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.

The MI-FLEX Adaptor 1mm - Ø 150 is an essential component for homeowners and professionals seeking to upgrade their chimney systems. Crafted from high-grade 316L stainless steel, this adaptor is designed to provide a seamless connection between a rigid flue system and a MI-FLEX flexible liner. Whether you are replacing an old system or installing a new one, understanding the benefits and correct installation process of this product is crucial for maintaining the efficiency and safety of your heating system.
Key Features and Benefits
High-Quality Materials:
The adaptor is manufactured from 316L stainless steel, ensuring it is long-lasting, resistant to corrosion, and capable of withstanding high temperatures up to 600°C. This durability is particularly important in chimney applications where thermal stress is a constant factor.
Seamless Connection:
Designed for a perfect match with MI-FLEX liners, the adaptor simplifies the process of transitioning from a rigid flue system to a flexible liner. This results in improved installation efficiency and a reduction in potential installation errors.
Multi-Fuel Compatibility:
From wood with less than 20% moisture to gas, oil, and smokeless coal, the MI-FLEX Adaptor is specially engineered to support a wide range of fuel types. This versatility ensures that your chimney system remains compliant and functional regardless of your heating preferences.
Compliance and Safety:
Compliance with Building Regulations Document J is a key feature. The adaptor helps to ensure that your flexible flue liner is completely enclosed within a masonry chimney, thereby meeting stringent UK standards. This not only enhances safety but also prevents hazardous conditions related to improper ventilation.
Installation Guidance
Proper Installation is Key:
For optimal performance, the adaptor should be installed by a qualified professional. It is critical that the connection between the rigid flue and the flexible liner is made accurately to guarantee a gas-tight seal. Any gaps in the connection can compromise the safety of your system. Always use the recommended fire cement, ceramic rope, or high-temperature sealant during installation.
Regulatory Compliance:
Ensure that your installation adheres to local building regulations. Flexible flue liners must be fully enclosed within a masonry structure. Deviations from this can lead to safety risks and potential issues during future inspections or property sales.
Maintenance and Safety Checks:
After installation, regular maintenance is imperative. Engaging a HETAS registered chimney sweep at least once a year for gas appliances, and more frequently for solid fuel appliances, will help maintain the performance and safety of your system. Regular inspections not only prolong the life of your chimney but also prevent costly emergency repairs.
Optional Accessories and Complementary Products
While the MI-FLEX Adaptor serves as a standalone essential component, consider exploring other accessories that enhance your chimney system. High-temperature sealants, ceramic ropes, and fire cement are all valuable additions that ensure your system remains gas-tight and efficient. These accessories further optimise the connection between the rigid flue and the flexible liner, ensuring that your installation continues to meet the rigorous standards expected in modern chimney systems.
Addressing Common Concerns
Query: Will the adaptor work with any flue system?
Answer: The MI-FLEX Adaptor is specifically designed for use with a MI-FLEX 316 or 904 flexible flue liner of the same nominal diameter. It is crucial to ensure that your flue system matches these specifications.
Query: What about installation in non-masonry housings?
Answer: The adaptor is intended for use in masonry chimney installations only. Non-masonry enclosures are not compliant with current Building Regulations and can lead to safety risks.
Query: How do I ensure a secure connection?
Answer: Use appropriate sealants—fire cement, ceramic rope, or high-temperature sealant—to achieve a gas-tight seal. This not only improves the performance of your system but also enhances safety.
Query: Are there additional accessories to complement my installation?
Answer: Yes, exploring complementary MI-FLEX accessories is recommended. Items such as high-temperature sealants and ceramic ropes play an integral role in maintaining a secure connection and optimal chimney performance.
