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.
