Hi, I have a Vermont Encore wood stove and recently replaced the catalytic element. The throat hood covering the cat entrance came off easily but it will just not go back on, after many hours wrestling with it I am at my wits end! I remember having similar struggles a few years back but nothing like this. Anyone familiar with this stove have any thoughts or suggestions? The problem seems to be the little knubs near the pins keep catching the vertical metal protrusions on the fireback preventing me from sliding the darn thing in. Maybe just try to file some of that metal away? Any help is greatly appreciated!!
