Discharge Plenum Connections
Discharge plenum sections are available with or without
openings. Sections with rectangular and round openings
have a framed opening that can be used to secure the duct
to the frames. If the duct is lined, it is important the
insulation does not obstruct the opening of the section.
For a discharge plenum with field-cut openings, attach the
duct to the side panel.
