The Screw-FIX Top Hat Adaptor - Ø 175 is an essential component for constructing a secure and efficient chimney system. Specifically designed for use with MI-FLEX 316 and 904 flexible flue liners, this adaptor ensures a strong, gas-tight seal. Suitable for appliances running up to 600°C, it can handle wood with less than 20% moisture, smokeless coal, gas, and oil.

Regulations require flexible flue liners to be entirely enclosed inside a masonry chimney, ensuring both safety and efficacy. To guarantee a perfect transition from the connecting flue system to the flexible liner, the adaptor must be securely fitted at the base of the chimney below the register plate, offering a clean and professional finish. Regular maintenance and sweeping by a competent person are recommended at least once a year, especially for solid fuel systems.

Follow HETAS guidelines for a safe, long-lasting chimney.

• Install the adaptor at the base of the chimney directly below the register plate. • Ensure the adaptor is completely enclosed within a masonry chimney, in line with current building regulations. • Use a high-temperature sealant, such as fire cement, ceramic rope, or high-temperature tape, to secure the connection and maintain a gas-tight seal. • Annual inspection and sweeping by a HETAS registered professional are recommended to ensure optimum performance and safety.

Yes, it is suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil appliances up to 600°C.

It should be installed at the base of the chimney below the register plate, making sure it transitions smoothly to the flexible flue liner, with the connection made inside the masonry chimney.

No, building regulations require that flexible flue liners be completely enclosed within a masonry chimney. Non-masonry enclosures such as timber or plasterboard are not acceptable.

Annual sweeping and inspection by a competent person are recommended, with more frequent sweeping for solid fuel systems. Avoid using chemical cleaners or mild steel tools.

Use fire cement, ceramic rope or tape, or high-temperature sealant to secure the connection points and create a gas-tight seal.
