Using your Modern Concrete Propane Fire Pit Table is a breeze. First, make sure you have a propane tank that's over 24 inches in height and connect it properly. Then, simply press the push - button ignition to start the fire. If you've bought the optional natural gas conversion kit, follow the instructions that come with it to convert the fire pit for natural gas use. Before using the fire pit, check that the lava rock filler is in place. You'll also need to add 20 lbs of fire glass for the best look. When using the fire pit, keep it on a flat and stable surface outdoors. Never leave the fire unattended, and make sure there are no flammable materials nearby. After each use, let the fire pit cool down completely. To maintain your fire pit, clean it regularly. Wipe the concrete surface with a damp cloth. If there's any debris in the fire bowl, remove it gently. This will keep your fire pit looking great and working well for a long time.
