The AllFuel HST Pellet Vent 3" Round Vertical Termination Cap is designed to provide a safe, weather-resistant termination for 3" AllFuel HST Pellet Vent systems. Installed at the top of a vertical vent run, it helps prevent rain, debris, and animals from entering the vent while allowing exhaust gases to vent freely for safe, efficient appliance operation.
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: The AFPV3-RVTC is designed for vertical vent terminations only. Always follow your appliance manufacturer's installation instructions and local building codes for proper vent termination height and location.
Built for durability, the AFPV3-RVTC 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 termination cap is built to provide years of dependable performance.
