Certified PVC/CPVC Vent Termination Options (continued)
3" and 4" Low Profile Vent Termination Kits
The following information should be used in conjunction
with the IPEX System 636 Installation Guide:

Termination kits are to be tested and certified for use
with the brand of pipe-fitting-cement system that is to
be utilized in the application. The IPEX Low Profile
termination is fully certified for use with IPEX product
only.

System 636 PVC Low Profile Vent kits are rated to 65°C
maximum and are made from certified compound.

All termination kits must be located and installed in
accordance with these instructions, local building code,
and CSA B149.1 Natural Gas and Propane Installation
Code.
Installation:
1. Once location is determined, cut 2 appropriately sized
holes in the wall to accommodate the pipe. (Reference
the Low Profile Termination Kit-Dimensions table
below)
2. Slide intake and exhaust pipes through the holes.
Secure (using solvent cement) both pipes to the base
of the vent termination kit. (Be sure to follow
guidelines for solvent cementing as described in the
System 696 Installation Guide)
3. Use the supplied screws and anchors to secure the
base to the wall. (a drilled 3/16" hole, 1-3/16" deep
will be needed for the anchors.) Use the base as a
template to locate the anchor hole.
4. Using the supplied screws, secure the Cap to the Base.
5. Upon securing the vent termination and pipes, seal the
wall penetrations (from the interior) using a PVC
compatible sealant material.
All exhaust vents and air inlets must terminate at the same
height to avoid severe personal injury, death, or substantial
property damage.
