Can the intake pipe and exahaust pipe be the same on the Amana Air Command 90% efficiency furnace?

Here is the link to the Amana 80-90% AFUE installation guide. On page 50 it begins to cover venting. Based on the charts I saw, it appears there is an intake and a flue (two separate pipes). If you're still unsure, I would recommend contacting your contractor about the installation.
