I run the built in fan although its very noisy on high, and i also run a box fan blowing across the top of the stove trying to keep the top from overheating. Im concerned all this excess air causing overheating that its causing the door and stove body to warp further making the problem worse with each fire. The stove works ok with the first burn out of the box but get worse with each burn after that due to the gasket flattening and possibly the bow in the door and stove body getting worse with the high temps.
