I'm having trouble figuring out exactly which model defiant I have. Also, I bought this stove off craigslist and the guy removed the doors to make the stove "lighter". I should have known something was up, but I didn't and one of the hinges for the door pins is broken. Are replacement doors even an option, or should I just try to have it repaired? I've attached a picture of the label on the back of the stove. There is nothing printed on the fireback inside the stove, but it is a 2 piece.
