Before installation, ensure that the existing masonry chimney and flue liner system are in good condition and comply with current Building Regulations. Pack 706 is designed for installations where the chimney pot remains in place. Follow the manufacturer's guidelines carefully: securely fix the Pot Hanging Cowl with Mesh, attach the Nose Cone correctly, and use the Increasing Adaptor to transition safely to Black Pipe or Single Wall Flue. Regular maintenance, including routine chimney sweeps by a competent person, is recommended to ensure lasting performance. Optional accessory components are available should your installation require additional customisation.

Pack 706 is specifically designed for use with MI-FLEX 316 and 904 flexible flue liners, ensuring optimal compatibility and performance.

No, Pack 706 is designed for installations where you do not wish to remove the existing chimney pot.

The kit is suitable for use with wood (less than 20% moisture), smokeless coal, gas, and oil.

Pack 706 is suitable for appliances with temperatures up to 600°C (T600 designation).

Your chimney system should be inspected and swept at least once a year. For solid fuel appliances, it is recommended to sweep the chimney twice a year: at the end of the heating season and before the start of the next season.

No, you should not use chemical cleaners or mild steel tools to sweep stainless steel chimneys. Always opt for professional sweeping services.

Maintenance should be carried out by a competent person. For solid fuel applications, a list of HETAS registered sweeps can be found at www.hetas.co.uk.
