I put in a Desa VC42 fireplace several years ago until I get the dough to put in a real one. The glass doors I got with it were just plain cheap as hell, so I took them back. It was 4 panels and there was a big gap between each panel of glass. I'm looking to put some glass doors on it that will seal a little better so that when I get up in the morning, I've still got enough heat left to throw some more wood on. With it just open right now, all I'm left with is ashes. Does Desa make decent doors for this thing, or can I put a generic door assembly on it that says "Not for manufactured fireplaces". I'm sure this is for liability reasons. Is there any reason why they would be a problem?
