6.The inner flue duct support bracket may be in the waste portion of the flue. In this case retrieve the bracket before discarding the waste.

7.Take the inner flue support bracket (if not already fitted) and engage it over the flue duct. This will centralise the flue and air ducts, and ease assembly (Fig. 50).

Apply Lubricant for ease of assembly.

8.Insert the flue through the hole in the wall. Fit the elbow to the boiler adaptor, ensuring that it is pushed fully in.

9.Draw the flue back through the wall and engage it in the elbow. It may be necessary to use soap solution or similar to ease assembly of the elbow adaptor and flue (Fig. 51).

10.Ensure that the terminal is positioned with the slots to the bottom (Fig. 52).

IMPORTANT: It is essential that the flue terminal is fitted as shown to ensure correct boiler operation and prevent water entering the flue.

11.Make good between the wall and air duct outside the building.

12.Fit the flue trim if required, and if necessary fit a terminal guard (see Section 8.8 & 8.9).

13.Once the length of the vertical concentric extension has been determined mark and carefully cut off the excess material. The cut end MUST be square and free of burrs to ensure correct insertion into the boiler adaptor.

14.Measure 25mm from the end of the flue extension and apply a length of tape around the outer duct (Fig. 53).

15.Engage the extension into the adaptor up to this position (Fig. 54). Once the installation of the flue is complete and all support brackets are securely in place remove the tape.
