The Top Clamp - Ø 250 is a crucial installation accessory from the MF20 MI-FLEX range, engineered explicitly for use with MI-FLEX 316 and 904 flexible flue liners. This top clamp is instrumental in creating a fully functional chimney system. It effectively supports the vertical weight of the flue liner when used in conjunction with the Top Plate and Top Insert Sleeve at the stack's top.
Suitable for multiple fuel types including wood with less than 20% moisture, smokeless coal, gas, and oil, this clamp withstands temperatures up to 600°C (T600 designation). As per Building Regulations Document J, it is mandatory to install flexible flue liners completely enclosed within masonry chimneys, excluding any non-masonry enclosures such as timber or plasterboard boxing. The chimney structure must be sound and properly weatherproofed before installation.
Regular sweeping and maintenance, conducted by competent persons such as HETAS registered sweeps, ensure optimal performance and longevity of the chimney system. This should be done at least once a year or twice for solid fuel appliances.
Installation is straightforward yet vital for optimal chimney performance. The Top Clamp - Ø 250 must be used in conjunction with the Top Plate and Top Insert Sleeve to effectively support the weight of the MI-FLEX flexible flue liners. Ensure that your chimney system is fully contained within a masonry structure as stipulated by Building Regulations Document J. It is imperative that you inspect the chimney's condition – the masonry must be sound, stable, and fully weatherproofed prior to installation. After fitting, regular maintenance is recommended: a sweep by a HETAS registered professional at least once a year for gas or oil systems, and twice a year if you use solid fuels like wood or smokeless coal. Do not attempt installation on non-masonry enclosures such as timber or plasterboard boxing, as this can compromise the integrity of the chimney system and pose safety risks.
