Condensfit II™ telescopic flue and plume management
system measuring
The maximum effective 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.
External plume management bends still need to be allowed
for. See below.
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 34.
The effective flue length can be determined by adding
together all the straight flue lengths and the effective
lengths of the bends used, 2,000mm for each 90º bend
and 1,000mm for each 45º bend.
