The Top Insert Sleeve with Rain Cap - Ø 125 is an essential component within the MF20 MI-FLEX range. Specifically designed to seamlessly integrate with MI-FLEX 316 and 904 flexible flue liners, this accessory ensures a complete and efficient chimney system when used together. According to Building Regulations Document J, flexible flue liners must be installed exclusively within masonry chimneys, not in timber or plasterboard enclosures.
Capable of withstanding temperatures up to 600°C, it is suitable for various fuel types including wood with less than 20% moisture, smokeless coal, gas, and oil. This product not only protects your flue from rain and pest ingress but also facilitates easier installation and secure clamping with its integrated protection sleeve. Maintenance is crucial, and we recommend biannual sweeping and inspection by a certified professional to ensure optimal performance and safety.
