I'm building the 42" Pompeii and have the stand and hearth finished. I gave myself a few extra inches on each side for finishing with stone vaneer. I'm doing the layout now and looking at plans trying to figure out how far back the actual oven entrance is from the front apron of the hearth. It looks like it is over 2 feet. Any thoughts on oven setback???? I dont mind having some extra room at vent landing but it seems it might be harder to reach in with peel. ???
