How do you shut down fireplace at night to eliminate morning odors?

To shut down a fireplace at night and minimize morning odors, first ensure the fire is fully extinguished by allowing all logs and embers to burn down completely. Close the damper to prevent drafts and keep odors from entering the home. Additionally, consider placing a fireplace screen or glass doors to contain any residual smells. Lastly, regularly clean the fireplace and chimney to reduce lingering odors over time.
