A:Answer Hello there, thank you for your question about the MVEL2137F model. For proper installation of the mounting bracket, a clearance of at least 30 inches from the bottom of the shelf above the unit to the bottom of the mounting bracket is recommended. Additionally, it’s important to account for the height difference between the back and front of the unit; the back is typically taller to allow for optimal ventilation. If you have any further questions or need additional assistance, please feel free to send us a private message on social media @LGUSSupport, and our team will be happy to help. We appreciate your time! —Avril
