The Screw-FIX Flex Joiner Ø 200 is a highly practical accessory from the MI-FLEX family, expertly designed to join two pieces of multi-fuel flexible flue liners like MI-FLEX 316 and MI-FLEX 904. This joiner is crucial when the chimney liner length surpasses the maximum available flex length. Perfect for use with applications up to 600°C, including wood (with less than 20% moisture), smokeless coal, gas, and oil, it meets stringent Building Regulations Document J requirements, ensuring it can only be installed enclosed within a masonry chimney.

The system ensures safety and efficiency, providing an excellent solution for a full system chimney. Remember to follow proper maintenance guidelines, which include sweeping by a competent person and avoiding chemical cleaners or mild steel tools for stainless steel chimneys. The flue system should be inspected and cleaned at least once a year, preferably twice for solid fuel appliances to avoid soot build-up and blockages.

Installation of the Screw-FIX Flex Joiner must be performed in accordance with manufacturer guidelines and Building Regulations Document J. It is essential that the product is installed within a fully enclosed masonry chimney. Prior to installation, ensure that the flue liners (MI-FLEX 316 or MI-FLEX 904) are correctly aligned and trimmed to size. Pay special attention to the following points: • Only use approved cleaning methods – do not use chemical cleaners or mild steel tools on stainless steel components. • Ensure that connections are secure and free from any deformities which could compromise safety. • All installations should be verified and, if necessary, conducted by a competent person to guarantee proper sweeping and maintenance. • Regular system checks and annual cleanings (or biannual for solid fuel applications) are strongly advised to avoid soot build-up and blockages. • Always refer to the full installation manual for detailed instructions and safety warnings.

No, the Screw-FIX Flex Joiner Ø 200 must not be used with gas liners. It is only suitable for multi-fuel flexible flue liners.
