Mount the 100mm rigid PVC pipe securely to the beams, trusses or other appropriate structures, refer

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 ange clears the roof cladding at upper edge as shown in gure 1 — Roof Mount Option.
Maximum recommended protrusion is 400mm. Fit mounting ange, refer gure 2, to pipe using silicon
sealant, then tape in position until sealant has set.
Pass power cord and plug through mounting ange 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 gure 2.
