INSTALL AT YOUR OWN RISK
The installation of this product may be dangerous and includes the potential
risk of death, personal injury or property damage. Please be aware of the
following before installing this product.
• Follow any State or Territory, Regulator or OH&S guidelines for working
 atheight(e.g.roofwork),electrical,workinginconnedspace.
• Installation may require working at height and should only be
undertaken with the correct safety equipment.
• Do NOT attempt to install this product if it is not safe to do so.
• It is recommended that appropriate cut resistant gloves and safety
glasses be worn whilst handling these products and during
installation.
• WARNING:Beforecommencingtheinstallationalwayscheckroongand
other building material for the presence of asbestos prior to cutting. If
asbestos is present or the type of material is unable to be determined, do
not proceed with the installation and seek expert advice.

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
Positiontheashingin
the desired location so
that the tiles that need to
be cut or removed can be
determined. Ensure bot-
tomedgeoftheashing
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.

Installation - Tiled Roof
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.
Foldingthecutsarkingapsbackonthemselvesresultsina
gutter arrangement that helps to prevent any water running down
the sarking from entering through the opening.

STEP 5
Lift the higher row of
tiles and using a piece of
timber or similar to wedge
to the tiles in the up
position.
Returntheashingtothe
roof and place as per the
initial markings made in
step 2.
STEP 6
Using a soft hammer, form
theashingtoconformwith
thetileprole.
Position the varipitch
temporarilyontoashing
andmakeanynal
adjustments. Turn the
bottomedgeoftheashing
over the lower tiles. Form
the bottom edge of the
ashingsothatthehigher
tiles can be replaced with
minimal gaps. Remove the
varipitch for next steps.
Take care to avoid unnecessary movement of the top row of
tiles. Excessive movement of these tiles may damage the
ridge tile pointing.
Foradditionalweatherproong,turnthetopedgeoftheashing
upwards so that it seals against the tile above.

STEP 7
Lift or remove the formed
ashing.
Using a weather resistant
roongsiliconesealant,
apply a 15-20mm wide
bead of sealant around
the perimeter of the
ashingarea.
Returntheashingtothe
tiles ensuring no gaps
greater than 3mm are
present. Seal any gaps
along the front or side
with additional sealant.
STEP 8
Return the higher row of
tilestotheashing.
These should have been
cut to provide a snug
twhichstillallowsthe
throat of the ventilator to
tontotheashing.
Adjusttheashingtoget
agoodt.

Check the varipitch level
again and ensure it is still
level across all directions.
Screw the varipitch to the
ashingwiththethree
screws provided at the
pre-drilled holes on the
varipitch.
Lock the varipitch by
screwingthexingclipinto
the lower half with one of
the screws provided.
Ensure the top of the varipitch is horizontal relative to both the
lateral axis across the roof and the longitudinal axis in-line with
the roof pitch.

STEP 1
Select a suitable position for
the ventilator.
Slip the top edge of the
ashingundertheridgecap
and mark position.
The vents must be installed
to the ridge cap. Any other
installation requires a
licensed plumber.
STEP 2
Removetheashingand
cut a square or round
opening around the
centre of the position
marks.
Turn up the corrugations
or pans on both the low
and high sides. This will
help to prevent water
ingress.
Ensurethattheashingcoverstheroofcorrugationsorribs
equally and that it is located between roof rafters.

it over the cutout.
Ensure that the top of
theashingisslipped
under the ridge capping.
For lower pitched roofs,
turn up the top edge
oftheashingbefore
slipping under ridge
capping. This will help
prevent water ingress.
