What are these handles on this wood stove for?

Do any of you know what these handles are for on the front of this wood stove? The manufacturer’s label was not accessible. I tried actuating them from right to left while looking inside the stove right behind that, but nothing appeared to be happening.
It looked like some kind of handles may have been missing.

Also, looking straight up from the inside of the stove, the chimney pipe appeared to be dampered somehow, but I could not actuate it.

Without manufacturing data and model number, I suspect, combustion air and warm air circulation vents.
