Hello all, I am in the middle of restoring an original defiant encore. I see in the bottom unit (ash drop) of the stove right above where the ash door bolts to the stove there is a hole about 7/16 in diameter and another directly across the lower unit. Are these supposed to be here?? Or did someone at some point do this?? It is an air tight stove and these holes would let air in. Am I missing something that should be mounted in these holes? Looking at the parts list for the stove I don't think so. Anyone know what I'm talking about or have one of these stoves they could look at? This one is a model 0028 1986. Any help would be greatly appreciated. Thanks
