14 PREPARING THE WALL
IMPORTANT.
Ensure that, during the cutting operation, masonry
falling outside of the building does not cause damage
or personal injury.

Cut the flue hole (preferably with a 5" core boring
tool), ensuring that the hole is square to the wall.
Both wall faces immediately around the cut hole
should be flat.

Wall thicknesses of 114 to 600mm
Notes.
a.
If using the extension ducts go to Frame 17, 18 and 19.
b.
If the stand-off frame is used it is essential add 33mm to
'X' the measured wall thickness when marking the flue
(this will allow for the fitted frame).
1.
Measure and note wall thickness X. Refer to Frame 11.
2.
Add 105mm (4
1/8
") to dimension X and, measuring from
the ring, cut both outer and inner tube. Ensure support
spring clip is in position to facilitate cutting.
3.
To ensure the tube is cut square, mark the flue all the way
around.
16 CUTTING THE FLUE - LH OR TO RH SIDE
Wall thicknesses of 114 to 420mm LH side or to 630mm RH side
Note.
If using the extension ducts go to Frame 17,
18 and 19.
1.
Measure and note side flue length L or R.
Refer to Frame 11.
2.
Add 284mm (11
3
/
16
") to dimension L or 72mm
(2
13
/
16
") to dimension R and, measuring from
the ring, cut both outer and inner tube. Ensure
