The Increasing MI-FLEX Adaptor Ø 180-Ø 200 is an essential component for creating a seamless flue system. Constructed from high-quality 0.6mm 316 stainless steel, this adaptor ensures durability and reliability. It is specifically designed to serve as a transitional joint, connecting rigid single wall flue systems to MI-FLEX 316 and 904 flexible flue liners.
These flexible flue liners are suitable for multi-fuel applications, including wood with less than 20% moisture, smokeless coal, gas, and oil, operating at temperatures up to 600°C (T600 designation). Meeting Building Regulations Document J, this adaptor must be fully enclosed within a masonry chimney for safe and efficient operation. The adapter effectively increases the diameter by 20mm, aiding in the smooth transition from one diameter to another, ensuring a gas-tight seal when used with appropriate materials like fire cement or high-temperature sealant.
It's crucial for the adaptor to be easily accessible for chimney sweeping and maintenance by a competent person, such as a HETAS registered professional. Proper cleaning and inspection ensure the longevity and functionality of the entire chimney system, with recommendations to perform these tasks at least twice a year for solid fuel applications.
