A boiler flue is a pipe that enables the dangerous gases that are omitted from the boiler to be safely removed and directed away from the property into the atmosphere outside.
The flue is designed to remove water vapour, carbon dioxide and even carbon monoxide gases away from the boiler and property. It is important these are maintained and working correctly to keep you safe.
A minimum of 300mm of free airspace with 1 meter in front of the flue must be kept.
Structures such as awnings, sheds, conservatories must not be constructed within the flue.
