Cooking meat and pareve in the same oven

I cooked an open pan of chicken in an oven, and I  had a pan of vegetables that were cooking on the   rack right above it. What is the status of those  vegetables? Are they pareve? Are they considered   like they were cooked with meat, and they can't be  eaten with dairy? Do I even have to wait 6 hours   after eating them? It depends. If the chicken is  open, like we said, then the steam will go up and   will get absorbed into the bottom of the pan.  And then from there it gets absorbed into the   vegetables themselves. So, at the very least, we  view the vegetables as being what we call a nat   bar nat, a secondary taste of chicken, in which  case, one should not eat them with dairy. But,   there's a further issue. Which is that because an  oven is considered a closed box by many poskim,   therefore, the steam not only goes underneath  it, but it goes above it and back down into   the vegetables. In which case, the steam is not  just a nat bar nat, it's not just a secondary   taste through the wall of the pan, but it's like  it was cooked together with the steam itself.   Now that steam probably would be a very small  amount. Many poskim say you do not have to wait   6 hours after it. It's not considered that  it will give enough meat taste into your   item that it would require waiting 6 hours.  So, either way, one should not eat these   vegetables with dairy. But in terms of waiting  6 hours, one does not need to wait 6 hours.
