13 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 an 8mm masonry drill and
insert the plastic plugs, provided, for the wall
mounting plate.
14 SETTING THE FLUE - REAR
Notes.
a. If using the extension ducts go to Frame 16.
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).
c. For wall thickness less than 200mm use none telescopic
b pack.
1. Measure and note wall thickness X. Refer to Frame 10.
2. Add 85mm (4") 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.
4. Fix to length using self tappers provided.
5. Seal out air duct using the tape provided.
15 SETTING THE FLUE - SIDE
Note.
a. If using the extension ducts go to Frame 16.
b. For shorter flue requirements use non telescopic
b pack.
1. Measure and note wall thickness X. Refer to Frame 10.
2. Measure distance from side of boiler to inside of wall
and add to wall thickness X = L. Refer to Frame 10.
3. Add 156mm to dimension L, hand 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.
