The Top Insert Sleeve Ø 180 is a crucial accessory in the MI-FLEX 316 and 904 flexible flue liner range. Designed for flawless compatibility, this sleeve ensures a secure fit at the top of your chimney installation. Engineered to withstand temperatures up to 600°C, it is suitable for use with various fuels, including wood (with less than 20% moisture), smokeless coal, gas, and oil.

Compliance with Building Regulations Document J is vital, as it mandates that flexible flue liners must be fully enclosed within a masonry chimney, ruling out non-masonry enclosures like timber or plasterboard. The Top Insert Sleeve works in tandem with the Top Plate and Top Clamp, ensuring the flue liner's weight is effectively supported without compromising its integrity. Regular maintenance is essential for longevity and safety, with an annual inspection recommended, and bi-annual sweeping for solid fuel appliances to remove deposits and blockages.

Let’s keep your chimney system reliable and efficient with this top-tier product from National Flues.

The Top Insert Sleeve must be installed within a fully masonry chimney as mandated by Building Regulations Document J. It should be properly aligned with the Top Plate and Top Clamp to guarantee that the lightweight yet resilient flexible flue liner is correctly supported. Prior to installation, consult the manufacturer's guidelines and ensure that all components are free from damage. Regular maintenance, including an annual inspection and bi-annual sweeping for solid fuel systems, is crucial to mitigate any risks associated with deposit build-up. Always employ the correct tools and professional assistance where necessary.

The Top Insert Sleeve Ø 180 is used to secure and support the flexible chimney liner at the top of the installation, in conjunction with the Top Plate and Top Clamp.

This sleeve is specifically designed for use with MI-FLEX 316 and 904 flexible flue liners.
