AllFuel HST 8” x 24” Stainless Chimney Pipe

The AllFuel HST 8″ x 24″ 304 Stainless Steel All-Fuel Class-A Double Wall Insulated Chimney Pipe delivers unmatched durability and efficiency for residential heating systems. Built with 304-grade stainless steel on both inner and outer walls, this chimney resists corrosion far better than galvanized steel or lower-grade 430 stainless alternatives, ensuring long-term performance and safety. The ceramic fiber insulation maintains a 2″ clearance from combustibles while preserving optimal internal flue temperatures for a strong, consistent draft—ideal for wood stoves, fireplaces, furnaces, boilers, and outdoor wood furnaces.

Designed for seamless installation, the Twist-Lock connections allow for quick assembly, while the included locking band secures a tight seal, preventing draft loss and debris entry. This chimney is UL103HT-certified and compatible exclusively with other AllFuel HST Class-A double-wall chimney pipes, ensuring a perfect fit for all-fuel applications—wood, gas, coal, or oil. Its robust construction and insulation make it a dependable choice for both indoor and outdoor heating setups.
