component parts. Units specified on a single order are shipped
with most components assembled in the specified airflow direc-
tion. When an upper component exceeds the 108-in. maximum

ponent parts also require assembly or adjustment; see the section
on each component type for specific instructions.

forth below is considered improper installation and abuse and
may not only negatively impact the weathertight performance
