Can this be used on a deck on top of a glass table?

Hello Lisa, this appliance must always be used on a hard, level, non-combustible surface such as concrete, rock, or stone. It should never be used on wooden decks, combustible surfaces, grass, leaves, asphalt, or blacktop. The bottom of the fire bowl gets extremely hot during use, so it’s important not to modify the legs or place the fire pit on any object while it is burning. This appliance is intended for outdoor use only and should never be used indoors. Additionally, we recommend that customers check their local codes and regulations to determine the required distance the appliance must be kept from buildings or structures during operation.Should you need any additional information, please feel free to give us a call at 877-447-4768 or email at customerservice@ghpgroupinc.com. We appreciate your business and look forward to serving you in the future. Thank you! - GHP Group
