Plume management system
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 26.

For every extra 1,000mm of plume management after the first 500mm,
the internal 60/100 flue length must be reduced by 700mm, up to a
maximum of 4,500mm of plume management.
