7'' x 30' DuraFlex 304 Stainless Steel Chimney Liner

The DuraFlex 304 Stainless Steel Chimney Liner is a versatile and durable solution for a variety of heating appliances. Designed for use with pellet, non-condensing gas, wood burning, and oil appliances, this liner is the perfect choice for ensuring safe and efficient venting. With diameters ranging from 3" to 8" and lengths available in 15', 20', 25', 30', 35', and 50', it offers flexibility to fit various chimney sizes and requirements.

Key Features and Specifications

The DuraFlex 304 SS Chimney Liner is crafted from single-wall 304 stainless steel, known for its exceptional strength and resistance to corrosion. This material ensures a long-lasting and reliable performance, even in harsh weather conditions. The flexible design of the relining system is ideal for masonry chimneys, making it suitable for use with gas, wood pellet, oil, or wood appliances, including fireplace inserts, furnaces, boilers, and water heaters. The liner also provides superior protection against flue product condensation, which can damage masonry chimneys over time.

Practical Uses and Benefits

The DuraFlex SS relining system is not only designed to enhance the safety and efficiency of your heating appliances but also to meet strict industry standards. When used with the Simpson DuraVent Two-Ply Insulation Sleeve, the DuraFlex SS and 316Ti SS liners can be used for relining wood burning fireplace inserts and stoves, meeting UL 1777 and ULC S635 standards with 0" clearance to masonry. This ensures compliance with safety regulations while providing a seamless and secure installation. Additionally, the inclusion of installation instructions and a California Proposition 65 warning symbol demonstrates the manufacturer's commitment to safety and transparency.
