Came here to say this. We have parrots so we have to be very careful about things like this. When we got a new range, we hooked it up in our work building in an area with roll up doors and ran the oven and stove top on their highest settings for a few hours several days in a row. Then we cleaned everything with vinegar/water before installing it at home. I'm not sure how you could do this with a wall oven but it worked for us and our birds did just fine :).
