Bosch Nexxt Series Instruction Manual page 14

All joints should be tight to avoid leaks.
The male end of each duct section
must point away from the dryer.
Whether connecting to an existing
venting system or a new venting
system, make sure that all ducting is
clean and free of lint.
The maximum permitted length for
rigid duct and for rigid duct used with
flexible metal duct is shown in the table
below. If using flexible metal ducting to
connect the appliance to the ductwork
system, the total length of flexible
metal duct used shall not exceed 2.4 m
and can only be used to connect the
dryer to the ductwork system. As the
table below shows, the maximum
overall ductwork length is reduced if
flexible ducting is used.

Note:
Side and bottom exhaust installations
have a 90 °turn inside the dryer. Take
this into account when using the table
above.
More than two 90 ° turns are not
recommended. For best performance,
separate all turns by at least 4 ft. of
straight duct, including distance
between last turn and exhaust hood.
