The Top Clamp Ø 150 is a vital component in the installation of flexible flue liners. Specifically designed for use with MI-FLEX 316 and 904 flue liners, this top clamp ensures a secure and stable fit at the top of your chimney stack. It's perfect for multi-fuel applications, handling temperatures up to 600°C (T600 designation), and works seamlessly with wood (under 20% moisture), smokeless coal, gas, and oil appliances.
Compliance with Building Regulations Document J is essential, stipulating that flexible flue liners must be enclosed in a masonry chimney. Before installation, ensure your chimney stack's structure is sound, all chimney pots are crack-free, and proper flaunching is applied at the stack's top. Ensure your chimney system allows for easy sweeping and maintenance by professional sweeps, ideally twice a year for solid fuel applications.
