Installation - Tiled Roof
STEP 4
If the roof is sarked, cut
sarking in a cross and fold
back onto itself to give a
300
mm
opening.
Tape the corners to the
surrounding sarking with
foil tape to prevent them
fouling the ventilator.
Folding the cut sarking flaps back on themselves results in a
gutter arangement that helps to prevent any water running down
the sarking from entering through the opening
STEP 5
Fit the ventilator into
place and ensure
surrounding tiles are
fitted securely.
For BAL compliance, no gaps greater than 2mm may be
present. A water tight install can be achieved by carefully
forming the flashing to the tile profiles, without the use of
sealant.
