Greenstar Ri regular boilers are able to use the maximum
100mm dia. internal flue length of 4,600mm regardless of
the amount of plume management selected.
External plume management bends still need to be allowed
for. See below.
For Greenstar CDi Classic Regular boilers the 100mm dia.
internal flue length must be reduced by 700mm for every
additional 1,000mm of plume management, refer to table
and graph 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 pages 34-35.
Use the graph below to determine the permissible plume
management length that can be used with your effective
flue length ‘L’.
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.
