INSTALL AT YOUR OWN RISK
The installation of this product may be dangerous and includes working at
heights - appropriate safety precautions should be taken prior to commenc-
ing. Please be aware of the following before installing this product.
• Follow all State or Territory, Regulator or OH&S guidelines for working
at height (e.g. roof work), electrical, working in conned 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.
• Isolate power before installation.
• It is recommended that appropriate cut resistant gloves and safety
glasses be worn whilst handling these products and during
installation.
• Caution: The turbine head of this product can rotate without warning
(even during installation) – always keep body parts away from moving
components.
• WARNING: Before commencing the installation always check roong
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.
• WARNING: Refrain from using a grinder to cut the roof tiles to avoid
exposure to resipirable crystalline silica dust. Instead, opt for a hand
tile cutter. Refer to the CSR silica fact sheet for details : https://www.

updates/monier-silica-fact-sheet_0523.pdf

Warnings and Important Notices
PRODUCT COMPLIANCE:
Compliance of this product to BAL requirements relies upon correct instal-
lation. It is recommended that installation is undertaken by a competent
and licensed tradesperson to ensure that the product installation is in
accordance with this Guide. In particular, care should be taken when
forming the ashing to ensure that there are no gaps between the roong
material and the ashing greater than 2mm. Seal any gap less than 2mm
with weatherproong sealant for weatherproong purposes.
IMPORTANT
Do Not Modify This Product: Compliance with BAL requirements is only
achieved by the unmodied product as supplied.
MAINTENANCE
This product requires regular maintenance to maintain its performance
- check and clean the emberguard (mesh) regularly to remove built-up
residue.
PRODUCT SUITABILITY:
Always check product suitability and limitations of use prior to selection –
refer to the Product Technical Statement (PTS) available online.

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.
Installation higher than the third row of tiles down from the
ridge may damage the ridge tile pointing and is NOT recom-
mended.
STEP 2
Position the ashing in the de-
sired location so that the tiles
that need to be cut or removed
can be determined.
Ensure the bottom edge of the
ashing extends far enough be-
yond the lower tile edge to allow
it to be folded downward toward
the roof at a later stage.
Mark-out the position to either
remove and/or cut the required
tiles.
Ensure the ashing is positioned with the slots for the xing
strap located at 12 and 6 o’clock mark. This is crucial for x-
ing strap assembly (see Step 10).

Installation - Tiled Roof
STEP 3
Cut the tiles marked
earlier using a hand tile
cutter being careful not
to crack the tile.
Refrain from using a
grinder to cut the roof
tiles to avoid exposure
to resipirable crystalline
silica dust. Instead, opt
for a hand tile cutter.
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
top surface of surround-
ing sarking with a suitable
tape to prevent them foul-
ing the ventilator.
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.
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.

Installation - Tiled Roof
STEP 5
Lift the higher row of tiles
and use a piece of timber
or similar to wedge to the
tiles in the up position.
Return the ashing to the
roof and place it under
the upper row of tiles in
the previously marked
position (step 2).
STEP 6
Using a soft hammer, form
the ashing to conform with
the lower tile prole.
Position the varipitch
temporarily onto ashing and
make any nal adjustments to
the ashing position. 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. Ensure the ashing is positioned with the slot for the
xing strap located at 6 o’clock mark
SLOT
Care should be taken when forming the ashing so that the gaps
between the roong material and the ashing are less than 2mm.

Installation - Tiled Roof
STEP 7
Remove the formed
ashing.
From above the roof, take
the xing strap and securely
x it to the vertical face of
lower tile batten.
Screw (not supplied) the
xing strap to the batten,
this will secure the lower
part of the ashing in future
steps.
STEP 8
Gently bend the upper
part of the strap so that
it is facing down the roof
and is approximately the
height of the ashing above
the surrounding roof tiles.

Installation - Tiled Roof
STEP 10
Remove the screw from the
lower part of the ashing -
this screw should located
adjacent to a cut-out slot.
STEP 9
Install the cut portion of
the tile so that it is inline
with the lower edges of
the surrounding tiles.
Using a weatherproong
sealant, apply a 15-
20mm wide bead of
sealant around the
perimeter of the ashing
area.
Apply SealantApply Sealant
Ensure sufcient weatherproong sealant applied in tile troughs.
This helps prevent any water entering from adjacent tiles.
