Choosing the correct liner size for NEW chimneys.

“New masonry chimneys should be constructed with flue liners suitable for the intended application”.

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.

The usual solution is to drop a steel flexible steel liner down, incurring additional time and expense (up to £1,000 per property) and contravening Building Document J.

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