    Hello everyone!

    I bought a (Danish) Lange 6302A red porcelain coated, cast iron wood stove about 34 years ago, and still think it's the highest quality and most efficient wood stove I've ever seen. It went unused for a number of years due to a geographical move, but I now want to install it in my son's new house now. Before I do, I'd like to completely disassemble it, re-cement the panels and replace all the hardware. That brings up two questions:

    1) What do I use, standard boiler cement?

    2) What type of hardware (screws & nuts) do I use? Because Lange stopped exporting these fine stoves when the EPA started getting goofy back in the early '80s, I can't find any illustrated parts manuals, specs, or anything.

    Any help would be greatly appreciated!

    Thanks,

    Jim

    Use black furnace cement - Rutland black is my old favorite.

    It is possible to squeeze it into the seams from the inside if you don't want to take the stove apart. However, if you decide to rebuild totally, you can simply use regular metric bolts from the hardware store or McMaster-Carr for the replacements. If you want to step up a grade, you can use hardened bolts for the leg mounting, etc. but regular should do the job just fine also.

    You should be able to get enough of the old ones out to determine what the metric thread side is.

    Thanks Webbie & Begreen!

    Sorry to take so long to respond, but I'm recuperating from a brain aneurysm I suffered 10/10/13, and some days I have more ambition than others.

    I always loved this stove. I'm hoping I don't have trouble getting it apart without doing any damage, particularly since most parts are no longer available. I just want it to be in top shape for my son to start using.

    Woodman's won't know thread pitch I'm afraid, but it hardly matters. Simply replace nuts and bolts with common 3/8 hardware. Works every time for me!

    Jim, I'm glad you are recovering. I wouldn't tear it apart unless a rebuild is indicated. If it just needs liners or a baffle replacement I don't think it needs to be taken apart to do that.

    Hi again. Thanks for the good wishes Begreen.

    I decided to take it completely apart and re-cement it because of the age of the unit, years of use, and since I could see a couple very small spots that the cement was gone from the last time I burned it. I wanted my son to have the advantage of (functionally) a brand new stove with no worries regarding safety, as well as true airtight efficiency.

    Turns out the 4 bolts that hold this stove together don't take much of a beating!! They came out quite easily with a bit of PB Blaster, and looked fine for reuse, which surprised the Hell out of me! The other surprise I got was finding a floor plate to the stove, under which was a layer of some kind of fine particulate that looks more like cement dust than sand. Since I have no idea what it is, having completely disassembled, cleaned, and inspected the stove, we're going to put it right back under there before cementing it back together this weekend, unless someone has other info.

    I sure wish more parts were available for these stoves, for future reference.

    I wish they still made Lange stoves. These were well made, good heating and looking stoves.

    Resurrecting this old thread as I'm about to embark on the same project. I'm in almost the exact same situation... our old Lange has been sitting for years and I'd like to rebuild it before putting it back into service.

    Jim - did you wind up taking it apart? Did you use the black cement? Any pics?

    Regarding liners - Woodsmans wants close to $1000 for front, back and 2 side liners. Yikes. I'm not sure if I need new ones or not. Are there any other generic alternatives?

    You can use plastic refractory. Mold it flat and the size of the panel then seat it with a rubber hammer. 1/2" or so. One box is more than enough for most stoves.

    Sorry it took so long to respond.

    Yes, I took it completely apart and resealed it---wasn't hard at all---just a bit of a balancing act putting it back together. Definitely have someone there to help you and make sure you're putting all the parts back in the right places. I haven't seen seen reasonably priced spare parts anywhere, and don't need any yet, fortunately.

    Hey, I'm getting in on this because my beloved lange developed a big split in the upper plate that the damper slides in, whatever that's called. Haven't called woodmans yet, but I suspect my chances are slim that I'll find this part. Anyone have any thoughts on this?

    Do you mean the baffle? Got a picture of the problem?

    I don't, my camera is dead, but if you look at the blown up picture on woodmans, it's #10. It's cracked right down the middle starting at the damper opening, and sagging into the fire box which actually limits the amount of wood I can get in, as well as hurting it's performance. The stove owes me nothing, my buddy's dad gave it to me (there's a bit of sentimental attachment, but I'm trying to knock that stuff off). At the same time now, a friend has a defiant I could get for a couple hundred bucks, which I figure would be cheaper than replacing just about any part. I love the 6302, but I know lots of people love vt castings. Also, I'm guessing I'd have to change my pipe diameter from 6 to 8. Does that sound right?

    Yes, that's the baffle. You have a great stove. If the rest of the stove is in good running condition then it's worth investing in to keep it running right.
