Plume management system
For every extra 1000mm of plume management after the first 500mm,
the internal 60/100 flue length must be reduced by 700mm, up to a
maximum of 4500mm 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°.
