Smoke stack fully open?

Hey everyone I wanted to get some input on when I'm trying to maintain temps around 250 or so if I should leave the stack wide open regardless of what my firebox dampers are at or if my damper is partially open does that mean keep smoke stack partially open ? I've been cracking my firebox door with damper like a 1/4 open and stack fully open and noticed I can maintain temps around 275 .

Yes stack wide open. Control temp with firebox damper
