Product Details

Rinnai Condensing Roof Term Extension Kit 2" x 4" 60/100 Polypropylene 185348NPP

The Rinnai 185348NPP is a 2" x 4" (60/100 mm) polypropylene (PPs) concentric roof termination extension kit designed for condensing gas boilers and tankless water heaters. This extension increases the overall height of a standard roof termination when additional clearance is required above the roofline. Its concentric design allows both exhaust and intake air to pass through a single roof penetration for a clean and efficient installation.

Key Features

  • Concentric Vent Design – Single integrated system for both exhaust and combustion air intake
  • 2" x 4" (60/100 mm) Configuration – 2-inch inner exhaust and 4-inch outer intake
  • Polypropylene Inner Exhaust – High heat resistance and corrosion resistance for condensing applications
  • Durable Outer Intake Pipe – Built for long-term exterior roof installations
  • Roof Termination Extension – Adds approximately 19.5 to 19.76 inches of vertical length
  • Ideal when standard termination height does not meet roof clearance requirements
  • Supports high-efficiency condensing boiler and tankless systems

Why Choose the Rinnai 185348NPP Extension Kit

This concentric roof termination extension kit provides a practical solution when additional vent height is required for safe and code-compliant installation. Its polypropylene exhaust core resists acidic condensate produced by high-efficiency systems, while the concentric design maintains a streamlined and professional rooftop appearance. It is engineered specifically for Rinnai condensing applications to ensure proper system performance.
