Product Details

Rinnai Condensing Vent Extension Pipe 2" x 4" 60/100 mm 229308NPP

The Rinnai 790138 is a 6-inch Room Air (RA) Common Vent Starter Kit constructed from durable polypropylene (PPs). This component is designed to initiate a shared exhaust manifold for multiple high-efficiency condensing tankless water heaters. It serves as the foundational piece that begins the 6-inch common vent system in room air configurations.

Key Features

  • Room Air (RA) Configuration – Draws combustion air from the surrounding mechanical room
  • Common Vent (CVent) Classified – Allows multiple units to share a single exhaust trunk
  • 6-Inch Diameter Manifold Starter – Initializes the shared exhaust system
  • Durable Polypropylene (PPs) – Corrosion-resistant and certified for acidic condensate
  • Snap-Fit Assembly – Self-locking, gasketed joints require no glue or solvents
  • Scalable Commercial Design – Supports up to 8 tankless units depending on vent length and BTU capacity
