Helllo. I've been reading and reading this forum for some time and now I've got a question or questions about a stove I just bought. It's a Jotul 3TD 1987 with black blue enamel that I got from CL for $225. Just the bottom burn plate needed to be replaced along with gaskets. What I don't know about is: The side burn plates have a flat top and a groove on the bottom- what I don't know is if the flat part is oriented up wards or if it fits in the bottom burn plate groove. Do all the plates inside get cemented together or are they suppose to be left loose? Is there suppose to be firebrick? and is the door suppose to close tightly and if so how do you tighten up the door latch. Sorry If I sound like a dummy. This is my first woodstove, for my first house. And maybe if there's anything else I should know about this stove that'd be great. My house is 560sq ft-of which 400 is wide open with a 1/2 story of 200 sq ft and an unfinished-but insulated basement, I think this will heat my home. When I was looking at woodstoves just a few days ago, the dealer said I need a 1600 to 2200 sq ft stove to heat my house. I don't know if he was telling me the truth, or just trying to sell me a more expensive stove. When I saw the Jotul on CL I knew this would be a cheaper experiment as to what size stove I needed.
