Installations in the U.S. require exhaust vent pipe that is a combination of PVC & CPVC complying with ANSI/ASTM D1785 F441, polypropylene pipe that complies with ULC S636, or stainless steel complying with UL1738. Installations in Canada require exhaust vent pipe that is certified to ULC S636.
Intake (air) pipe may be ABS, PVC, CPVC or galvanized material.
Installer must comply fully with manufacturer’s installation instructions, including use of minimum exhaust length CPVC, to maintain ANSI Z21.13 safety certification.
Closet and alcove installations do not allow the use of PVC under any circumstances
* To calculate max equivalent length, measure the linear feet of the pipe, and add 5 feet (1.5m) for each elbow used.
** Allowed only if the vent pipe is no more than 20 equivalent feet longer than the air pipe.
