DuraVent DVL 6 Inch Double Wall Steel Stove Pip
This model provides a clean two-piece connection from the stove to the ceiling support box or finishing collar, delivering a seamless, professional look. The DVL line features adjustable lengths from 40 to 68 inches, eliminating the need to cut or crimp pipe ends for a precise fit. It is designed to safely vent multiple fuel types—wood, oil, coal, or gas—helping maintain indoor air quality and system safety during operation.
DuraVent DVL Double-Wall Chimney Stove Pipe, 6″ x 48″
This double-wall pipe is engineered to maintain high flue gas temperatures for a robust draft, enhancing overall stove performance. It efficiently channels smoke and exhaust from varied fuel sources—wood, oil, coal, and gas—outside the home, contributing to safer, more comfortable indoor air. The design emphasizes ease of installation and reliable, long-term venting.
Selkirk 6″ Telescopic Stove Pipe
This telescoping pipe offers a flexible connection from a wood-burning appliance to a chimney system. It extends from 38 to 68 inches, reducing the need for cutting while accommodating varied ceiling heights and installation layouts. The robust double-wall construction helps preserve heat and maintain a steady draft during operation.
AllFuel HST 6″ x 48″ 304 Stainless Steel
A Class-A double-wall chimney pipe designed for AllFuel HST systems. It uses 304 stainless steel with laser-welded seams for corrosion resistance and is insulated with a ceramic fiber blanket, offering a two-inch clearance to combustibles while maintaining high internal temperatures for proper draft. Compatibility is specific to AllFuel HST Class-A systems, ensuring a secure, efficient venting solution.
AllFuel HST 6″ x 36″ Stainless Steel
This shorter AllFuel HST segment shares the same Class-A stainless design and insulation advantages as the 48-inch version, suitable for tighter installations. It should be used within AllFuel HST Class-A systems and provides reliable performance with strong corrosion resistance and efficient drafting capabilities.
Buying Guide
- Material and insulation: Double-wall pipes typically use galvanized steel or stainless steel with ceramic fiber insulation. Stainless options offer superior corrosion resistance, especially in humid environments or with certain fuels. Thicker insulation improves heat retention and reduces creosote formation.
- Compatibility: Check that the pipe matches your stove, chimney system, and Class-A requirements. Some AllFuel HST pipes are designed specifically for their Class-A systems and may not work with other brands.
- Length and adjustability: Telescoping and adjustable lengths simplify installation by reducing the need for cutting. Ensure the available range covers your ceiling height and any offsets in your layout.
- Seam quality and fittings: Die-formed fittings and laser-welded seams provide stronger joints and reduce leak points. Look for 2-piece connector designs for clean, easy installations from stove to ceiling.
- Fuel compatibility: Some pipes are optimized for wood, oil, coal, or gas, or for multiple fuels. Confirm the intended use matches your heating sources to maintain safety and performance.
- Ventilation performance: A pipe that maintains high flue gas temperatures supports a stable draft and reduces creosote buildup. This is particularly important for wood stoves and small spaces.
- Safety clearances: Ensure insulation and construction meet local clearances to combustibles. Adhere to manufacturer recommendations for minimum clearances around the pipe.
- Installation ease: Two-piece finishing pipes, quick-connect fittings, and adjustable systems minimize complex fabrication and reduce installation errors.
- Maintenance considerations: Periodic inspection of seams, insulation, and any joints helps preserve performance and safety over time.
When selecting a double-lined chimney pipe, prioritize a complete system that matches your stove output, chimney type, and ceiling height. A well-chosen pipe improves draft, reduces heat loss, and supports safer, longer-lasting wood-burning performance.
