enquiry@manrose.co.nz | www.manrose.co.nz
Cut the large roof fl ashing sleeve where indicated on the sleeve for the relevant tube size: 240/255mm
Slide the roof fl ashing down over the tube. Water can be used as a lubricant.
Position the top end of the tube into the cowl.
The top edge should sit 20mm inside the cowl.
Drill through the three pilot holes and screw the cowl to the tube.
You can now proceed to the actual roof installation.
Cut a 280mm diameter hole in the roofi ng with minimal clearance for the tube.
Insert the tube through the hole.
Apply a neutral cure silicon sealant on the underside of the fl ange.
Turning the fl exible fl ange back makes this simple.
Press the roof fl ashing into the contours of the roof confi guration.
Fasten the roof fl ashing to the roof using the tek screws supplied.
Drill a 5mm clearance hole in the fl ange for each screw.
The screws can be driven into the roof without the need for a pilot drill hole.
Fit the screws progressively outward in opposing pairs to avoid gaps in the seal.
In certain applications it may be advantageous to install the fl ashing on the diamond or bias.
This particular installation method is especially suitable when having to seal enlarged holes, for penetrations
on steep pitched roofs.
