A:Answer Hi Mary! You can mount your TV over the fireplace; however, your primary concern will be the heat: Samsung TVs should never exceed 104 degrees Fahrenheit. Also keep in mind that if you mount your TV above the fireplace, it may be well above eye level when you're sitting down. Should you have additional questions, please reach out to Samsung Support at: 1-800-SAMSUNG (ask for TVs), available 8AM - 12AM EST, 7 days a week, or Chat with us on Samsung.com: https://www.samsung.com/us/support/contact/ ^Gina
