yes, there is.

It looks like this and provides both the exhaust and the air inlet.

Thank you!!

Jake have you installed this? Do you have any pictures of what that looks like on the exterior of a house?

Thanks. Gosh that looks great!!!
Apparently we cannot use this system because our heater is dual pipe system💁‍♀️. I’m being told they cannot cut the pipe down and basically we are stuck with this eyesore. Any suggestions would be greatly appreciated

Well, my husband actually found a YouTube video showing how to trim the system so that only the black portions are visible which are apparently UV protected and paintable! Sending that off to our GC now. Fingers crossed

They are using a concentric vent termination.

They COULD have used this type instead - but they have a 3" hole in the wall now.
