info@ventair.com.au | www.manrose.com.au
Cut pliable sleeve where indicated on the sleeve for the relevant pipe size: 150/160mm
Slide flashing down over pipe. Water can be used as a lubricant
You can now proceed to the actual roof installation.
Cut a neat hole in roofing sheet with minimum clearance for pipe and insert pipe through hole.
Apply a neutral cure silicon sealant on underside of flange.
Turning back flexible flange makes this simple.
Press pipe flashing into contours of roof panel configuration.
Fasten using the screws supplied (Hex/slot head - 10pcs).
Drill a 5mm clearance hole in the flange for each screw.
The screws can be driven into the roof without the need for a pilot drill hole, or use a 2.5mm drill.
Fit fasteners progressively outward in opposing pairs to avoid gaps.
Do not use unapproved fasteners-check roofing manufacturer recommendations.
Screws supplied are: AS3566.1 1990 Class 3
In certain applications it may be advantageous to install the flashing on the "Diamond" or bias.
This particular method of installation is especially suitable when having to seal enlarged holes, for
penetrations on steep pitched roofs.
Specifications are subject to change without notice
Do not use old model FAN2444 (with resistor) or FAN0372 fan timers
