Pack 702 is an all-inclusive installation kit perfectly designed for use with MI-FLEX 316 and 904 flexible flue liners, ensuring your chimney system is both robust and efficient. Leveraging advanced MI-FLEX technology, this kit supports installations that comply with Building Regulations Document J, which mandates that flexible flue liners be enclosed within masonry chimneys. Capable of handling temperatures up to 600°C (T600 designation), it’s suitable for use with wood (moisture content <20%), smokeless coal, gas, and oil appliances.

The kit includes a top plate, top clamp, nose cone, adaptor to black pipe or single wall flue, a chimney notice plate, and a rain cap—all in a standard 180mm diameter. Maintenance is straightforward: sweep and inspect your chimney system at least annually, or bi-annually for solid fuel appliances. Ensure sweeping is done by a HETAS registered professional, and avoid using chemical cleaners or mild steel tools to keep your stainless-steel chimneys in top condition.

This pack is ideal for scenarios where you need to remove an existing chimney pot or if your chimney does not currently have one, giving you all the necessary components for a reliable and long-lasting installation.
