The Top Clamp - Ø 80 is a crucial accessory for the secure installation of MI-FLEX 316L and 904 flexible flue liners, forming a comprehensive chimney system. Designed for use with your multi-fuel flue liner, this clamp supports up to 600°C (T600) and is suitable for wood with less than 20% moisture, smokeless coal, gas, and oil. As per Building Regulations Document J, this clamp must be used within a masonry chimney.
The chimney stack should be prepped to be fully weatherproofed and in good condition before installation. This reliable top fixing ensures the vertical stability of your flue liner, working in tandem with the Top Plate and Top Insert Sleeve to support the liner at the top of the chimney stack. Regular maintenance is essential for longevity and efficiency, and chimneys serving solid fuel appliances should be swept at least twice annually by a HETAS registered sweep.
