STEP 9
Select a suitable position
for the ventilator, keeping in
mind that the ceiling grille
needs to be installed in
the ceiling almost directly
below.
It is also recommended that
the ceiling grille be installed
somewhere near the centre
of the building, away from
windows or other openings.
Slip the top edge of the
flashing under the ridge cap
and mark position.
STEP 10
Remove the ventilator
and cut a 410mm square
hole around the centre of
the position marks.
Ensure that the flashing covers the roof corrugations or ribs
equally and that it is located between roof rafters.
