Description Increasing MI-FLEX Adaptor – 125mm-150mm: Seamless Transition for Flue Systems The Increasing MI-FLEX Adaptor – 125mm-150mm is a meticulously engineered 0.6mm 316 stainless steel adaptor designed to create a seamless transition, connecting a ridged single-wall connecting flue system to MI-FLEX. This specific adaptor allows for an increase of up to 25mm from the single wall to the flexible flue liner. Overview: A vital component within the MF20 MI-FLEX accessories collection, tailored precisely for compatibility with MI-FLEX 316 and 904 flexible flue liners. When installed in conjunction, it contributes to creating a comprehensive and efficient chimney system. General Application: Designed to work in harmony with MI-FLEX Multi-fuel flexible flue liners, adhering to the stringent requirements stipulated in Building Regulations Document J. This adaptor ensures that a flexible flue liner is completely enclosed within a masonry chimney. Suitable for appliances operating at temperatures up to 600 degrees (T600 designation) and compatible with Wood. Bottom Fixings: Bottom fixings play a crucial role in facilitating the transition from the connecting flue system to the flexible flue liner. Ensuring that the connection to the flex remains within the confines of the existing masonry chimney and that no flex is exposed at any point. Proper provisions must be made to secure the bottom fixing into the connecting flue below and the flexible above to create a gas-tight seal. Utilization of fire cement, ceramic rope or tape, or high-temperature sealant is recommended for a secure installation. Specific Application: Crafted with precision, this 0.6mm 316 stainless steel adaptor serves as a transitional joint, facilitating a seamless connection between a ridged single-wall connecting flue system and MI-FLEX. Notably, it allows for an increase of up to 25mm from the single wall to the flexible flue liner, ensuring a smooth transition. Maintenance: For optimal performance, the chimney system must be designed to facilitate easy access for sweeping and maintenance, carried out by competent personnel. Solid fuel applications should refer to HETAS registered sweeps for proper maintenance guidance. Avoid the use of chemical cleaners or mild steel tools on stainless steel chimneys. Regular cleaning and inspection, at least annually, are recommended, along with biannual sweeping for chimneys serving solid fuel appliances, preventing potential blockages or deposits.
