Fit The Flue - Alpha InTec 50CS Installation, User And Servicing Instructions

1.6 FIT THE FLUE - FIGS. -5 ANd 1-6
The following procedure applies to fitting an
Alpha CD Easy-Flue to both rear or side exit
flue - horizontally only.
- The CD Easy-Flues are suitable for use in the
flue length ranges shown in the tables in Figs
1-5 and 1-6.
Note: Where the length is less than the
minimum or more than the maximum, refer
to Section 1.7.
(B + C)
Side Flue
Boiler
- Determine the overall length (L) of flue required, (see Fig. 1-7) as follows:-
Rear exit L = wall thickness (B) + distance between boiler and wall (C) + 230 mm
left exit L = wall thickness (B) + distance between boiler and wall (C) + 442 mm
Right exit L = wall thickness (B) + distance between boiler and wall (C) + 58 mm
Seal joint with tape
- 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.
- 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. See Fig. 1-8.
