Which way is open on fireplace damper handle?

The positioning of a fireplace damper handle is contingent upon the damper's type and design. In numerous instances.

When the fire valve handle is parallel to the chimney, it typically indicates that the damper is open. This position allows for proper ventilation and the release of smoke.

When the handle is perpendicular to the chimney, it generally indicates that the damper is closed. This position helps prevent heat loss when the fireplace is not in use and keeps outside air from entering the home.

However, it's important to note that the specific configuration can vary based on the damper design and installation. Some dampers may have a different mechanism or markings to indicate the open or closed position. If you are unsure about the operation of your fireplace damper, it's recommended to consult the manufacturer's instructions or seek assistance from a professional.
