Pack 602 is designed for use within a masonry chimney following Building Regulations Document J. Ensure that any existing chimney pot is removed prior to installation. The flexible flue liner must be fully enclosed to guarantee safety and optimal performance. It is highly recommended to follow manufacturer guidelines and schedule a professional chimney sweep at least once a year, or twice for solid fuel appliances. Adhere strictly to the provided installation instructions and consult with a certified installer if you have any doubts during the process.

Pack 602 includes a 150mm top plate, top clamp, nose cone, adaptor to black pipe or single wall flue, chimney notice plate, and a rain cap.

The components are suitable for use with wood (under 20% moisture), smokeless coal, gas, and oil appliances up to 600°C.

This pack is specifically designed for use with MI-FLEX 316 and 904 flexible flue liners.

The T600 designation indicates that the components can withstand temperatures up to 600°C, making them suitable for a wide range of fuel types.

It's recommended to sweep your chimney at least once a year. For solid fuel appliances, sweeping should be performed at least twice a year—in the pre-heating and post-heating seasons.

No, Building Regulations Document J requires that a flexible flue liner can only be installed completely enclosed inside a masonry chimney. Non-masonry enclosures like timber or plasterboard boxing are not acceptable.

Yes, sweeping should be carried out by a competent person. For solid fuel applications, you can find HETAS registered sweeps at www.hetas.co.uk.
