I have found a Jotul 118 that was purchased in the late 70's, and according to the owner was used 5 or 6 times and hasn't been used since. He said it was left in the house as a decorator piece and from the pictures it looks to be true. I have a question about the burn plates. Are these something that have to be replaced often? They are expensive and I don't want to have to spend more to replace them a few years down the road than I paid for the stove.
