FLUE OPTIONS
The Greenstar CDi Classic
ErP
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 29CDi Classic
ErP
if the plume management effective
length was 1500mm, the internal flue would be reduced to 5200mm.
This page and the next page show various flue options with the maximum
straight flue lengths allowed to remain within the maximum flue length.
