IPEX System 1738 Flue Gas Venting



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. 

The safety concern today is in the use of plumbing Solid Wall Schedule 40 or Foam Core DWV pipe and fittings in FGV applications. These products were never intended to be used in FGV applications, but they have been chosen because they are often the least expensive materials available. 

Some manufacturers of these products have stated repeatedly that these products are not designed for FGV. These products do not meet the key performance requirements nor most of the material requirements of UL 1738. Simply put, plumbing DWV products are NOT designed to meet the life safety standards of FGV applications. 

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.

System 1738 Flue Gas Venting is a complete and fully certified system designed exclusively for the purpose of venting Categories II and IV gas burning appliances. The use of Schedule 40 Solid Wall or Foam Core Plumbing DWV pipe and fittings do NOT meet the UL 1738 safety standard for venting carbon monoxide, an extremely dangerous and silent killer.
