F_ BLOWERTO DUCTWORKALIGNMENT
In general, the use of flexible ducting is discouraged
because it can cause severelyrestricted airflow. However,
if the blower outlet and the floor or wall duct location do
NOTalign 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.
