The 904L Mi-FLEX 300mm x 1m CUT LENGTH is a robust, double-skinned flexible flue liner seamlessly designed for relining masonry chimneys. Ideal for multi-fuel use, this liner works perfectly with burning gas, oil, coal, coke, cured dry logs, cured dry peat, and approved smokeless fuels. Constructed from premium 904L grade stainless steel, both the smooth inner and convoluted outer layers are 0.105mm thick. The flue liner's quattrolock seam ensures an unrivaled seal, achieved by folding a single strip of steel at 180 degrees and then folding it four ways. Rigorous HETAS and CE approvals confirm its quality, making it a stellar choice. Installation should be from the top, ensuring the arrows indicate upward gas flow. Follow a meticulous process including chimney sweeping and pot inspection for optimal performance. Maintenance involves regular sweeping, at least annually for solid fuel appliances.
