The Flex to Twin Wall Adaptor Ø 200 is a premier solution for connecting MI-Flues multi-fuel liners to TWPro Twin Wall Chimneys. This unit is crafted for use with solid fuel, gas, and oil appliances, including woodstoves, gas coal effect fires, and boilers. Constructed with dual layers of stainless steel, the outer skin is made from durable 304-grade stainless steel (0.4mm thick), while the inner skin boasts 316-grade stainless steel (0.4mm thick) for enhanced heat resistance and longevity.
The adaptor features compressed rockwool insulation, offering a density of 200kg/m3 to ensure superior thermal performance. For safety, a critical 50mm distance from combustibles must be maintained. The TWPro system secured by locking bands offers ease of installation, and the entire assembly is both HETAS approved and CE marked, ensuring compliance with strict safety standards.
Perfect for use inside existing Class 1 Chimneys, this adaptor transitions seamlessly with a screw-fix coupling, keeping flex hidden within the chimney structure.
