Flue options

The Greenstar CDi Classic System
RSF (60/100 telescopic, 60/100 longer telescopic and 80/125
telescopic) flue systems and two vertical RSF (60/100 or 80/125)
regular flue systems:
The systems have different maximum flue lengths for different boiler
outputs and different plume management lengths.
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.
For example on a 30CDi Classic System
effective length was 1500mm, the inner flue would be reduced to
5200mm.
