Nice hood. I expect that it uses a remote fan. I have a semi remote fan (not totally at the end outside, but mid way along the duct). Cuts down on noise considerably.
I would use the end pates if there's an option.
[edit:] I just measured my Wolf range height and it's 36". 32" seems low to me. That's the typical height of bathroom vanities; kitchen counters and counter height appliances are typically 36".
