The AllFuel HST Pellet Vent 3" Diameter x 12" Long Pipe Length is designed to safely vent pellet stoves, corn stoves, and other approved biofuel-burning appliances. It connects to other 3" AllFuel HST Pellet Vent components using the positive twist-lock connection, creating a secure, leak-resistant joint without the need for screws or fasteners.
The positive twist-lock connection provides a fast, secure fit without the need for screws or fasteners. Its dual-seal connection combines a metal-to-metal seal with an encapsulated O-ring gasket, eliminating the need for silicone during installation.
Note: Some stove manufacturers require silicone sealant despite the internal gasket. Always check your appliance manual for assembly instructions.
Note: This pipe has an overall length of 12 inches and an installed (effective) length of approximately 10½ inches, as 1½ inches is lost inside the overlapping twist-lock connection.
Built for durability, the AFPV3-12 features a .019" thick TIG welded 444 stainless steel inner wall that resists corrosion from pellet, corn, and biofuel exhaust, along with a .019" laser welded Galvalume outer wall for added strength and protection against the elements. Backed by the AllFuel HST Limited Lifetime Warranty, this pipe is built to provide years of dependable performance.
