roof Installation
(Recommended duct length: 3 metre)
Mount the 100mm rigid PVC pipe securely to the beams, trusses or other appropriate structures, refer
figure 1.
the pipe should be mounted either vertical or perpendicular to the roof cladding with the roof
penetration being sealed using a dektite or other sealing device.
ensure that the pipe protrudes a minimum of 80mm past the top of the Dektite, checking that the
mounting flange clears the roof cladding at upper edge as shown in figure 1 — Roof Mount Option.
Maximum recommended protrusion is 400mm. Fit mounting flange, refer figure 2, to pipe using silicon
sealant, then tape in position until sealant has set.
Pass power cord and plug through mounting flange and pipe, then out the slotted end of the PVC
pipe for connection to the female plug coming from the canopy/rangehood or authorised switching
mechanism in bathroom application, refer figure 2.
Fit fan module to mounting flange by placing in position, rotating clockwise to engage bayonet fingers
then secure by screwing in locking screw (while holding fan module firmly in the fully clockwise position),
refer figure 2.
