Range Hood Makeup Air and Condensation

Does unconditioned make up air for a kitchen hood pose any condensation risk?
I’ve read this article and it makes sense. However, I was wondering if you’d ever get condensation around whatever is carrying the unconditioned air through the wall behind the stove?

Insulate the ductwork. There a lots of products that are available. You need a vapour retarder around the insulation. Not much insulation is used but if you find something that provides more insulation that less it is worth considering.
Always respect your building code.
