7.1 Position of the opening of a fan-assisted flue gas guiding
Key:
(1)
There should be no ventilation/opening in the eaves within
600mm distance of the terminal.
(2)
These dimensions comply with the building regulations, but they
may need to be increased to avoid wall staining and nuisance
fron pluming depending on site conditions.
(3)
It is recommended that an elbow termination is fitted to direct
the plume away from windows.
(4)
If the pipe is shielded from the heat this dimension may be
reduced to 25mm.
(5)
The flue through the roof should not be located within the
shaded area.
(6)
Is is recommended that the terminal should not be located
below 2m in any occupied space.
BS 5440–1: It is recommended that the fanned flue terminal
should be positioned as follows:
– at least 2 m from an opening in the building directly
opposite, and
– so that the products of combustion are not discharged
directly across a property boundary.
– 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 vapour plume does not dam-
age adjacent surfaces, the terminal should be extended
as shown in ¬fig.7.3.
– Dimension H:
This clearance may be reduced to 25mm without
adversely affecting the performance of the boiler. How-
ever, in order to ensure that the condensate vapour
plume does not damage adjacent surfaces, a clearance
of 300mm is preferred.
For IE, recommendations are given in the current issue
of the IS 813.
