Roof Installation
Recommended duct length: 650 motor — 3 metres.
Mount 100mm rigid PVC pipe securely to beams, trusses or other appropriate structures: refer figure 1. The pipe
should be mounted vertically or perpendicular to the roof cladding with the roof penetration being sealed using a
Dektite or other appropriate sealing membrane or device.
Ensure that the PVC 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.
