Description

The Navien Common Vent Collar Kit prevents back ow (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.

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