    I’m not an HVAC guy but you can use PVC pipe in this situation??? That doesn’t seem right.

      It’s a high efficiency system. That’s what they call for. Instead of venting into the chimney they go directly outside, one is for intake of fresh air and the other is for exhaust.

      The new one is a high efficiency unit. So you don’t exhaust those through a chimney with duct, because they aren’t that hot, and they need an intake.
