Flame is good could be a little rich has a slight turquoise look at the beginning of the flame. I am at sea level. The noise (higher frequency oscillation are and constant tone) seem to be coming from the control box. I am almost deaf is some frequencies due to working in power plants and combustion turbines. I will know more when the little lady gets home from work.
I did determine that it is cutting off before reaching temperature but it will run for probably at least 5 minutes or more.
I am in the process of fixing the three skylights today. Two down and one to go. The outer lite was broken on all three. So I am taking it all apart and replacing both outer and inner plastic. Lexan on the top and acrylic underneath.
