(1) By allowing cold air to flow in from underneath your fire, your fuel is going to burn hotter, brighter, and more efficiently. These high efficiency burns get the most out of your logs and leave you with a fine powder instead of chunks of charcoal. This airflow also acts to keep the fire pit relatively cool, allowing it to cool down in 90 seconds after you've extinguished your fire.
