5. Mark dimension 'Y' on the flue as shown (Fig. 37).
Carefully cut the waste material from the flue, ensuring
that the ducts are square and free from burrs.

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. 38).
8. Insert the flue through the hole in the wall. Fit the
elbow to the boiler adaptor, ensuring that it is pushed
fully in.
