Navien Common Vent Collar Kit

The Navien Common Vent Collar Kit prevents back flow (back-draft) at the exhaust vent while the boiler unit operates.

By closing the exhaust vent as soon as the combustion cycle ends, the Navien Common Vent Collar Kit retains heat in the system for longer periods.  

When using a common vent in a cascade system, back ow devices are required to prevent exhaust from entering the building.

Required for Cascade/common vent installations with NPE-2, NFC-H, NFB-H, NHB-H, and NHB (NHB -110 & NHB-150 models) series units produced on or after September 15, 2016.

Includes Cascade Cable (GXXX000546), VID jumper cable and common vent collar damper.
