Here's the vent Larry's installing. CLICK it to BUY it now.

The intake vent needs to exit through the rim joist, so it's about 8" from bottom of intake hood to ground. I plan on a little excavation/clearing and lining a small area with hard-surface (brick or whatever) under the vent. Do you have any thoughts on intake vent height and what else to look out for?"

Here's my answer:

I'd just make sure you check the exterior hood frequently. You don't want leaves or other debris to block it. With it so close to the ground, it doesn't take much to have a blockage.

You'll love the fresh air and you'll be much safer now!
