Product Overview
The Long Tail Increasing MI-FLEX Adaptor is engineered from high-quality 316L stainless steel to offer durability, longevity and a sleek, natural finish that complements any chimney system.

Installation and Safety
Installation is Key:
When it comes to installing your Long Tail Increasing MI-FLEX Adaptor, following recommended guidelines is vital for ensuring not only the performance of your chimney system, but also its safety. The installation requires the use of a high-temperature sealant, such as fire cement or ceramic rope, to secure the adaptor between the rigid flue and the flexible liner. It is important that the MI-FLEX liner is fully enclosed within a masonry chimney, as dictated by Building Regulations Document J, to avoid issues that can arise with non-masonry enclosures, such as timber or plasterboard.
Safety Considerations:
For your peace of mind, remember that safety does not end at installation. Regular maintenance is imperative, especially with solid fuel systems. We highly recommend that you schedule annual inspections and at least bi-annual sweeping by a HETAS registered professional. This not only ensures efficient operation but also dramatically reduces potential fire hazards associated with soot and creosote build-up.

Even if your existing setup seems functional, the improved airflow and secure seal provided by the adaptor can lead to a more efficient and safer chimney system. Concerns about installation are easily mitigated by following the detailed instructions and using the proper sealants. For those unfamiliar with chimney maintenance, professional installation and regular servicing are recommended.
