OK so planning on installing my OAK soon. See pic below. The wall on the right has the inside of my garage on the other side. I have seen the combination exhaust / intake thimble before. Was thinking of drilling a hole in my existing thimble and running my OAK through there. Wondering how in that configuration you keep the OAK from sucking in exhaust? I guess my other option would be to run the OAK vent along the wall to the left until I get far enough away from my exhaust. Note that the bottom half of the wall is my foundation under the drywall. Any placement/install suggestions would be much appreciated!!
