External Face-and-Bypass Connections
The external face-and-bypass damper sections will
require a field-fabricated duct to direct the bypass air into
the appropriate section. Duct sizing recommendations are
listed in Table 34.
When attaching a bypass duct to a downstream fan section
or access section, the section will have a factory-provided
opening. (see Figure 128, Figure 129, and Figure 130.)
When bypassing into an access section, remove a panel. It
is not necessary to cut an opening.
