How Do I Close My Chimney Damper?

Close the damper to a fireplace by ensuring the fire is out, locating the lever controlling the damper and pulling the lever toward you. Some models require pushing the damper to disengage it before pulling it forward. Keep the damper closed to prevent heat loss.

  1. Extinguish the fire

    Regardless of the type of fuel used in the fireplace, the fire should be out, and the firebox of the fireplace should be cool before attempting to close the damper. Stop adding wood several hours before you plan to close the damper, and allow the fire to die naturally. Closing the damper when the fireplace is still warm directs any remaining smoke into the living area.

  2. Locate the lever

    Look inside the firebox for a lever that controls the damper. The location varies, but the lever is usually toward the front. Some fireplaces use a set of chains or a knob outside the firebox instead of the lever.

  3. Pull the lever

    Put on work gloves to keep soot off your hands. Push the lever toward the back of the fireplace to disengage the damper, if necessary, and then pull the lever toward the front of the fireplace. Keep the damper closed when you are not using the fireplace to minimize heat loss.
