The Joiner Ø 150 is a highly durable and essential accessory designed to join two sections of MI-FLEX multi-fuel flexible flue liners. Perfect for use with MI-FLEX 316 and 904 liners, this joiner ensures a complete and efficient chimney system. Compliant with Building Regulations Document J, this joiner is ideal for use with wood (below 20% moisture), smokeless coal, gas, and oil appliances up to 600°C (T600 designation).
It is crucial that the flexible flue liner is installed entirely within a masonry chimney, as non-masonry enclosures such as timber or plasterboard are not acceptable. Regular maintenance, including annual chimney sweeping by a competent person, ensures longevity and performance. For solid fuel applications, refer to HETAS registered sweepers to maintain your system in top condition.
