2.
INSTALL THE BOILER
a.
Fit the boiler in accordance with the installation instructions supplied with the CD boiler - sections 4.1 to 4.5.
b.
Use the template (supplied with the boiler) to mark the flue position and cut a 110 mm diameter flue hole (or use a
107 mm core drill).
Notes: a. Ensure the hole is cut horizontally.
b. If the Easy-Flue is to be extended or is being fitted internally, a 130 mm diameter flue hole is required
(refer to section 3, paragraph (c) or section 4).
3.
FIT THE FLUE
The following procedure applies to fitting an Alpha CD Easy-Flue to both rear or side exit flue - horizontally only.
Note: If extending the Easy-Flue refer to section 4.
a.
Determine the overall length (L) of flue required, (see Fig. 3) as follows:-
Rear flue
L = wall thickness (B) + 170 mm
Side flue
L = wall thickness (B) + distance between boiler and wall (C) + 230 mm
b.
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.
c.
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 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.
d.
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.
e.
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.
f.
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 100 mm out of the wall and the inner duct of the terminal is positioned
correctly (see Fig. 5).
g.
Make good the inside wall by pushing the inside flue sealing collar up to the wall.
