The Top Clamp - Ø 300 is a crucial component for ensuring the stability and effectiveness of your chimney system. Perfectly designed for use with MI-FLEX 316 and 904 flexible flue liners, this top clamp provides essential support by bearing the vertical weight of the flue liner at the top of the stack. All MI-FLEX accessories, including this top clamp, comply with Building Regulations Document J, which mandates that a flexible flue liner must be installed completely enclosed inside a masonry chimney.
The top clamp is suitable for appliances operating at temperatures up to 600°C (T600 designation), making it ideal for use with wood (under 20% moisture), smokeless coal, gas, and oil. For optimal functionality, ensure that the chimney stack is fully weatherproofed and of sound construction, and that all chimney pots are in good condition with appropriate flaunching. Regular maintenance and sweeping are essential for safe operation, particularly with solid fuel appliances.
Adhering to recommended cleaning schedules will help prevent blockages and ensure long-term efficiency.
