    I think someone had a flying bug/insect problem.

    Or they were trying to reduce wind issues.

    Issues
    1. It's a flammable item on a heated exhaust.
    2. It could interfere with the opening and closing of the damper.
    3. There is a small hole in the side near where it is screwed on. This would allow bugs to enter.
