The first one I bought flared outside the flame cage when set on high. When I complained, I was sent a brand new one right away. No questions asked. However the replacement was even worse. Its ok when set at about 75% but cannot be set on high because it then becomes a fire hazard because it flares so badly. 75% does not give you much heat---certainly not 45,000 btu's. I will not return this one because its better than nothing and I can't be bothered to put another one together. I would definitely not buy this product again. The service at Wayfair is absolutely excellent. The product---that's a different story!
