Gas fireplace how to seal

+4
Answered
Have a gas fireplace and there are about 1 inch gaps all along the fireplace to the brick - see photo. I have some fire grade caulk sealant but the gap is a little too large to just use that. Any suggestions on how to seal the gap? The metal does get quite hot when the fireplace is on. Thanks in advance.
