Description
The Noritz ETHF021 Exhaust Flue directs combustion gases away from compatible heating equipment during operation to support proper venting and controlled exhaust flow. Designed without the ring and gasket components, this exhaust section connects to the venting pathway of tankless water heating assemblies where it assists with routing flue gases safely through the system. Its configuration supports balanced airflow movement, stable combustion discharge, and maintained operating conditions during heating cycles. Commonly utilized in water heating and HVAC systems, this flue assembly contributes to efficient exhaust management and consistent ventilation performance during continuous equipment operation.
