I finally installed a key damper on my Lopi Freedom, I think it will be the only way to get good control of the fire and a long burn time without smoldering the fire. I installed it through the appliance adapter and the heavy wall liner. I blocked off the hole in the center of the damper for more reduction, flue is 29'. Here is a few pic I still have to put the trim piece now I need a cold night or two to test it.
