Venting & Accessories
Rinnai offers the most flexible set of venting options and other accessories in the industry, enabling easier installation for you, and making it possible for customers to have a better array of options for any building configuration.
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.
- This solution is available in 3" X 5" diameter for HE and HE+ models.
- Rinnai also offers a 2" X 4" diameter concentric venting solution for SE and SE+ models and I-Series condensing boilers. This smaller solution uses less material and significantly reduces expense.
2" PVC, CPVC, or PP
Available for use with Rinnai SE and SE+ tankless water heaters and I-Series boilers, this provides a simple and affordable option for long vent runs.
