Water Commercial Gas Common Venting Tankless Water Heaters Common Venting For Rheem Commercial Tankless Natural Gas Water Heaters Overview Rheem offers a manufacturer tested and UL/ULC listed common venting system providing longer lengths and fewer wall penetrations than single-unit venting. The system is polypropylene stabilized (PPs) material and Intertek certified for UL - and ULC-S and manufactured by CentroTherm EcoSystems in the USA. Venting pieces are self-locking and sealing and can be pushed together without the use of cement or glue. The common vent system is CSA certified (ANI Z.0., Gas Water Heaters Standards) for use with up to 0 units of the following Rheem high efficiency, natural gas tankless water heaters; RTGH-C9DVLN and RTGH-CM9DVLN.
