The Rinnai R229230NPP condensing 90° elbow is designed to work with Rinnai Sensei™ series condensing tankless water heaters — including models RU199i, RU180i, RU130i and RUR160i. This concentric vent accessory handles a 2″ internal exhaust and 4″ outer air intake (2/4″) configuration and facilitates safe, efficient venting of condensate return systems.
Manufactured from polypropylene (PPs) for the inner exhaust section and plastic for the outer intake, the elbow is lightweight but engineered for durability. It supports high-efficiency installations by enabling compact vent runs and tighter clearances, helping streamline installation and reduce material cost.
Ideal for contractors and homeowners upgrading or installing Rinnai condensing tankless systems, this 90° elbow supports professional performance and compatibility. Because proper vent termination is critical for performance and code compliance, this part ensures the right fit and transition. Consider adding the R229230NPP to your venting kit to complete your installation.
