The Navien 30014367A Common Vent Collar Kit & Damper/Backflow Preventer stops exhaust gas backflow (back-draft) at the exhaust vent during operation of the water heater or boiler. By closing the exhaust vent as soon as the combustion cycle ends, the Navien backflow damper retains heat in the system for longer periods. This improves the system's thermal efficiency.

When using a common vent in a cascade system, backflow devices such as this item are required to prevent exhaust from entering the building. This item is a required accessory for cascading and common venting of up to 8 cascaded systems.

For use with all of the NPE tankless water heaters and NHB boilers made after 9/14/2016:
