Boiler Venting & Accessories

Venting solutions and other accessories for the Rinnai Condensing Wall-Mounted Gas Boilers ensure a simple installation in any home, and are ready for direct-vent right out of the box—through either a wall or roof penetration.

Concentric Venting

Allows intake air and exhaust gas to flow through one pipe, requiring only one penetration through the wall or roof.  The snap-fit connections eliminate the wait time of setting and curing, making installations quicker.  A secure seal endures expansion and contraction from temperature fluctuations, which mitigates the risk of stress fractures over time.

  • Rinnai also offers a 2” X 4” diameter concentric venting solution for I-Series condensing boilers. This smaller solution uses less material and significantly reduces expense.

2" PVC, CPVC, or PP

Available for use with Rinnai I-Series boilers, this solution provides a simple and affordable option for long vent runs.
