Concentric Vent Kit Assembly, Installation and Support
1. Follow the concentric vent kit instructions to properly assemble the kit.
2. Follow the concentric vent kit instructions to locate and cut a hole in the roof or wall large enough to
accommodate the largest dimension of the kit. The size of the hole can vary greatly, depending on the roof pitch.
3. For the IPEX System 636 Concentric Vent Kit, following the procedures outlined in the System 636 Installation
Guide:
a. Use the solvent cement specified in the installation guide to connect the inner pipe to the concentric Wye
fitting, then connect the outer pipe to the concentric Wye fitting using the specified solvent cement.
b. Slide the assembly through the roof or wall penetration. (Install flashing if needed)
c. Kits must be securely fastened to structure, to ensure dimensions shown below are maintained.
d. Straps are field supplied. Use straps, clamps or equivalent that will not score or damage the pipe. Do not
constrain or clamp the vent system anywhere between the appliance and the vent termination point such that
it is unable to expand or contract as it heats and cools during operation.
e. The weight of the concentric kits must be supported by clamps/straps and not by the vent system it connects
to.
f. All penetrations must be sealed according to local building codes. Caulking for side wall terminations and
flashing for roof penetrations are typical. Use only PVC/CPVC compatible sealing material, contact IPEX for
a complete list
g. Attach the rain cap. To mechanically attach the rain cap to allow for removal and cleaning the cap, follow the
instructions located in the section titled
Mechanically Fastened Rain Cap
. The rain cap can also be
permanently attached to the inner pipe with the solvent cement specified in the Installation Guide. Whether
mechanically or permanently attached, the outer pipe is only a friction fit with the cap.
h. Once the rain cap is installed and the kit secured, the kit can be connected to the venting system
i. For multiple horizontal installations, keep Concentric Vent Kit gaps close (up to 4" apart) or over 24" apart.
