The MI-VIT Lite Adjustable Pipe 300mm (Ø 125) is an essential component for your flue system. Perfectly suited for gas, oil, and solid fuel appliances, this adjustable pipe can handle temperatures up to 600 degrees Celsius, ensuring your heating appliances operate efficiently. Constructed from zero carbon steel with a durable vitreous enamel coating in a sleek matt black finish, this pipe is designed for robust performance and long-lasting use.

It is essential for connecting your appliance to a Flue Liner, Chimney Stack, or Twin Wall Flue System but must not be used to pass through ceilings or combustible walls. Installation is straightforward—ensure the smaller diameter points downward so condensation stays within the flue system. When dealing with high-temperature installations (up to T600), the friction fit joint does not require sealing.

For P1 pressure applications, seals must be used at every joint. This pipe also comes with a clamp for secure attachment. It is advised not to cut the pipe; if necessary, protect any exposed steel with high-temperature paint to prevent rusting.

Routine maintenance is crucial, especially for solid fuel appliances. Ensure you install access doors at direction changes for easy cleaning, and remember to sweep chimneys serving solid fuel appliances at least once a year.

When installing the MI-VIT Lite Adjustable Pipe, ensure that the smaller diameter end is orientated downwards to maintain proper condensate management within the flue system. For high-temperature (up to T600) applications, the friction fit joint does not require any additional sealing; however, if used in P1 pressure installations, every joint must be sealed. The integrated clamp is provided for enhanced stability. It is important to avoid running this pipe through ceilings or combustible walls. Should any cutting be necessary, ensure that any exposed steel is protected with a high-temperature paint to prevent rusting. Regular inspection and maintenance are strongly recommended, especially for systems serving solid fuel appliances. Install access doors at directional changes to facilitate easy cleaning and periodic sweeping to maintain clear flue passages.
