Regardless of whether the campfire is lit or not, the dinosaur chops above it will still be cooked.
No matter how far apart the campfire and dinosaur chops are, as long as the dinosaur chops are directly above the campfire and there are no blocks blocking them in the middle, they will still be cooked, even if they are hundreds of meters apart.
