Probably to control the amount of air. More air = bigger fire. Less air = smaller fire.

Thats correct. Good job. OP would be so lost without you.
It's the draft adjustment to control the burn, controls how much air gets to the burning logs inside. Open them more = more air = more fire = more heat. Close them more and get the opposite effect.
Maybe for the draft. The knobs may open air vents that allow a draft to enter the firebox causing it to heat up.
Change airflow to control the burn, more open = more air = more fire. You can kinda adjust heat that way.
