The Ventis Class-A 304L All Fuel Chimney System is a premium-grade venting solution engineered for superior safety, efficiency, and durability in all-fuel applications. Every component in the Ventis system is precision-manufactured to meet strict UL103HT and ULC S629 standards, ensuring safe operation even under the extreme temperatures of wood-burning, coal, oil, or gas appliances. At the heart of this system is its dual-wall construction, featuring a 304L stainless-steel inner liner for exceptional resistance to corrosion and high heat, paired with a 430 stainless-steel outer wall for structural strength and long-term weather protection. The result is a system that maintains excellent draft performance while standing up to the harsh conditions of continuous fireplace, stove, or furnace use. Each section of Ventis Class-A chimney pipe is welded for airtight integrity, providing consistent performance with minimal heat loss and reduced creosote buildup. The air-insulated double-wall design allows for safe installation with only 2 inches of clearance to combustibles, offering flexibility in residential and commercial installations alike. What makes Ventis unique is its exclusive system compatibility — all components are designed to lock and seal together seamlessly. To maintain certification, safety, and performance ratings, Ventis chimney sections, elbows, tees, supports, and flashings must be used together as a unified system. Mixing components from other manufacturers may compromise safety or void compliance. Ideal for wood stoves, fireplaces, furnaces, and boilers, the Ventis Class-A 304L All Fuel Chimney is trusted by professional installers and homeowners alike for its reliability and precision-built quality. Whether you’re venting through a wall, ceiling, or roof, this system delivers outstanding results, meeting the highest standards for efficiency and fire safety.
