Listed and Warranted Plastic Gas Vents

Currently there are only a few manufacturers that actually warranty/sanction the use of their product in the flue gas arena. Also Polypropylene, known as PP or PPS, is being brought to the USA from Europe where it has been successfully installed for over 15 years – PPS is fully recyclable and does not harm the environment when manufactured. These are VERY quickly gaining recognition with Appliance manufacturers, local ities having jurisdictions, and owners.

To be clear, PVC/CPVC manufacturers NOT listed below do not warranty their plastics for use as a flue gas conduit.
