Using your Christopher Knight Home® Outdoor Rectangular Fire Pit is a breeze. First, make sure you have a propane gas tank and connect it to the burner through the tank holder. Turn on the gas supply, and then use a long - reach lighter to ignite the burner. Adjust the flame as needed to get the right amount of heat. When using the fire pit, always place it on a flat, non - flammable surface and keep it away from any flammable objects. Never leave the fire unattended. For maintenance, after each use, let the fire pit cool down completely. You can use a soft cloth to wipe away any dirt or debris. If there's rust, gently sand it off and apply a fresh coat of powder - coating paint. Also, store the fire pit in a dry place when not in use to prevent damage from the elements.
