Fig. 20 Plume terminal positions
NOTICE:
B All measurements are the minimum clearances required.
B Refer to previous page for all concentric flue terminal positions unless the flue position is specified on the figure above "Plume
terminal positions".
B Terminals must be positioned so to avoid combustion products entering the building.
B Support the flue at approximately one metre intervals and at a change of direction, use suitable brackets and fittings.
Key to illustration
1. This feature allows some basic plume re-direction options on a
standard telescopic horizontal flue terminal.
300mm minimum clearances to a opening e.g. window.
However the minimum clearances to an opening in the direction
that the plume management is facing, must be increased to
1,500mm. Where the flue is less than 150mm to a drainpipe and
plume re-direction is used the deflector should not be directed
towards the drainpipe.
2. 300mm adjacent to a boundary line.
3. Plume Management kit air intake can be reduced to 150mm
providing the flue exhaust outlet is no less than 300mm adjacent to
a boundary line.
4. 1,200mm between terminals facing each other.
5. 600mm distance to a boundary line, unless it will cause a nuisance.
BS 5440:Part 1 recommends that care is taken when siting
terminal in relation to boundary lines.
6. Using a Plume Management kit the air intake measurement can be
reduced to 150mm providing the flue exhaust outlet has a 300mm
clearance.
Plume kits running horizontally must have a 10° fall back to the
boiler for proper disposal of condensate.
For details on specific lengths see relevant boiler Technical &
Specification information.

7. Internal/external corners. The air intake clearance can be reduced
to 150mm providing the flue exhaust outlet has a 300mm
clearance.
8. Clearances no less than 200mm from the lowest point of the
balcony or overhang.
9. 1,200mm from an opening in a car port on the same wall e.g. door
or window leading into the dwelling.
10. 600mm distance to a surface facing a terminal, unless it will cause
a nuisance. BS 5440: Part 1 recommends that care is taken when
siting terminals in relation to surfaces facing a terminal.
Note:
B Installations in car ports are not recommended.
B The flue cannot be lower than 1,000mm from the top
of a light well due to the build up of combustion
products.
B Dimensions from a flue terminal to a fanned air inlet to
be determined by the ventilation equipment
manufacturer.
