BS 5440–1 It is recommended that the fanned flue terminal
should be positioned as follows:
a) at least 2 m from an opening in the building directly
opposite, and
b) so that the products of combustion are not straightly
directed to discharge across a boundary.
1) Dimensions D, E, F and G:
These clearances may be reduced to 25 mm without
affecting the performance of the boiler. In order to
ensure that the condensate plume does not affect
adjacent surfaces the terminal should be extended as
shown in ¬ fig. 7.6.
2) Dimension H:
This clearance may be reduced to 25 mm without
affecting the performance of the boiler. However, in
order to ensure that the condensate plume does not
affect adjacent surfaces a clearance of 300 mm is
preferred. For IE, recommendations are given in the
current edition of IS 813.
For 1 and 2 above you can use the Variable Termination Kit
to move the termination point away from the building
fabric.
