The 904L Mi-FLEX 100mm x 44m COIL is a double-skinned flexible flue liner specifically designed for relining masonry chimneys. Crafted from high-grade 904L stainless steel, this liner boasts a smooth inner surface and a convoluted outer skin, each with a thickness of 0.105mm. The unique construction, featuring a single strip of steel bent at 180 degrees and closely sealed with a quattrolock seam, ensures maximum durability and safety.
Approved by HETAS and CE certified, this flue liner is ideal for use with gas, oil, coal, coke, cured dry logs, peat, and smokeless fuels. Installation is a breeze: simply feed the liner down your chimney from the top, ensuring the arrows indicate the direction of gas flow. Regular maintenance is essential, with an annual sweep recommended for chimneys servicing solid fuel appliances to maintain optimal performance.
