Ubbink Polypropylene Concentric Venting System for Rinnai Condensing Water Heaters

Upgrade your Rinnai condensing water heater installation with the Ubbink Polypropylene Concentric Venting System—a smarter choice designed for safety, efficiency, and ease of use. This innovative system simplifies ventilation while offering superior durability compared to traditional PVC solutions.

Engineered for Modern Installations
The slim 4-inch concentric design reduces roof or wall penetration needs to just one hole, saving space and streamlining installation. Its pre-angled exhaust ensures condensate drains efficiently without backups, minimizing maintenance hassles. Crafted from corrosion-resistant polypropylene (PPs), this vent resists stress fractures and requires no toxic solvents—making it safer for installers and recyclable for eco-conscious users.

Built for Rinnai Tankless Efficiency
Perfectly matched for Rinnai’s RU199i, RU160i, CU199i series, and other condensing models, this system meets strict ULC-S636 standards for Canadian installations. The dual-vent structure combines an outer air intake (4 inches) with an inner exhaust (2 inches), delivering balanced airflow while maintaining a sleek professional finish.

Save Time and Costs
Unlike PVC systems that demand curing time before use, this vent lets you activate your water heater immediately post-installation. Over time, its durability reduces replacement costs while its lightweight design cuts labor hours—making it a cost-effective long-term solution.

Whether you’re a contractor prioritizing efficiency or a homeowner seeking reliable performance, this venting system delivers unmatched value with its blend of safety, sustainability, and simplified installation流程。
