gasket) of the elbow or straight section of pipe for running the exhaust or intake pipe from the water heater.
Steel joint Locking Bands (available from DuraVent supplier) must be used at each pipe joint. The connector rings ensure
that the joints do not separate under heavy loads. These connector rings must be used to comply with ULC-S636
requirements. See following photo with the joint connector attached to the pipe sections.

end of the elbow or straight section into the PVC adapter. Use a twisting motion while pushing the male end of the pipe
or elbow into the PVC adapter to fully seat into the gasket. The male end of the pipe or elbow must always point toward
the water heater.
Secure Locking Band to connection joint by sliding the hook over the lip of the joint as shown below.
