I don’t really think that steam collecting on the chicken wire would be a problem. I think that I’m going to give it a try. Like I said, I don’t think the maple & oak leaves would go through the chicken wire. When the ash leaves were fall a few of them may have been a problem.
Baratone Brewer, PLEASE continue to use your fans and check your CO dector everytime you brew. I don’t have to much faith in them, I have seen to many of them not work properly. Before I retired and was still up on CO dectors Nighthawk make the best dector there was, I don’t know anymore. It sound like you are taking the right precautions, so keep it up.
