The 904L Mi-FLEX 125mm x 44m COIL is a top-tier double skinned flexible flue liner designed for relining masonry chimneys. Constructed with durable 904L grade stainless steel, both the inner and outer skins measure 0.105mm in thickness, ensuring longevity and performance. The smooth inner liner enhances airflow, while the convoluted outer skin provides added flexibility and strength.
This flue liner accommodates a variety of fuels, including gas, oil, coal, coke, cured dry logs, cured dry peat, and approved smokeless fuels. It carries the essential approvals from HETAS and CE, confirming its high standards. For installation, ensure the liner is fed from the top with arrows pointing upward to align with gas flow.
Secure it with a Nose Cone and string, easing it down the chimney for a perfect fit. Regular maintenance is advised, especially for chimneys serving solid fuel appliances, to keep it functioning optimally.
