where the front sides of the steel box meets the masonry bricks there's like a 1/2 gap there. at some time there was mortar in there to seal it, but over the years it's cracked and fallen out.
any suggestions as to how to permanently seal that gap? i'm looking at a friend's fireplace and I thought about using high temp mortar but he said he's tried that in the past and it eventually breaks away.
maybe weld a piece of metal to overlap the gap?
any suggestions?
it would be the areas in red but INSIDE behind the brick front:
