  • Down is a common position for closed, but not always. For something like an air vent, can usually try in both positions to either look and see, or feel if the air flow changes. Looking in the manual(maybe online) is good also.

  • Stick your head in the fireplace.
  • Shine a flashlight up the chimney.
  • Have a helper move the lever.
  • You should have no problem seeing the damper move
    • When it's closed, you yell to your helper "It's closed!".
    • Make sure helper stops moving the lever at that point.

You can then look at the lever position and make a label indicating the closed position.

Important Notes:

  1. Make sure there is no fire burning when you're doing this, you're not Harry Potter.
  2. Eye protection is recommended as moving the damper will possibly dislodge crud that you don't want in your eyes.
    1. Consider a face shield, as you probably don't want to come out of the process looking like Bert
