The MI-FLEX Adaptor 1mm - Ø 150 is designed to provide a seamless connection between a single wall rigid flue system and a MI-FLEX 316 or 904 flexible flue liner with the same nominal diameter. This adaptor is part of our MF20 MI-FLEX accessory range, ensuring a comprehensive chimney system when used in conjunction with MI-FLEX liners. Perfect for multiple fuel types, including wood with less than 20% moisture, smokeless coal, gas, and oil, it handles temperatures up to 600°C.
Compliance with Building Regulations Document J is crucial, as it's essential that flexible flue liners are completely enclosed within a masonry chimney. Any exposed flex must be avoided and connections should be gas-tight, using fire cement, ceramic rope, tape, or high-temperature sealant. Regular maintenance, including sweeping by a competent person, ensures optimal performance and longevity of your chimney system.
