If an exhaust plenum and exhaust ductwork are desired, how does the exhaust ductwork attach to the vertical section plenums and what are the guidelines for the exhaust ductwork?

Typically, the exhaust duct attaches to the left side of the plenum on the left side of the lineup (looking from the front of the lineup) or to the right side of the plenum on the right side of the lineup.

Additionally, the typical configuration has the exhaust ductwork running in a straight line (no bends) to where it exits the building. Although what is described above is the typical exhaust ductwork design configuration, it isn't the only alternative. The exhaust ductwork can attach to the front or rear of any section in the lineup (normally it would be one of the end sections) and the exhaust ductwork can run to the front or rear of the lineup. This design isn't the standard and will need to be reviewed and approved as a custom configuration. As stated above, typically the exhaust ductwork runs in a straight line from where it attaches to the vertical section plenum to where it exists the building, but the exhaust ductwork can have 90 degree bends. There is no limit on the number of 90 degree bends but they should be kept to a minimum. The first section of exhaust ductwork that attaches to the section plenum can have a 90 degree bend but the exhaust ductwork section must extend at least 2 meters past the edge of the vertical section.
