Flue/Chimney Location

1. The following guidelines indicate the general requirements for
siting balanced flue terminals. For GB recommendations are
given in BS 5440 Pt 1. For IE recommendations are given in the
current edition of I.S. 813 "Domestic Gas Installations".
Under car ports we recommend the use of the plume
displacement kit.
The terminal position must ensure the safe and
nuisance - free dispersal of combustion products.
