Requirements for installation in Canada
1. Installations must be made with a vent pipe system
certified to ULC-S636.
IPEX is an approved vent manufacturer in Canada
supplying vent material listed to ULC-S636.
2. The first three (3) feet of plastic vent pipe from the
appliance flue outlet must be readily accessible for visual
inspection.
3. The components of the certified vent system must not be
interchanged with other vent systems or unlisted
pipe/fittings. For concentric vent installations, the inner
vent tube must be replaced with field supplied certified
ventmaterial to comply with this requirement.

Installation & Operation Manual
Installing vent and air piping
Improper installation of PVC or CPVC
systems may result in injury or death.
ƽ CAUTION
Use only cleaners, primers, and solvents
that are approved for the materials which
are joined together.
NOTICE
1. Work from the boiler to vent or air termination. Do not
exceed the lengths given in this manual for the air or vent
piping.
2. Cut pipe to the required lengths and deburr the inside
and outside of the pipe ends.
3. Chamfer outside of each pipe end to ensure even cement
distribution when joining.
4. Clean all pipe ends and fittings using a clean dry rag.
(Moisture will retard curing and dirt or grease will
prevent adhesion.)
5. Dry fit vent or air piping to ensure proper fit up before
assembling any joint. The pipe should go a third to
two-thirds into the fitting to ensure proper sealing after
cement is applied.
6. Priming and Cementing:
a. Handle fittings and pipes carefully to prevent
contamination of surfaces.
b. Apply a liberal even coat of primer to the fitting
socket.
c. Apply a liberal even coat of primer to the pipe end to
approximately 1/2" beyond the socket depth.
d. Apply a second primer coat to the fitting socket.
e. While primer is still wet, apply an even coat of
approved cement to the pipe equal to the depth of
the fitting socket.
f. While primer is still wet, apply an even coat of
approved cement to the fitting socket.
g. Apply a second coat of cement to the pipe.
h. While the cement is still wet, insert the pipe into the
fitting, if possible twist the pipe a 1/4 turn as you insert
it. NOTE: If voids are present, sufficient cement was
not applied and joint could be defective.
i. Wipe excess cement from the joint removing ring or
beads as it will needlessly soften the pipe.
