Rinnai 224052 Concentric Vent Pipe Extension, 19-1/2 in., Non-Condensing

The Rinnai 224052 is a 19-1/2 in. concentric vent pipe extension for indoor non-condensing Rinnai tankless water heaters, part of the Ubbink venting system with a plastic intake shell around an aluminum exhaust liner.

The white semi-gloss plastic outer pipe is dent resistant, corrosion-proof and rated non-flammable to UL94-V0, while the thick-walled seamless aluminum inner pipe carries exhaust. Both cut more easily than stainless steel, so the piece can be trimmed to length on site. It works with every indoor Rinnai water heater except the 98 series, which uses separate intake and exhaust pipes.

Seal rings handle up to 400F, the pipe may run with zero distance to combustible materials, and the part is GSA approved. An elbow may be needed depending on the vent route, and professional installation is recommended.
