The 904L Mi-FLEX 200mm x 30m COIL is the ultimate solution for relining masonry chimneys. Constructed from premium 904L grade stainless steel, this double-skinned flexible flue liner guarantees longevity and resilience. The smooth inner lining and convoluted outer skin, both 0.105mm thick, are expertly designed to withstand the rigours of burning gas, oil, coal, coke, cured dry logs, cured dry peat, and approved smokeless fuels.
It features an innovative quattrolock seal, achieved by bending a single strip of steel at 180 degrees and folding it in four planes. Approved and listed by HETAS and CE, this flue liner embodies top-tier safety and quality standards. Installation is straightforward but does require careful preparation, including ensuring chimney suitability, sweeping, and securing pot condition.
Maintenance is crucial; for solid fuel appliances, annual chimney sweeps are recommended.
