In this comprehensive buyers guide, we will explore the key features, benefits, installation steps, and answer common queries regarding this high-performance flue adaptor.
Understanding the Product
The KC Twin Wall to Flex Adaptor - Ø 175 is constructed with two distinct stainless steel layers – the inner layer being 316L stainless steel, and the outer 304 grade. Both layers are engineered with a thickness of 0.40mm, ensuring durability and resistance even under extreme temperatures.

• Safety Certifications: With HETAS approval and CE marking, the adaptor meets the stringent safety requirements necessary for modern installations, ensuring that you remain compliant with current regulations.
• Easy Integration: The locking band mechanism simplifies installation by providing a secure joint between your KC Twin Wall system and the MI-Flues flexible liner. This ease of integration means less time spent on installation and more confidence in the overall setup.

Begin by carefully aligning the adaptor within the class 1 chimney, ensuring that the transition point where the twin wall system meets the flexible liner is positioned correctly. Secure the unit using the built-in locking band mechanism which offers a dependable connection. It is crucial to maintain a minimum distance of 60mm from any combustible material around the external edge of the flue. By meticulously following these safety steps, you are ensuring not only a secure installation but also optimal performance and peace of mind.
