Comp No. 7212138 - 02 (06/14) EcoBlue Advance Combi 31
Before Installation 5
5.3.7 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”.
Due to the nature of the boiler a plume of water vapour
will be discharged from the flue. This should be taken
into account when siting the flue terminal.
