Concentric Vent Kit for Condensing Tankless Heaters

Installers needing a single 8 in concentric

This kit suits professionals finishing vent runs on compatible Rheem condensing tankless units. It is not for installers working with non-condensing appliances or different vent diameters. Buyers who need a different connection size or material should look at other options. The product carries a California Proposition 65 notice.

Behaviour under continuous venting duty

The PVC construction handles steady exhaust temperatures from condensing operation without deformation. Horizontal and vertical orientations both maintain consistent airflow paths during prolonged use. The 3 in vent connection size supports the required flow rates for the intended appliance category. No electrical components are present to degrade over time.
