Product Details

Rinnai Common Vent Elbow 3" 45 Degrees Set Of 2 For Tankless Water Heaters 790120

The Rinnai 790120 is a 3-inch, 45-degree vent elbow set designed for use in tankless water heater venting systems. This accessory includes two precision-formed elbows that allow installers to efficiently navigate venting paths in both residential and commercial indoor installations.

Designed specifically for Rinnai RL and LS series tankless water heaters, these elbows are commonly used in separate intake and exhaust venting configurations as well as common vent systems. The 45-degree angle allows for smoother directional changes in vent piping while maintaining proper airflow and system performance.

Constructed from high-quality polypropylene (PPs), the vent elbows are corrosion-resistant and engineered to handle the condensate and exhaust conditions typical of high-efficiency condensing tankless water heaters. The lightweight design simplifies installation while maintaining the durability required for long-term performance.

For added installation flexibility and safety, the Rinnai 790120 elbows are approved for zero clearance to combustible materials, making them suitable for tight mechanical spaces and professional HVAC installations.
