so I have a progress hybrid sitting in my garage and a mason coming to install stone over my existing brick fireplace and after a lot of measuring I realized that with my hearth pad being 1.5”, the exit flue is going to be about 2.25” too high to fit through my fireplace! I don’t want to use the short legs and I’m set on the ash pan. I’ve read a lot of forum posts on raising the lintel. My mason is coming tomorrow to look at what we’re dealing with but I’d like to get your advice as well. I’m posting some pictures so you can see but basically I think the lintel is the piece of angle iron right under the first course of bricks. Then there is the flue. Will it be possible to raise the lintel 3 inches? Is it going to be really expensive to do? Any advice or tips would be greatly appreciated.
