5.3.1
Plume management length
Plume management length (M) is calculated from the centre of the
terminal, along the required route to the centre of the plume outlet.
Fig. 37 Plume management length M
Minimum plume extension length
The minimum extension length between two elbows/offsets is 140mm,
this allows for a good seal at the connection joints,
Also remember when fitting the extension tube into elbows/extension
fully into the outlet assembly [2], then withdraw the tube approximately
10mm to allow for expansion

5.3.2
Plume management elbows
Adding additional elbows to the standard plume management kit system
reduces the actual plume management length. Each elbow has an
equivalent straight length and must be factored into the overall effective
length.
• 90° elbow is equivalent to 1,500mm.
• 45° elbow is equivalent to 750mm.
