[] BLOWERTO DUCTWORK ALIGNMENT
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 NOTalign
well, then flexible METAL ducting can be used to adept 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.
