System 1738 Flue Gas Venting offers a full range of pipe, fittings and termination components that are manufactured from an engineered PVC compound, rated for a maximum flue gas temperature of 149?F and that are fully certified to the rigorous requirements of UL 1738 venting standard for gas-burning appliances, Categories II and IV.
System 1738 pipes and fittings are black in color which protects against UV degradation. Material type, application and temperature rating is included in the pipe print line as well as on the orange and black labels applied to each fitting. All System 1738 products have been certified by Intertek and carry an ETL mark as proof of certification. Markings on pipe and fittings are required by UL 1738 and clearly distinguish a certified gas venting system from every day, non-certified plumbing pipe and fittings. Look for the System 1738 label and the mark of a recognized certification agency as assurance that the venting system being used is certified.
