Any air intake terminal MUST be installed in accordance
with the appropriate regulation.
As a guide, the BS5440 series of British Standards
deals with this issue and currently states that an air
intake must be at a minimum distance of 300mm from a
gas boiler balanced flue. Installers are advised to be
aware of the requirements of this standard when
installing ‘through the wall’ supply air ducting.
Similarly, supply and extract air grilles should be
at least 300mm apart.
