6. BLOWER TO 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 NOT align well, then flexible
METAL ducting can be used to adapt to an offset.
Good alignment without use of flexible ducting is best.
