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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdapts 3-inch pellet vent pipe to a 6-inch DuraPlus chimney support box\u003c\/li\u003e\n  \u003cli\u003eDesigned for vertical pellet venting installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with 6-inch DuraPlus chimney kit components including 6DP-KBSC, 6DP-KTTW, and 6DP-KMFG\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 1.5 pounds for easier handling during installation\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit for direct replacement or new installation use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the 6-inch DuraPlus chimney kit, specifically designed for use with support box and kit models 6DP-KBSC, 6DP-KTTW, and 6DP-KMFG as part of a vertical pellet venting assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation 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.
