The use of plastic venting systems on gas fired water heaters, furnaces and boilers has undergone a significant change. The NFPA 54-18 and IFGC-18 Fuel Gas Codes now recognize the UL 1738 venting standard across the United States. There is a safety concern for Foam Core DWV pipe and fittings in FGV applications. Product failures have prompted the appliance manufacturers to remove cell core PVC from the appliance standards. Solid wall PVC is still permitted but were never intended to be used in FGV applications but are often chosen because they are inexpensive.


First-of-its kind, System 1738® is a system fully certified to UL 1738, consisting of pipe, fittings, termination kits, and cement manufactured to strict quality, performance, and dimensional standards.


Our PVC flue pipe is rated for a maximum flue gas temperature of 149°F and is fully certified to the rigorous requirements of UL 1738 vent pipe standard for gas-burning appliances, Categories II and IV.
