PREPARING THE WALL
IMPORTANT. Ensure that, during the cutting operation,
masonry falling outside of the building does not cause
damage or personal injury.
1. 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.
2. Drill 3 holes with a 7.5mm / 8mm masonry drill and
insert the plastic plugs provided, for the wall
mounting plate and the jacking screw plate.
Note.
If using the stand-off kit then drill 4 holes (choosing
one from each group but not the jacking screw).
3. Locate 2 No.14 x 50mm screws in the piping frame
(one at each side, in any of the 3 holes provided at
each side) and screw home.
Note.
If using the stand-off kit then locate the stand-off
channel and screw home.

SETTING THE FLUE - SIDE Wall thicknesses of 170 to 395mm
18
SETTING THE FLUE - REAR Wall thicknesses of 210 to 435mm
Notes.
a. If using the extension ducts go to Frame 18.
b. For shorter flue requirements use non telescopic B
Pack.
1. Measure and note wall thickness X. Refer to Frame 14.
2. Measure distance from side of boiler to inside of wall
and add to wall thickness X=L. Refer to Frame 14.
3. Add 115mm to dimension L and set telescopic flue
length as indicated in drawing.
4. Using a 3.5mm drill bit, drill two holes in outer air duct
taking care not to pierce plastic inner flue.
5. Fix to length using self tappers provided.
6. Seal outer air duct using the tape provided.
Notes.
a. If using the extension ducts go to Frame 18.
b. If the stand-off frame is used it is essential to add 33mm
to dimension X.
c. For shorter flue requirements less than 210mm, use non
telescopic B Pack.
1. Measure and note wall thickness X. Refer to Frame 12.
2. Add 75mm to dimension X and set telescopic flue length
as indicated in drawing.
3. Using a 3.5mm drill bit, drill two holes in outer air duct
taking care not to pierce plastic inner flue.
