The Screw-FIX Top Hat Adaptor - Ø 80 is a versatile accessory meticulously crafted for seamless integration with MI-FLEX 316 and 904 flexible flue liners. This adaptor plays a critical role in ensuring a full chimney system is achieved when installed according to Building Regulations Document J. It is designed for use with a variety of appliances, including wood (less than 20% moisture), smokeless coal, gas, and oil, all of which can operate at temperatures up to 600°C (T600 designation).
The adaptor must be entirely enclosed within a masonry chimney, as non-masonry enclosures such as timber or plasterboard are not acceptable. For installation, the bottom fixing must be secured both to the connecting flue below and the flexible liner above to form a gas-tight seal, using appropriate materials like fire cement, ceramic rope, or high-temperature sealant. The unit also facilitates routine maintenance and cleaning, which should ideally be conducted by a HETAS registered professional, especially for solid fuel applications.
