FLUE OUTLET
17 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 7mm (
1/4
") 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.10 x 2" 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.

Note.
If using the extension ducts go to Frame 20.

3/4
") longer to aid
engagement, using the cardboard support.

Add 90mm (3
1/2
