Hi Allen sorry it took so long to get back to you. It has a 6" hole in the bottom of the barrel and the other is White Chat, sorry about that. He has not watched the video yet, just looked at the forum. That may be the problem, the part of the house that we put the heater in is not finished, we use the room all the time but I know there is a hole in the ceiling and part of a wall that is not sealed off. Ok will look at the video and seal that wall off and see what happens. Thank you for all of your help I will let you know the outcome.
