316 Flue Liner

This 316 flue liner is a flexible twin-wall chimney liner designed for relining suitable existing masonry chimneys. Made with corrosion-resistant 316L stainless steel on both the inner and outer skins, it provides a dependable lining solution for wood-burning stoves, multi-fuel stoves and open fires using suitable fuels. The corrugated outer skin helps improve crush resistance during fitting, while the smooth inner skin supports efficient flue gas flow, improved condensate drainage and easier sweeping over time. This makes the liner a practical choice for homeowners and installers who need a flexible chimney liner that is easier to fit, use and maintain.

This 316 flexible flue liner is suitable for seasoned wood and compatible with multi-fuel appliances installed into appropriate masonry chimneys. It is not suitable for smokeless fuel. For more demanding use, including harsher operating conditions or slumbering, a 904 flue liner may be the better choice. A nose cone is included with the fitting kit to help guide the liner through the chimney during installation. This can make fitting smoother and more efficient, especially when working with existing chimney bends.

Correct installation is essential for safe and reliable flue performance. Always ensure your flue liner is fitted, checked and approved by a competent professional before use.
