IPEX Concentric Vent Kit Assembly (System 636):
1. Once the proper location has been determined, cut a
hole in the roof or wall large enough to
accommodate the outer pipe. The size of the hole can
vary greatly depending on the roof pitch.
2. As per the procedures outlined, solvent cement the
inner pipe to the concentric Wye fitting.
3. Solvent cement the outer pipe to the concentric Wye
fitting.
4. Slide the assembly through the roof or wall
penetration. (Install flashing as required)
5. To permanently affix the rain cap, it should be
solvent cemented to the inner pipe. For installations
where removal of the cap may be required for service
or cleaning the cap, it can be fastened mechanically
(see instructions). For either installation method, the
outer pipe is only a friction fit with the cap.
