The MI-VIT Lite - Adaptor to SW - Ø 125 is an essential component for connecting gas, oil, and solid fuel appliances to your existing flue system. Crafted from zero carbon steel with a durable vitreous enamel coating in a sleek matt black finish, this adaptor ensures efficient performance even at temperatures up to 600°C. For installations requiring pressure ratings, the MI-VIT Lite achieves a P1 rating up to 200°C when sealed appropriately.

It's important to note that this adaptor should not pass through combustible materials and must be installed with at least a 375mm clearance from such materials. Designed for a friction fit, this adaptor doesn't require joint sealing under high temperature installations, but seals are necessary for pellet installations where positive pressure is present (P1 applications). For added convenience, the MI-VIT Lite can be cut to size, with exposed steel being treated with high temperature paint to prevent rust.

Proper maintenance, including regular chimney sweeping and inspection, is crucial, particularly for solid fuel applications.

Installation requires that the adaptor be fitted with the smaller diameter pointing downward to ensure condensates remain inside the system. Maintain a clear distance of at least 375mm from any combustible material. This adaptor is designed for friction fit in high temperature installations, eliminating the need for joint sealing; however, when used in pellet installations where positive pressure is present, appropriate sealing must be applied. If cut to size, any exposed steel must be promptly treated with high temperature paint to combat rust. Always follow safety guidelines, including wearing appropriate PPE, and ensure regular chimney sweeping and inspections to maintain optimal performance.

This adaptor is used to connect gas, oil, and solid fuel appliances to existing flue systems, including flue liners, chimney stacks, and twin wall flue systems.

Yes, it is suitable for use with appliances operating at temperatures up to 600°C.

No, it should not be used to pass through ceilings or walls made of combustible materials.

Ensure it is installed with the smaller diameter pointing downward to keep condensates inside. Maintain a minimum clearance of 375mm from combustible materials and wear appropriate PPE.

Sealing is not required for T600 high temperature installations but is necessary for pellet installations where positive pressure is present.

Regular chimney sweeping and inspections, especially for solid fuel appliances, are recommended. Install access doors for easy inspection and cleaning.

Yes, it can be cut, but any exposed steel should be covered with high temperature paint to prevent rust.
