Hearthstone 2 rebuild

[Charlie15]

Hello everyone, hoping that someone here can help me out. I have what I believe is a 1981 Hearthstone 2.
Probably looking to restore it at some point this summer. The laundry list of issues I’ve been having with it is growing. Overfiring being the number 1 issue and I haven’t been able to narrow down the main air problem.

I feel as though it could be the lack of cement between the soap stone itself. All the doors seal nicely.

Can anyone recommend someone that would rebuild it for me or potentially do it myself. My biggest fear is having to replace the stone or not put it back together correctly.

Yes i realize the hearth is not the right size we purchased the house with the stove

Hi Charlie, and welcome to the site. I know this is not the answer to the questions you asked, but your main issue does not look to me to be overfiring. Your main issues are the clearances to combustibles and the undersized hearth. If you can't get those worked out to fit this stove, then you really need to look for something else that fits in the space you have.

Pictures can be deceiving, so I might be wrong about your clearances. I just want to urge you to check the clearances against what they are supposed to be. Keep in mind that if there is a stone veneer on the wall behind the stove, the clearances are to whatever is behind that veneer. A veneer attached directly to a combustible wall does not gain you much when it comes to stove clearances. Also keep in mind that a 36" clearance means 36" not just horizontal but at any angle. I always look at it this way: if I can take a 36" long stick and touch both the stove and a combustible at the same time (at any angle in 3D space) then a 36" clearance is not met.

Do you have the manual for your specific stove? I found this sheet just Googling for the manual....

Also, I had one of these stoves for a few years. I liked it, and it was pretty. Moving on from that stove was the right thing for me to do and I never regretted it.

To address your original question, it has been almost 20 years since I had my Hearthstone II, but I do remember having to remove stones. I had to replace the baffle and shielding plates inside, so I believe I took the top stones off.

I broke hardware doing it. I had to cut or drill some screws. I do remember using refractory cement of some kind when I replaced the stones but I can guarantee that I did not know what I was doing. I also think the stones had grooves milled in them at the seams between them with metal strips in the grooves.

I would not want to do it again. Everyone has preferences. My preference now is a quality welded steel stove over one that is made up of bits held together by hardware and glue.

Have you run the stove in the dark and observed all the joints between the stones and between the stones and cast iron? You might be able to see leaks.

You can also use an incense stick or "punk" as a smoke source, run the stove, and try to find seams/gaps where the smoke gets sucked in. That could tell you where you need to focus your efforts. Maybe your doors leak terribly but the stone seams are just fine.

Yes, I do realize the clearances are not correct. We bought the house with it like this an I haven't had time to replace the hearth or move the stove away from the wall. The previous homeowner left the house a mess so this has been much of an after thought until now.

I have used an incense stick and found the ash pan leaked quite a bit, the 3/8" gasket seamed way too big for it and would not completely seat around the opening when closed. (Hinge style door w/ camlock) I replaced it with a smaller gasket and that seemed to do the trick.

I am really not an expert on wood stoves so most of this is all foreign to me. The secondary burn tube seems like it needs to have cement around it, between the pipe and soap stone there is a big gap just letting air through.

Right now I have an abundance of silver maple i have been using to burn with, temperature is more controllable with the ash pan fixed but I am just chewing through wood. I typically put 3-4 good sized logs in and it maybe will last 2 hours before i need to reload. Tons of coals in the bottom but I have heard these stoves don't typically need to be reloaded that often.

When rebuilding, get a tube or two of Hearthstone's refractory stove cement.

Thread '1985 Hearthstone II rebuild'

May 2, 2015

I Recently picked up another Hearthstone II ala cheap. It is a 1985 model year, and the ultra rare right hand door model (only about 30% were RHD). The stone was beautiful; but of course, all were cracked. It will get a whole new set of stone. The inside was completely burnt up, so everything inside will be replaced as well.

The day I took it home:



Inside was bad:


It has a coal grate shaker, which I am going to remove. There is no use for it, so its gone...



5/3 - I grabbed some Sam Adams Boston lager, and started the tear down...
