FLUE OPTIONS

ErP
The Greenstar CDi Classic has the option of three horizontal 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.
ErP
For example on a 29CDi Classic
length was 1500mm, the internal flue would be reduced to 5200mm.
