These fittings are available from your Gas furnace Distributors for U.S. applications
only.
FOR MANUFACTURED MODULAR VENTING SYSTEMS

VENTING PIPES
BONDING OF PVC
Commercially available solvent cement for PVC must
be used to join PVC pipe fittings. Follow instructions on
container carefully for U.S. applications only. Canadian
applications require primer and cement that are from a
single system manufacturer.
For U.S. applications only:
Pipe and Fittings – ASTM D1785, D2466, D2661, &
D2665. PVC Primer and Solvent Cement – ASTM D2564.
Procedure for Cementing Joints Ref – ASTM D2855
1. Cut pipe square, remove ragged edges and burrs.
Chamfer end of pipe, then clean fitting socket and pipe
joint area of all dirt, grease, moisture or chips.
2.
After checking pipe and socket for proper fit, wipe
socket and pipe with cleaner-primer. Apply a liberal coat
of primer to inside surface of socket and outside of pipe.
DO NOT ALLOW PRIMER TO DRY BEFORE
APPLYING CEMENT.
3. Apply a thin coat of cement evenly in the socket.
Quickly apply a heavy coat of cement to the pipe end and
insert pipe into fitting with a slight twisting movement until
it bottoms out.
4.
Hold the pipe in the fitting for 30 seconds to prevent
tapered socket from pushing the pipe out of the fitting.
5.
Wipe all excess cement from the joint with a rag.
Allow 15 minutes before handling. Cure time varies
according to fit, temperature and humidity.
NOTE: Follow venting instructions carefully when
using PVC cement.
I
MPORTANT:
All joints must be water tight. Flue condensate is somewhat
acidic, and leaks can cause equipment damage.
I
MPORTANT:
Products installed in Canada must use vent systems that
are certified to the Standard for Type BH Gas Venting
Systems (ULC S636) for Class II-A venting systems (up
to 65°C). Components of the vent system must not be
interchanged with other vent systems or unlisted pipe
or fittings. Plastic components, specified primers, and
glues must be from a single system manufacturer and not
intermixed with other system manufacturer's vent system
parts.
