The Joiner - Ø 100 is a critical component in our MI-FLEX accessory range, engineered specifically for joining sections of MI-FLEX 316 and 904 flexible flue liners. Perfectly tailored for creating complete chimney systems, this accessory ensures seamless integration with your multi-fuel flexible flue liner installations. Strictly to be used within masonry chimneys, as laid out by Building Regulations Document J, it is suitable for wood with under 20% moisture, smokeless coal, gas, and oil appliances, enduring temperatures up to 600°C (T600 designation).
Note that this joiner must not be used on gas liners and is recommended solely for chimney liner extensions exceeding standard flex lengths. For optimal performance, annual or biannual sweeping by a HETAS-registered professional is strongly advised. Avoid chemical cleaners and mild steel tools to extend the lifespan of your stainless steel chimney system.
