For optimal performance, the MI-FLEX Adaptor must be installed within a masonry chimney. Ensure that the adaptor is securely fixed using appropriate fire cement, ceramic rope, or high-temperature sealant at all connection points. It is crucial to obtain a gas-tight seal during installation. Before commencing work, verify that all components are clean and free from debris. Always adhere to the UK Building Regulations Document J, which mandates that flexible flue liners (and associated adaptors) are completely enclosed within a masonry structure. Regular maintenance, particularly sweeping for solid fuel applications, is recommended to keep the system operating safely and efficiently.

The MI-FLEX Adaptor is made from 1mm thick 316 stainless steel, providing excellent durability and resistance to high temperatures.

The MI-FLEX Adaptor is specifically designed for use with MI-FLEX 316 and 904 flexible flue liners of the same diameter.

This adaptor is suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil appliances.

Yes, this adaptor meets all the requirements of the UK Building Regulations Document J regarding installation within masonry chimneys.

To achieve a gas-tight seal, use fire cement, ceramic rope, or high-temperature sealant at all connection points.

For solid fuel applications, chimneys should be swept at least twice a year – at the end of the heating season and before it begins again. For other fuels, annual sweeping by a competent person is recommended.

No, according to Building Regulations Document J, flexible flue liners, including the MI-FLEX Adaptor, must be fully enclosed within a masonry chimney.
