  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.

      I would have figured the exhaust would be hot enough to melt the plastic. My understanding was that you have to have metal for the first X feet because that’s what would be where it’s hottest.

      But what do I know? If they say you can use plastic from the beginning then have at it. It’s cheaper and easier.

  Nice work! Is there a reason for not connecting the exhaust back to the chimney like before?

    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.

    Haha thanks, it was the best way I could find to support the PVC, otherwise it would’ve been kind of a long run
