Chipped porcelain on Jotul 507

Chipped porcelain on Jotul 507

PostBy: Daryl On: Mon Mar 05, 2012 5:34 pm

I have an opportunity to purchase a Jotul 507 coal stove. Condition is very good, except for several porcelain paint chips, some as large as a nickel. And, some rust rings on top due to the previous owner leaving a some wet cast iron cookware on it. And, a couple of scrapes along the side due to something abrasive sliding along the side. It's been stored in an unheated outbuilding and must have had lots of junk propped up alongside or put on top of it. Anyway, I'm assuming touch up paint will be no longer available (green), and that the rust rings may be permanent. Repainting may not be possible either, as doesn't this stove heat up to a much higher temperature than a woodstove? Engine paint will tolerate 600+, but this is well below the 800+ that this stove will run at, correct? Or, are there higher temp paints available? All being said, does anyone have any suggestions of how to deal (if it is possible) with the cosmetic condition of this fine old stove? Daryl

There are several brands of high temp paints. Stove Bright is what I use on my stove. Do an internet search for stove paint and the others will come up. For the rust, there are "rust eaters" at the auto store that will kill the rust. It turns black when you spray it on, then cover it with your stove paint. How much are they asking for the Jotul? Good luck, Lisa

The top cover is all porcelain, with a rust stain on top of it, which maybe has become a stain. Not sure. Spraying anything onto porcelain, in my experience, doesn't stick. Does stove bright come in a green enamel finish to match the jotul color?

Nah, you don't want to try and paint one of these girls. It's a surface you cannot duplicate. At this point in the stoves life, it's considered character. Some are in better shape than others. What are you paying for it?

I agree with Coalkirk. You don't want to try & paint it. A touch up here & there on chips, OK, but the whole thing or the whole top, it's not going to work so well.

Thanks for weighing in on this. We're still talking price. Seller is looking for 400, but it may be negotiable, especially with there being a few chips on it. The interior is excellent, meaning it probably hasn't seen a whole lot of use. I don't know whether this stove is a NR 507 or a NR 507B. How would I tell the difference? I have also seen some of these stoves with short legs, but this stove has the base which sits flush to the floor. Is this the difference between the 507 and 507B?

In addition to burning coal, I have a huge amount of kiln dried oak blocks from a cabinet factory, mostly 2" to 4" squares by 3/4" thick that I'd like to add to the coal fire, maybe 4 or 5 pieces at a time. With the coal fire being extremely hot, my theory is that the wood block would also burn quite cleanly. Any thoughts on this?

No matter how you slice it wood is still half gas and that gas to burn, needs air as well as heat. That's over fire air which will drive up stack temperature and at the same time act as a check to the under fire air that the coal needs.

Burn one or the other. The good part is that the wood is in small pieces so will fit the fire box.

The only difference in the 507 NR & the 507 B is the under fire air draft spinner on the ash door.
The stove will have the number and letters cast in the stove Just above the ash door by the shaker shaft.

Jotuls all have a chip or two....They heat very well and are the easiest stove to burn Anthracite I know of. ;)

Thanks for steering me straight on that. I haven't been around a coal burner since I was 10 years old, and that was quite a long time ago! So, I have to do some learning again about coal. We burned bituminous coal back in those days, but it was quite a dusty mess, so my parents preferred to burn wood instead. With the kiln dried oak pieces that I have, I do know they burn extremely hot, so I would expect they won't generate as much creosote as burning logs.

This brings to mind some related questions: With the 507 being a bottom burner when burning coal, is the flue temperature as high when burning coal as with wood? When burning wood, I have always used a clay liner/cinder block chimney. Is a metal chimney satisfactory to use for a coal stove?

hi daryl. i acquired a 507b with our house.. set it aside for a few years until an ice storm put it into service - had no clue, but got some heat. the 507b as a short arched base, spinner damper on bottom ash door, spinner damper on top/scuttle door for secondary air. my stove runs a hotter stack with wood, heats the casting faster. start adding blishack nut coal on top of your wood base. you will reduce primary/lower damper air. i have no hard and fast method for the secondary air, except to say that it should be open at least 1 turn, the rest depends on your draft situation. read up on puff back/explosions from opening a scuttle door without letting some secondary air mix first - very exciting, potentially very messy. we had the 507b running about 5 days on one light during christmas - my 14yr old kept it going... agree with the guys on the "character" of chips - the enamel changes color as it heats up, probably can't duplicate that out of a can. wipe up any retort cement right away. make sure the grate handle is included - need it to pull the ash pan. i can now fire for a weekend, or just an evening since i have it figured out. i enjoy firing with wood for a while before adding coal, but there is no benefit to adding wood to a coal fire. look for references to the blue ladies - very cool, but our lack is a window to watch them - i open the top dor a lot. enjoy!!

Jotul 507 owners manual

PostBy: Daryl On: Wed Mar 07, 2012 8:33 am

Thanks for all of the great tips about the 507. There is no substitute for having actual owner experiences to draw from. If I do end up with the stove, I know I'll have a pretty good jump on how to operate it properly. It would also probably be good to have a photocopy of the manual for this stove. By any chance, would anyone here have a copy, or a pdf file of one? I am more than happy to pay expenses as necessary for a copy.

LOL!! Best bargain in town. Thanks a ton! Will post some pics of the stove after getting it home. Last night, had a chance to look over some of the older posts about the 507 here on this forum. And, the pics, too. Also saw some other pics on the net showing short legs under some stoves. And, a smoke box on top. Wow.
From what I've read, the stack temp when burning coal is lower than when burning wood. So, efficiency when burning coal has to be quite a bit higher than when fueling with wood. Are there any efficiency numbers on this?
