10.7 Fitting the Flue (Cont)
5. Mark dimension ‘Y’ on the flue as shown (Fig. 36).
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. 37).
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. 38).
10. Make good between the wall and air duct outside the
building.
11. Fit the flue trim if required, and if necessary fit a terminal
guard (see Section 8.8 & 8.9.
