Using your Christopher Knight Home® Outdoor Patio Concrete Fire Pit is a breeze. Since it's fully assembled, you can just place it where you want in your outdoor area. Connect the gas supply to the concealed fuel tank, turn on the gas, and use the adjustable flame feature to set the flame size as you like. For safety, always place the fire pit on a flat, stable, and non - flammable surface. Keep it away from anything that can catch fire, like dry leaves or curtains. When you're done using it, turn off the gas supply. To maintain it, clean the fire pit regularly with a soft brush to remove ashes and debris. You can use a mild soap and water solution to clean the exterior, but make sure it's completely dry before using it again. If you're not using it for a long time, cover it to protect it from the elements.
