    Make sure the type you buy uses a fusible link, rated at 160f for example. When the rated temp (of the heating air) is met the solder fused link melts, the link breaks into 2 pieces and the fire damper, gravity and/or spring driven, will slam shut.

    Melted link on the right, good link on the left.
