Hi y'all doing everybody! hope everybody is warm. I have a Jotul 3CB which I'm replacing with a used Jotul F400. I've been looking for a larger stove due to the burn time and when the temps drop below 28° my little stove has a hard time keeping me warm. I have found a used F400 which I hope to PU this weekend. Other than cracks and warping, is there anything else I should be looking for? I also came across a thread someone posted on a rebuild for the F400 on another forum. The stove I'm considering is 14-15 years old. I'm not sure how much use it got but from the pics but it looks like it is pretty good condition. In the post for the rebuild there were a lot more gaskets than for the door, ash pan and rear flue attachment than I thought there would be. Considering this stove may be in very good shape just being used as needed and not as a main heat source, how often if ever do the other gaskets need replacement?
