Gas fireplace insert too small
Hello: We recently had a vented gas fireplace insert installed in our wood burning fireplace. The problem is that the unit is too small and there is about a 3/4 inch gap at the top between the unit and the brick. The gap isn't as long as the insert, it's kind of centered right at the top.
The installer tried an extension kit, which won't work because the gap is not the length of the entire unit.
Has anyone had this problem, or can anyone offer suggestions?
I think it needs to be returned and the right size installed. For some reason the store we bought it from is insistent on fixing this problem instead of replacing it.
I can't come up with a solution short of refacing the entire fireplace and decreasing the opening size.
This is frustrating.
