Using your Christopher Knight Home® 32 - inch Grey - Top Stone Square Fire Pit is a breeze. First, make sure the fire pit is on a flat and stable surface outdoors. It's fully assembled, so all you need to do is add the included lava rocks to the pit, but don't cover the burner. Then, connect a standard - size propane tank to the built - in tank space. Once everything is connected, you can ignite the flames and enjoy the warmth. When it comes to safety, always keep a safe distance from the fire pit, especially if there are kids or pets around. Don't use the fire pit in windy conditions to avoid flare - ups. For maintenance, after each use, let the fire pit cool down completely. You can use a soft brush to clean off any debris or ash. Also, check the propane connections regularly to ensure they are tight and there are no leaks. With proper use and care, your fire pit will provide many years of enjoyment.
