2.13 CUTTING THE FLUE

CUTTING HORIZONTAL FLUE TERMINAL
(non-telescopic)
1. Measure the required cut flue length (A + 44 mm)
2. Measure from the outer terminal lip to the end of outer
tube. Mark the required cut length (A + 44 mm) around
the circumference of the outer tube and cut following the
mark to ensure it is cut square.
3. Mark and cut the inner tube 10 mm longer than the outer
Mark 2 Flush with
tube ensure the cut is square.

4. Remove all burrs on the inner and outer tube and place a
light chamfer on the inner tube to aid with assembly.

SETTING TELESCOPIC FLUE
1. Measure the required length (A + 44 mm)
+14 mm
2. Pull flue apart until the desired length is achieved
ensuring the stop mark is not visible.
3. Ensure both flue seams are at the top and the flue outlet
terminal is uppermost.
4. Drill a 3.5 mm hole through the small and large outer
tube using the pilot hole on the large outer tube.
5. Secure large and small outer tube using the screws
provided.
6. Seal the joint on the out tube with the tape provided.
7. Fit the internal and external wall seals.

FITTING THE FLUE THROUGH THE WALL
(Internal Installation)
Mark 2 Flush with
the inner wall seal
1. Measure the thickness of the wall.
2. To this measurement add 14 mm.
3. Make a mark on the flue shown as mark 1 (top right).
4. Make another mark on the flue a further 14 mm in shown
as Mark 2 above right.
5. Fit the external wall seal (black) to the flue terminal
ensuring it is fitted on the terminal outer lip seal.
Mark 1 Flush with inter wall
6. Fit the inner wall seal approximately 65 mm prior to Mark 2.

7. Place the terminal end of the flue into the 127 mm core
drilled centrally and slowly apply slight pressure and
move the flue up or down or side to side. This will cause
the external wall seal to fold in and allow the flue to pass
through the wall.

8. When the inner wall seal is flush against the wall pull

back the flue until Mark 1 is flush with the inner wall
surface.
9. Hold the flue steady and push the inner wall seal
towards the wall until Mark 2 is just visible.
FITTING THE FLUE THROUGH THE WALL
(External Installation)
1. Follow steps 1 - 5 from above.
2. Push the flue through the 127 mm core drilled hole from
the outside
3. Return inside the property and fit the inner wall seal to
10 mm

towards the wall until Mark 2 is just visible.
If Mark 1 is not flush with the inner wall surface and can be
seen prior to the wall surface, then the external wall seal
will have been dislodged and will require to be re-fitted. If
this situation occurs, then please start the process from the
beginning.
