This is my first home with a gas insert fire place.
As far as what mount, I have just begun looking into them and certainly am open to suggestions from you all.
When dealing with a fabricated fireplace, I would remove one brick at a minimum, or a few so I could install a back box, then drill a hole in the substrate and use a camera to see what's behind.
Measure to find studs and then use long screws to go into the substrate. Nothing will let go ever.
