1) In addition, the terminal should not be nearer
than 150mm to an opening in the building fabric
formed for the purpose of accommodating a built-in
element such as a window.
2) Dimension B,C and D; 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 7.4.
3) Dimension F; 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.
4) BS 5440-1 It is recommended that a fanned flue
terminal should be positioned as follows:
a) at least 2m from an opening in a building directly
opposite, and
b) so that the products of combustion are not
directly directed to discharge across a boundary.
For IE, recommendations are given in the current
edition of IS 813.
