Outstanding Features and Benefits
Premium Material Quality
Constructed entirely from 316L stainless steel, the liner is exceptionally resistant to corrosion and temperature variations. This ensures that even in demanding environments, the product maintains structural integrity and performance. The dual skin construction not only enhances durability but also provides excellent thermal insulation, optimising your chimney's efficiency.
Innovative Omega-Lock Seam
One of the core innovations behind the Mi-FLEX coil is its Omega-Lock seal. This technology involves bending a single strip of steel at 180 degrees and folding the seam in four planes. The result is a uniquely secure and robust bond that minimises leak risks and ensures safety during long-term use. This essential feature is particularly beneficial in maintaining a tight seal within the chimney, preventing any harmful emissions from escaping.

This ensures that regardless of your heating system's fuel type, this versatile liner can meet your needs efficiently. Whether you are running a modern oil-fired system or a traditional wood-burning setup, this product adapts seamlessly to your requirements.
Accredited Approvals and Warranty
Safety is paramount, and this product has achieved HETAS and CE approvals. These certifications guarantee that the liner meets stringent UK safety and performance standards. Additionally, when installed with Screw-FIX accessories, you benefit from a lifetime manufacturer’s warranty, underscoring the product’s reliability and the confidence of both National Flues and Mi-Flues Ltd in its long-term performance.
Detailed Installation Guidelines
Pre-Installation Checks
Before installation, it is crucial to ensure that the chimney has been thoroughly swept and is free from obstructions or damage. Inspect the pot to confirm it is in good condition, particularly if you are not using a suspended cowl. These preliminary steps are vital for ensuring a smooth and safe installation process.
Step-by-Step Installation
1. Initial Setup: Begin by preparing the chimney, ensuring all debris is removed and the internal structure is sound.
2. Positioning the Liner: Carefully lower the liner into the chimney from the top. Pay close attention to ensure that the directional arrows on the liner face upwards, reflecting the correct gas flow direction.
3. Securing the Liner: Utilize the provided nose cone and pull string to secure the liner in place. This step guarantees that the liner remains aligned properly during operation.
4. Final Adjustments: If necessary, integrate optional accessories such as support brackets to enhance stability and ensure a precise fit.
Post-Installation Considerations
After installation, regularly inspect the liner and the surrounding structure to ensure that everything remains secure and that no maintenance issues arise. Routine checks, especially during periods of heavy usage, can greatly extend the life of your chimney system.
