The 316L Mi-FLEX 80mm x 1m Flexible Flue Liner is designed meticulously for relining masonry chimneys. Made from 316L grade stainless steel, both the inner and outer skins are 0.105mm thick, ensuring robust construction and longevity. The flue liner is compatible with various fuel types including gas, oil, coal, coke, cured dry logs, and peat.
Featuring a smooth inner liner and a convoluted outer skin, the Mi-FLEX employs an innovative Omega-Lock seal constructed from a single strip of steel for superior performance and durability. Approved and listed by HETAS as well as CE certified, this flue liner ensures safety and compliance with industry standards. Installation is straightforward but ensure your chimney is swept and the pot is in good condition.
Regular maintenance is essential, especially for chimneys serving solid fuel appliances.
Before installation, ensure that your chimney is thoroughly swept and free from obstructions. The liner must be installed from the top of the chimney with the arrows clearly pointing upwards. For an optimal installation, use the appropriate Nose Cone accessory (sold separately) to aid in pulling the liner through the chimney. It is recommended that a professional installer verifies that your chimney pot is in good condition, or, if not using a suspended cowl, that you remove the pot from the stack. Regular maintenance is essential, particularly in chimneys serving solid fuel appliances, which should be inspected and cleaned at least once a year.

Comprehensive Buyers Guide for the 316L Mi-FLEX 80mm x 1m Flexible Flue Liner
When it comes to maintaining a safe and efficient home, the chimney plays a pivotal role. The 316L Mi-FLEX 80mm x 1m Flexible Flue Liner is designed specifically for homeowners and trade professionals who demand a product that combines durability, versatility, and ease of installation. In this guide, we aim to provide you with all the details necessary to make an informed purchasing decision, address common concerns, and help you understand how this product fits into your overall chimney maintenance strategy.
Why the 316L Mi-FLEX is a Standout Choice
Premium Material and Construction:
- The liner is crafted from 316L grade stainless steel, renowned not only for its excellent resistance to corrosion but also its ability to withstand high temperatures. Both inner and outer skins measure 0.105mm in thickness, ensuring that the liner maintains structural integrity over time.
Innovative Seal Design:
- Featuring the innovative Omega-Lock seal, the liner ensures a secure, leak-proof installation. This robust design, formed from a single continuous strip of steel, is folded in a way that eliminates potential weak points, thus reducing the risk of leaks and improving overall performance.
Versatility Across Fuel Types:
- Whether you use wood, oil, gas, or low sulphur coal, this flue liner is engineered to handle multiple fuel types seamlessly. Its flexibility and durability mean that it is just as effective in a variety of environments, making it an ideal solution for most domestic chimneys.
Certifications and Warranty:
- Safety is paramount, and the 316L Mi-FLEX comes fully approved by HETAS and carries CE certification, ensuring that your installation meets contemporary building safety standards. Moreover, a lifetime warranty offers added peace of mind, certifying the product’s long-term reliability.
Installation: What You Need to Know
Proper installation is critical to reap the full benefits of any flue liner. Before starting, ensure that your chimney has been swept and is free from blockages. The installation process should always begin from the top of the chimney, with clear indicators (arrows) showing the correct upward direction. It is strongly recommended to use a Nose Cone accessory for pulling the liner through to avoid any damage during installation. If your chimney features a pot, verify that it is in good condition; otherwise, consider removing it when not using a suspended cowl.
Maintenance and Longevity
To maintain the efficiency of your chimney, regular maintenance is essential. For inhabitants of older homes or those using solid fuel appliances, an annual inspection and sweep are advised to avoid buildups that could compromise the liner’s performance. The high resistance of 316L stainless steel to contaminants and high temperature ensures that, with proper care, the liner will perform reliably throughout its lifespan.
Comparing Flue Liner Options
Before making your final decision, it is beneficial to compare this product with other available options. The unique construction of the Mi-FLEX, including its dual-layer build and Omega-Lock seal, sets it apart from conventional liners that may use lower-grade materials or less sophisticated sealing methods. While competitors might offer similar products, the combination of 316L stainless steel, flexible installation, and comprehensive certifications makes the Mi-FLEX an intelligent investment for any property.
Addressing Common Objections
Cost Considerations:
- Although the initial investment in a high-quality flue liner might seem steep, consider the long-term savings on maintenance and the enhanced safety it provides. A robust liner ensures higher energy efficiency and can prevent costly damage due to poor chimney function.
Installation Concerns:
- Some customers may worry about the challenges of installation. However, when installed correctly—ideally by a professional—the process is straightforward. Additionally, using recommended accessories simplifies the procedure and reduces potential risks.
Fuel Compatibility:
- With its multi-fuel design, the 316L Mi-FLEX covers a broad spectrum of heating requirements. This versatility means that even if your fuel type changes over time, the liner remains a viable and effective solution.
