Ahhh... I did some skulking on the web, and see that in some communities
they will not allow you to close the damper on a fireplace anymore. I think
that this must be the case on the one fireplace. I bought the house in
December and they may have had to put this "clamp" on to prevent the damper
from closing.

While I was working on it, the clamp "fell off" (wink, wink), and now I
don't think I know how to put it back on again.

I think my flue not closing mystery has been solved.

I bought my house in December and am just now getting to poke around. I
have two fireplaces -- a smaller one with a rectangular flue and damper
that fully closes and appears to seal very well.

The larger fireplace (48"W x 32"H) has a round flue and damper that has a
threaded "adjustment rod" that will not let the damper close. As set
currently, it only allows the damper to be set at about a 45 degree angle.
I had a $140 natural gas bill last month (in Southern California) and am
thinking that I probably am trying to heat Palos Verdes with hot air
escaping out my flue.

Both fireplaces have glass doors that fit quite well, but I can feel the
draft from the flue on the larger fireplace when the damper is closed as
far as the adjustment rod permits (again, open it is at 90 degrees and
closed it is about 45 degrees).

The thing that puzzles me is that the rod does not look like it can be
adjusted down any more than its current position.

Any reason why the damper would be adjusted so it cannot close? (this is
my first experiences with owning fireplaces). I am thinking about just
removing the adjustment rod so that the flue can fully close, but I do not
want to violate code or cause a fire, etc.

best,
