purchased the 50 inch recessed wall mounted fireplace and just love it. But after a day I noticed a ticking noise about every 8 seconds which drove me crazy. So I took it apart and found that the flame petals that turn were hitting on the side of the frame so did a little adjustment to the shat that turns and it is perfect now. Some thing like this should have been caught on the final inspection most people would not be able to take the unit apart. other than that I love the look and performance. Thanks Ron
