of the 60Ø exhaust and mark on the wall a suitable position for the support bracket. If extensions are being used, a support bracket is supplied in each kit.
12.Drill the wall, and fit the bracket(s) using the plug and screw provided.
