Premium Materials
The use of 316L stainless steel not only enhances the product's durability but also provides resistance to corrosive elements present in the combustion of different types of solid and liquid fuels. This material is favoured by professionals who demand reliability and longevity from their chimney installations.
Dual-Layer Construction
The unique double-skinned design ensures that both the internal and external surfaces of the flue liner maintain optimal heat distribution. This innovative approach prevents thermal shock, which can damage the chimney structure over time.
Omega-Lock Sealing System
A critical aspect of any flue liner is the ability to maintain a secure and leak-proof installation. The Omega-Lock seal in this liner provides a tight and secure fit, minimising the risk of gas leaks and enhancing overall system safety. This feature is particularly important for installations in older chimneys where additional reliability is required.
Lifetime Warranty with Screw-FIX Accessories
Investing in the Mi-FLEX flue liner also means benefitting from a lifetime warranty when installed with the recommended Screw-FIX accessories. This warranty is a testament to the manufacturer's confidence in the product’s performance and durability.
Installation Process and Considerations
Installing the 316L Mi-FLEX flue liner is designed to be as straightforward as possible. Begin by inspecting your chimney for any potential issues such as blockages or structural weaknesses. A thorough chimney sweep is essential before proceeding with the installation. Then, starting at the top, align the liner ensuring that the directional arrows point upward. This is vital to maintain the correct flow of exhaust gases. Once positioned, secure the liner using the Omega-Lock mechanism and the recommended Screw-FIX accessories. If you encounter any difficulties during the installation process, it is advisable to consult with a professional installer to ensure the safety and efficiency of your system.
Maintenance and Long-Term Benefits
Regular maintenance is crucial to ensure optimal performance of any flue liner. The robust construction of the Mi-FLEX flue liner minimises the need for frequent repairs, but an annual chimney sweep is recommended to prevent buildup and ensure unobstructed airflow.
