One is air control for sure the other may be outside air we really can't say without knowing the model of the fireplace. And honestly if it has been cut up it is no longer suitable for use in anyway.
thanks! the top stainless steel piece is thought to be a smoke deflector. did you see the knobs on the bottom of the picture as well?
i looked behind that gold grate at the bottom of the fireplace and it had a couple stickers on it, but i fear it just lists the chimney brand, not the firebox?
is there anything on these stickers to give me the manufacture of my fireplace?
any idea what this knob does? you can pull it out, but its on a spring that pulls it back in.
