4.7 REDUCING THE FLUE - Fig. 20
When the flue length required is less than the minimum stated in Section 4.6, paragraph 1, refer to Fig. 20.
Discard the first telescopic section (
not
the section with the terminal) of the Easy-Flue 1000 mm or 500 mm and cut to the
required length.
Note:
Ensure that all cuts are square and free from burrs.
Once assembled with the components pushed home, the flue is fully sealed.

5. Position the seal and clamp (two screws) supplied, over the bend. Fit the bend to the boiler and rotate to the correct position.
Secure in position using the seal and clamp, ensuring the seal is located centrally over both the bend and boiler adaptor.
6. Fit the inside flue sealing collar over the Easy-Flue. Fit the outside flue sealing collar onto the flue immediately before
the terminal grille onto the location provided.
7. Slide the clamp (three screws) over the outer duct and pull the flue assembly towards the bend, locating the inner
duct into the seal joint on the bend. Ensure the labels marked 'TOP' are positioned at the top before securing the flue
assembly to the bend with the clamp (three screws) located centrally over the joint.
Note:
Check the flue terminal protrudes 90 mm out of the wall and the inner duct of the terminal is positioned correctly
(see Fig. 19).
8. Make good the inside wall by pushing the inside flue sealing collar upto the wall.
