Wow -- what a disappointment. We received this fireplace and assembled it about 40 days ago. It worked fine for the first 36 days. Now, if you turn it on, the heater runs for about two minutes before the heater shuts off, the unit starts beeping, and all the lights on the unit start flashing. You have to unplug it to stop the beeping. I'm reaching out to Wayfair to determine whether they will repair or replace it, but I am so disappointed. No product that costs over $500 should fail after a month of use. Buyer beware.
