Installation - Tiled Roof
STEP 1
Select a suitable position
along the roof that has no
obstructions below the tiles
(such as a rafter or cross
brace).
IMPORTANT: It is
recommended that the
ventilator be installed
along the 3rd or 4th row of
tiles from the ridge. Lower
positions will return lower
vent performance and
increase the risk of leakage
in heavy rain.
The installation higher than the third row of tiles down from
the ridge may damage the ridge tile pointing and is NOT
recommended.
STEP 2
Positiontheashingin
the desired location so
that the tiles that need to
be cut or removed can be
determined. Ensure bot-
tomedgeoftheashing
passes the lower tile edge
which will be folded later
to form a seal.
Mark-out the position to
either remove and/or cut
the required tiles.
Depending on roof construction, a tile batten may be obstructing
the throat opening of the vent. This batten can be left in place with
the ventilator sitting above it.

STEP 3
Cut the tiles marked ear-
lier using a grinder being
careful not to crack the
tile.
STEP 4
If the roof is sarked, cut
sarking in a cross and fold
back onto itself to give
an opening to match the
vent’s throat diameter.
Tape the corners to the
surrounding sarking with
foil tape to prevent them
fouling the ventilator.
