In general, the use of flexible ducting is discouraged because
it can cause severely restricted airflow . However, if the
blower outlet and the floor or wall duct location do NOT align
well, then flexible METAL ducting can be used to adapt to an
offset . Good alignment without use of flexible ducting is best .
NoTe:
• Do not exceed the maximum recommended offset of 6" .
• Do not allow the flexible ducting to kink or collapse .
• Do stretch the flexible ducting as much as possible to
eliminate as much of the corrugation as possible .
