Please take a look at these old gas grates:
Would there be any way to install something like a modern gas inserts in these fireplaces, but keep the decorative grilles? At one point these fireplaces burned wood so I am assuming there is some empty space behind the circa 1910 inserts. The chimneys were taken off long ago during various reroofing jobs, but since it's time for a new roof again perhaps new chimneys could be put up.
Thanks!
