Plume management system options
Standard plume management system
The flue terminal outlet has built-in stops to limit rotation
for horizontal fluing to allow condensate to run back into
the boiler for safe disposal. Do not attempt to force beyond
the limit stops.
All plume management sections must rise by at least
173mm per metre (10º) from the terminal to ensure that
condensate flows back into the boiler.

100mm dia. horizontal telescopic flue lengths with a
60mm dia. plume management system
The maximum effective straight flue lengths (L) are stated
opposite for the relevant appliance together with the
minimum and maximum lengths (M) of the plume
management system connected, these lengths must not
be exceeded.
60mm dia. plume management system
To ensure that the maximum total straight flue length along
the plume management route is not exceeded the following
should be added to dimension (M):
•
1,500mm for each extra 90º bend
•
750mm for each extra 45º bend
For plume management options with 60mm dia. extensions
refer to page 26.

System and Plume Management Kit, please see

Flue length ‘L’ versus plume management kit
Use the graph above to determine the permissible plume
management lengt
h that can be used with your effective
flue length ‘L’.
The effective flue length can be determined by adding
together all the straight flue lengths and the effective
lengths of the bends used, 1,500mm for each 90º bend and
750mm for each 45º bend.
