Hi all,

I'm in a home with a fireplace for the first time and I noticed that
the flue lever has notches cut into it that would allow it to be
partially open. It would seem to me that a flue should always be
completely open when the fireplace is in use and completely closed
when it is not, but it would appear there is something I'm missing.

I've seen this on other flue levers as well. Is there a better way to
use a flue when operating a fireplace?
