3.7 FLUE OPTIONS
The Greenstar CDi 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.
For example on a 30CDi if the plume management effective length was
1500mm, the internal flue would be reduced to 5200mm.
This page and the page opposite shows various flue options with the
straight flue lengths required to achieve the maximum flue length.
