Fitting the Flue (Cont)
5. Mark dimension ‘Y’ on the flue as shown (Fig. 23).
Carefully cut the waste material from the flue,
ensuring that the ducts are square and free from
burrs.
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. 24).
8. Remove the flue elbow and insert the flue through
the hole in the wall. Refit 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. 25).

10. Ensure that the terminal is positioned with the
slots to the bottom (Fig. 25a).
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 7.9 & 7.10).
