3.7 FLUE OPTIONS
The flue systems have different maximum flue lengths:
The Greenstar series has the option of two horizontal 60/100 RSF
(telescopic and longer telescopic) and one horizontal 80/125 RSF
(telescopic) flue system and two vertical RSF (60/100 or 80/125) flue
systems:
The next page shows various fluing options.
Refer to the Flue options in table 7 for the straight flue lengths required

WARNING: Flue systems
▶ Only use Worcester, Bosch approved flue systems, no
other manufacturer’s flue systems have been
approved for use with Worcester appliances.
CAUTION: Non accessible flue systems:
▶ Where a flue system is not going to be accessible,
provision must be made for service and inspection.
▶ Voids containing concealed flues must have at least
one inspection hatch no less than 300mm square.
▶ Flue joints within the void must not be more than 1.5
metres from the edge of the inspection hatch.
▶ Inspection hatches should be located at changes of
direction.
▶ If this is not possible, bends should be viewable from
both directions.
NOTICE: Effective flue lengths:
▶ each 90° bend is equivalent to 2 metres of straight flue
▶ each 45° bend is equivalent to 1 metre of straight flue
