Once in desired position, tighten off the flue brace bracket and use self-tap screws (supplied) to fix off
the Safety Vent AIR pipe. The 50mm gap between a combustible ceiling and the Safety Vent AIR pipe
can be covered using the 80mm steel ceiling ring flush to the ceiling with no airgap required. (FIG 3)
This can be secured using plaster screws (not supplied) or Hi-temp silicone.
Connec�ng VisionLINE AIR pipe
Once the flue brace bracket is secure and in place, you can now start to a�ach further lengths of pipe
to continue and penetrate the roof. VisionLINE safety vent AIR is a twist lock flue, sections should be
pushed together and then ensured they are twisted into the locked position in the clockwise direc�on.
VisionLINE safety vent AIR CANNOT be cut, if you require smaller sections, please contact your
distributor.
Safety Vent pipe does not require securing screws or rivets once twist locked together, however if
connec�ng mul�ple sec�ons together to drop into a cavity it can be secured in this way.
Roof Penetration
Once the safety vent AIR flue has passed though the roof, the op�onal roof stabiliser bracket can be
used for further bracing and support (FIG 4)
FIG 4
At the roof level, use appropriate flashing to weather seal the penetration. (Not supplied)
Continue the safety vent AIR pipe past the roof penetration until the height satisfies AS/NZS 2918
(Refer to FIG 1)
VisionLINE Safety Vent AIR pipe can run at a height of 3 meters past the highest flue bracing support
without the need for addi�onal bracing. Pipe running past this distance will require further support.
Once the termina�on height is achieved, the flue cap can be fi�ed off by twist locking into place.
