The Top Clamp - Ø 80 is a crucial accessory for the secure installation of MI-FLEX 316L and 904 flexible flue liners, forming a comprehensive chimney system. Designed for use with your multi-fuel flue liner, this clamp supports up to 600°C (T600) and is suitable for wood with less than 20% moisture, smokeless coal, gas, and oil. As per Building Regulations Document J, this clamp must be used within a masonry chimney.
The chimney stack should be prepped to be fully weatherproofed and in good condition before installation. This reliable top fixing ensures the vertical stability of your flue liner, working in tandem with the Top Plate and Top Insert Sleeve to support the liner at the top of the chimney stack. Regular maintenance is essential for longevity and efficiency, and chimneys serving solid fuel appliances should be swept at least twice annually by a HETAS registered sweep.

MI-FLEX Top Clamp - Ø 80 Buyers Guide
When installing a chimney system, the security of each component can greatly influence the overall performance and safety of your heating installation. The MI-FLEX Top Clamp - Ø 80 plays a vital role by offering a robust connection point to support your flexible flue liner. In this comprehensive guide, we explore why this product is indispensable for ensuring a secure, efficient, and compliant chimney installation.
Key Features and Benefits
Robust Material Construction:
- Built from high-grade 316L stainless steel, this top clamp promises durability and minimal maintenance. The inherent strength of 316L ensures that it can resist the harsh elements and corrosive conditions often encountered within a chimney system.
High Temperature Endurance:
- Designed to withstand temperatures up to 600°C, this clamp is perfect for high-performance applications. Whether you’re burning wood with less than 20% moisture, oil, gas, or smokeless coal, the MI-FLEX Top Clamp remains reliable even at elevated temperatures.
Masonry Chimney Specific Design:
- The clamp is specifically engineered for masonry chimneys, ensuring a tight and secure fit when paired with other MI-FLEX components such as the Top Plate and Top Insert Sleeve. This is critical for meeting the safety requirements outlined in Building Regulations Document J.
Comprehensive System Integration:
- When used in tandem with accompanying components, the MI-FLEX Top Clamp forms part of a complete system that supports the vertical weight of your flue liner. This synergy not only bolsters the structural integrity of the chimney but also simplifies maintenance and future inspections.
Installation Considerations
Pre-Installation Checks:
Before proceeding with the installation, a few essential steps must be taken:
- Ensure the masonry chimney is fully weatherproofed and free of any significant structural defects.
- Confirm that the chimney stack has been prepped, with appropriate flaunching completed and all chimney pots in optimal condition.
- Only proceed with the installation if the chimney has been verified as a masonry structure since non-masonry enclosures are not suitable for this product.
Professional Guidance:
- The instructions provided by MI-FLEX are clear, but it is always advisable to engage with a certified professional. The installation should be performed by someone experienced in handling flue liners to ensure that all components are correctly installed and in compliance with current safety regulations.
Maintenance and Long-Term Care
Maintaining your chimney once the MI-FLEX Top Clamp is installed is crucial for long-term success:
- Regular Inspections: Ensure that the chimney system is inspected at least once a year. For systems that service solid fuel appliances, bi-annual sweeping is recommended by HETAS registered sweeps.
- Scheduled Cleanings: Regular cleaning will prevent the buildup of soot and debris, which could compromise the fixture’s performance.
- Immediate Repairs: Should any issues be detected during inspections, address them immediately to avoid compromising the system’s integrity.
