CPVC (CHLORINATED POLYVINYL CHLORIDE)

System 636 CPVC carries a ULC S636 Class IIB certification and is certified for use up to and including 90°C (194ºF). Ensure the proper System 636 CPVC Cement and Primer is to be used for installation.

 

MATERIAL IDENTIFICATION

Material type and/or temperature rating is included in the pipe print line as well as on the mandatory orange and black warning label applied to each fitting. All certified IPEX System 636 products carry a Warnock Hersey mark. Warning labels on pipe and fittings are required by ULC S636 and clearly distinguish a certified gas venting system from every day, non-certified plumbing pipe. Look for the orange and black label and the mark of a recognized certification agency as assurance the system being used is certified.

 

SPECIAL NOTES

System 636 Pipe, Fittings and Cements are certified as a system and must be installed as such. Different manufacturers have different materials, joining systems and adhesives. Do NOT mix pipe, fittings, solvents, or joining methods from different BH Vent manufacturers, this can result in unsafe conditions. Exchanging components from various manufacturers violates the conditions of certification in the ULC S636 standard and would void the IPEX product warranty. IPEX ABS plumbing pipe and fittings do not meet ULC S636 requirements and must not be installed for flue gas venting. When retrofitting existing water heaters, furnaces or boilers, do not connect System 636 certified vent systems to existing, non-certified appliance vent materials. Replace the entire venting system with listed product to ensure compliance. Before connecting any piping system to an appliance, ensure the manufacturers’ installation instructions are followed, especially with respect to vent material selection.
