Duravent 3PVL-X6R Chimney Adapter Pipe Pellet Vent

Product Description

The DURAVENT 3PVL-X6R is a chimney adapter pipe that connects a 3-inch pellet vent system to a 6-inch DuraPlus chimney support box. This transition fitting is used in vertical pellet venting applications where a pellet appliance vents upward through a Class A chimney enclosure. The adapter serves as the critical interface between the smaller-diameter pellet vent pipe and the larger chimney kit assembly. Installation is performed by HVAC technicians and chimney installation crews working on residential or light commercial solid-fuel heating setups. At 1.5 pounds, the fitting is lightweight and manageable during overhead or attic-space work.

This adapter is designed for vertical pellet venting configurations where the pellet vent pipe must transition into a 6-inch DuraPlus chimney kit. It is used in residential installations where a pellet stove or pellet insert routes exhaust vertically through an interior or exterior chase. The fitting attaches directly to the 6-inch chimney kit assembly, making it the starting point for the chimney enclosure portion of the vent system. It is sold individually as a single unit.

Installation Notes

Installation should be performed by a qualified HVAC technician or certified chimney professional in accordance with local building codes and the appliance manufacturer's venting requirements. Shut down and allow the pellet appliance to cool completely before beginning any vent or chimney work.
