15 PREPARING THE WALL
WARNING.
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 2 holes (see frame 14) with a 12 mm (1/2")
masonry drill and insert the plastic plugs
complete with hook screws, provided, for the
upper boiler bracket.
or
Drill 4 holes (see frame 14) with a 12 mm (1/2")
masonry drill for the stand-off kit.
16 CUTTING THE FLUE - REAR
Wall thicknesses of 114 to 620 mm
Note.
a.
If using the extension ducts go to Frame 20.
b.
If the upward routing pipe stand-off kit is used it is
essential add 50 mm to 'X' the measured wall
thickness when marking the flue (this will allow for the
fitted stand-off kit).
1.
Measure and note wall thickness X - Refer to Frame 12
2.
Add 90 mm (3 9/16) to dimension X and, measuring
from the groove, cut the outer tube only.
3.
To ensure the tube is cut square, mark the flue all the
way round.
4.
Cut the inner tube to a length 20 mm (3/4") longer to
aid engagement.
17 CUTTING THE FLUE - SIDE
Wall thicknesses of 114 to 580 mm
Note.
If using the extension ducts go to Frame 20.
1.
Measure and note wall thickness X - Refer to Frame 12
2.
Add 130 mm (5 1/8") to dimension X and, measuring
from the groove, cut the outer tube only.
3.
To ensure the tube is cut square, mark the flue all the
way round.
4.
Cut the inner tube to a length 20 mm (3/4") longer to
aid engagement.
Note.
If the terminal is to be sited within 25-40 mm of a corner or vertical
pipe then the hole MUST be accurately cut.
