the internal 60/100 flue length must be reduced by 700mm, up to a
maximum of 4,500mm of plume management.

NOTICE:
Plume management length:
▶ The plume management length must be a minimum of 500mm and
must not exceed the maximum straight length for a horizontal Ø 60/
100mm flue with a 60mm plume management system as stated
previously.
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 25.
