FIT THE FLUE - Figs. 5.5 and 5.6
The following procedure applies to fitting an Alpha CD Easy-Flue to both rear or side exit flue - horizontally only.
1.
The CD Easy-Flues are suitable for use in the flue length ranges shown in the tables below.
Note: Where the length is less than the minimum or more than the maximum, refer to Section 5.7.

(B)
Note: Add 45 mm to
dimension B if the wall jig is
used.
2.
Determine the overall length (L) of flue required, (see Fig. 5.7) as follows:-
Rear flue
Side flue
3.
Adjust the telescopic section of the flue to the distance 'L', ensuring that the two labels marked 'TOP' are aligned, then
seal and secure the joint between the ducts with the sealing tape supplied.
Note: Always ensure that there is a minimum overlap of 25 mm when fully extending the telescopic section.
4.
Pass the flue assembly through the wall (from inside or outside).
Note: Internal fitting - If there is no access to make good the outside wall, locate the outside (black) flue sealing collar
onto the outer duct of the flue immediately before the terminal grille onto the location provided. Push the flue assembly
through the 130 mm flue hole, so that the collar completely passes through the wall. Then pull the flue assembly back into
the correct position. Visually check that the collar is sealing the outside wall and that it is not restricting any of the openings
of the flue terminal.
Note: Silicone grease or other lubricants must not be used on the flue joints or seals.
Where a flue terminates less than 150 mm below a gutter, eaves or other obstructions it is possible to extend the flue to
allow the flue termination to clear the obstruction, providing the flue is not extended beyond the first joint. For situations
below balconies or large eaves where extensions may be required, the flue must be supported using the correct
brackets. Alternatively plume management components can be used with supports where necessary.
All joints between flue sections should be connected using the clamps provided. It is not required to add additional
screws through the clamps and into the flue sections.
