The 904L Mi-FLEX 150mm x 1m Flue Liner from National Flues is a double-skinned, flexible flue liner ideal for relining masonry chimneys. Crafted from 904L grade stainless steel, both the inner and outer layers boast a thickness of 0.105mm, ensuring durability and longevity. The smooth inner liner coupled with a convoluted outer skin not only meets but exceeds performance expectations.
This liner supports burning gas, oil, coal, coke, cured dry logs, cured dry peat, and approved smokeless fuels. Recognized by HETAS and CE approved, you can be assured of its quality and safety. Installation is straightforward: always fit from the top, ensure arrows point upwards (indicating the gas flow), and use a Nose Cone and string for smooth insertion.
Regular maintenance is essential, especially for chimneys serving solid fuel appliances, and sweeping at least once a year is recommended for optimal performance.
