Product Details

Rinnai Vent Adapter 2" x 4" Condensing Vertical Starter 227412NPP

The Rinnai 227412NPP is a 2-inch / 4-inch (60/100 mm) condensing vertical starter adapter designed to initiate a vertical (roof) vent run for a single high-efficiency tankless water heater or condensing boiler. This concentric vent component features a pipe-within-a-pipe design, allowing both exhaust discharge and combustion air intake through a single roof penetration for a clean, sealed installation.

Key Features

  • Concentric Vent Design – 2" inner exhaust pipe with 4" outer air intake for single-penetration vertical venting
  • Vertical Starter Adapter – Designed specifically for roof discharge applications
  • Durable Polypropylene (PPs) – Corrosion-resistant material ideal for acidic condensate from high-efficiency appliances
  • Single-Unit Installation – Not for common venting; intended for individual sealed combustion systems
  • Snap-Fit Connections – Gasketed joints require no glue or solvents for fast installation
  • Professional Alternative to PVC – Reduced risk of stress fractures and cleaner appearance

Why Choose the Rinnai 227412NPP Vertical Starter Adapter

This concentric vertical starter adapter provides a reliable and code-compliant solution for beginning a vertical vent system on Rinnai condensing tankless water heaters and boilers. Its polypropylene construction resists corrosion from condensate, while the snap-fit connection system ensures a secure, airtight seal without curing time. Ideal for professional residential and light commercial installations requiring sealed combustion through a single roof penetration.
