The left side tubes blow much hotter air than the right, it seems to split right down the middle. Has anyone else with this stove noticed this? or any other stove for that matter? This happens at at any setting, the right side will get hotter but always stay substantially cooler than the left side. There is nothing separating the left and right side tubes on the inside or outside. Using 3 inch Simpson Duravent with 4 ' of vertical rise on the outside. Using Fresh outdoor air I have checked the door and ash pan gaskets, and with an uneducated eye they seem fine. This stove is brand new and has been running for about a week. Burning LGs Thanks in advance to anyone with any insight.
