Plume management system
The maximum flue length allowed for 0.5m of plume is 9m, each
additional 1m of plume reduces the flue length by 750mm, up to a
maximum of 4.5m of plume management with 6m of flue.

NOTICE
Plume management terminal:
▶ The plume management terminal must not be sited within 500mm of
the air intake, and must not exceed the maximum straight length for a
horizontal Ø 60/100mm flue with a 60mm plume management
system.
Horizontal plume management runs
▶ The initial horizontal run from the terminal elbow must have a
minimum 10° fall back, (stop tabs in the elbow prevent less than 10°)
to the appliance for proper disposal of condensate.
▶ Any further horizontal runs after an elbow can be 3°.
WARNING
Minimum plume management length:
The minimum distance of 500mm must be maintained between air inlet
and exhaust.
▶ Do not terminate the plume management inside the terminal
exclusion zone (shaded area) shown in figure 31.

NOTICE
Cutting the 500mm pipe
▶ The Plume management extension kit contains the components
required for such a configuration.
Plume management bends
NOTICE
Effective plume management lengths of bends:
Each bend used has an equivalent straight plume management length.
▶ Refer to the table 17.

CAUTION
Flue terminal positions
▶ All measurements are the minimum clearances required.
▶ Terminals must be positioned so to avoid combustion products
entering the building.
