Product Details

Rinnai Vent Adapter 2" x 4" Condensing Horizontal Starter 229253NPP

The Rinnai 229253NPP is a 2/4-inch (60/100 mm) condensing horizontal venting starter adapter designed to initiate a horizontal vent run for a single high-efficiency condensing tankless water heater or boiler. Its concentric "pipe-within-a-pipe" design allows for both exhaust and intake air through a single wall penetration, providing a professional and sealed combustion setup.

Key Features

  • Concentric Design – 2-inch inner exhaust and 4-inch outer air intake for single-penetration venting
  • Material – Inner exhaust made of high-quality polypropylene (PPs) for corrosion resistance and durability
  • Safety Standards – ULC-S636 compliant for Canada and meets Category IV gas appliance venting requirements
  • Single-Unit Installation – Not intended for common venting systems
  • Snap-Fit Connection – Requires no glues or solvents, allowing immediate use after installation

Compatible Units

  • Rinnai SENSEI™ Series (RU199i, RU180i, RU160i, RUR199i)
  • Rinnai CU Series Commercial Condensing Tankless Water Heaters
