Installation must be performed in accordance with the provided guidelines and safety regulations. Begin by ensuring the wall section selected for installation is non-combustible or maintains a minimum distance of 375mm from any combustible materials. The MI-VIT Lite Adjustable Wall Support should always be positioned so that the smaller diameter points downward to ensure that any condensate remains within the flue system. Due care should be taken when cutting the support to size; any exposed steel must be treated with high temperature paint to prevent rusting. Always use appropriate Personal Protective Equipment (PPE) and, if necessary, consult a professional installer to confirm compatibility with your specific flue liner, chimney stack, or twin wall system. Optional accessories such as additional sealing products for pellet installations or adjustable brackets for enhanced support can be sourced separately to further optimise your installation.

The MI-VIT Lite is suitable for gas, oil, and solid fuel appliances with temperatures up to 600°C.

No, MI-VIT Lite pipes should not be used to pass through ceilings or combustible walls.

The smaller diameter should always be pointing downward to ensure condensates stay within the flue system.

For high temperature installations up to T600, no sealing is required. However, for pellet installations where positive pressure (P1) is present, seals must be placed on every joint.

For solid fuel applications, it's recommended to clean the chimney at least once a year or as frequently as necessary.

Yes, it can be cut, but exposed steel must be treated with high temperature paint to prevent rusting.

Always wear appropriate Personal Protective Equipment (PPE) during installation and ensure the pipe is not installed within 375mm of combustible materials.
