Flue, Chimney and Soil or Vent pipes

Part J of the Building Regulations seeks to ensure, among other things, that there is adequate provision for the discharge of the products of combustion to the outside air through flues that create enough draught, can take the expected temperatures, are sufficiently gas tight, and discharge at locations away from openings into the building.

Flues and chimneys should be fixed in appropriate places.

Ventilation pipes should finish at least 900mm above any opening into the building within three metres.
