height of transition to anchor plate Starting to cut some of my transition bricks to go from the brick vent opening to the anchor plate. I have a 6" pipe and a 36 inch internal sized oven. I am wondering about the height of transition area to anchor plate. I see Ken has quite a large space in there and others are shorter. Is there an ideal number? Mine will be about only 4 inches from top of arch vent to anchor plate and then I have 3 feet of pipe for my chimney. Does this sound OK? I choose 4 inches as it will make the job easy but I can make it higher if necessary....thanks wayne |
