7.1 Position of the termination in a fan-assisted air/flue gas
duct
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 and F:
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 pre-
ferred. For IE, recommendations are given in the cur-
rent 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 fab-
ric.
