Gas Fireplace Damper

Interesting place for a soup can.:smiley:

I have seen a firepalce damper similar to this but the soup can had been cut off already. Here is a link to the photo taken of it. you can see the ring left on the damper from the soup can. In this image the fireplace damper is a gas fireplace and it has the clip on it to keep the damper open.

I believe the soup can is a weight that is intended to keep the swivel type damper closed so downdraft winds in the fireplace chimney do not blow it open on accident.
