Installation instructions for pipe fashing on fat tile or slate roof
A specially designed sloped roof fashing is available for sealing the insulated solar pipe, providing a watertight seal. This f ashing will seal a 1/2" pipe, it can also be modified to 3" by tearing of the inner sealing ring.
Determine the position of the pipe location, ensuring that the hole is clear of the rafters and battens. Drill a pilot hole in the position shown in the picture (f g. 33)
Bore a hole with a core bit of approximately 65mm to provide clearance for the insulated pipe (f g. 34)
On slate roofs there may be copper retaining pins installed. Remove the pin which is located immediately above the hole as shown (f g. 35)
Pre f t the roof fashing and measure the distance which protrudes below the slate lip, then cut of the excess as shown(f g. 36)
If required install some copper pins on the upper corners and on the center bottom, liberally apply the mastic (which is provided with the roof bracket kit) onto the area of slate which will be covered (f g. 37)
Drill a small hole for the pin on the bottom center of the fashing, then slide the fashing upwards and under the slate located above the 65mm hole. Push down firmly and bend the copper pins over. Extra mastic may be applied around the fashing for a watertight seal (f g. 38)
Installation instructions for 2 in 1 piping
It will be necessary to drill a larger hole in the slate.(f g. 39)
The hole in the f ashing can be enlarged by tearing of the inner ring of rubber. (f g. 40)
Push the piping through the f ashing and ensure that there is enough to reach the furthest away connection, then notch the insulation and cut the pipe closest to the panel connection. (f g. 41)
Install the fittings and secure the pipe along the top of the mounting brackets. Cover the fttings with high temperature adhesive tape. (f g. 42)
Secure the pipe internally to the roof battens so there is no movement in the pipe.Expanding foam can be applied inside the fashing; this will also provide rigidity and a good seal.Installation instructions for pipe fashing on corrugated / profiled roof
A specially designed sloped roof f ashing is available for sealing the insulated solar pipe, providing a watertight seal. The base of these fashings has a soft aluminium base molded onto an EPDM rubber grommet, which can be cut for pipe sizes from 1/4 "to 4" in diameter.
Installation instructions for 2 in 1 piping
Determine the position of the pipe location, ensuring that the hole is clear of the rafters and battens. Drill a 65mm (approx.) hole in the position shown in the picture (f g. 43)
The flexible base can be shaped to match the profile shape. Liberally apply the mastic on the base and f t the top part under the upper tile (if applicable). Screws or rivets can be used to secure the f ashing while the mastic is curing, see (f g. 44)
