Choosing the correct liner size for NEW chimneys.

This statement from Building Document J is critical; however, a common issue is that many newly built chimneys rely on flexible liners to allow a stove installation, because the typically 225mm clay/concrete system specified has too wide a diameter for the appliance.

Document J clearly states: “Flexible flue liners should be used only to RELINE a chimney and should not be used in a new chimney”.
