You could seal the outside edge of the metal to the door using high temp RTV sealant that is designed for chimneys. It is rated for 500 degrees which is plenty for that unit (just don't use it on the inside).

Are you using the spray foam for just insulation? If so, you could get some fire rated fiberglass insulation to fill the void.

If it was me I would fill the void with insulation, seal the outside piece of metal, and let the inside seal itself with creosote/buildup over time. I don't like using any chemicals, sealants, etc in the actual cooking chamber.
