I upgraded to a Mansfield at the begining of this heating season. We LOVE it! Here are a few things that we have found out:
1. We LOVE it

Oh..... I said that already, but we really do. Coming from a steel stove, I will never go back!
2. Get an IR thermometer! ($29.99 at Autozone) Don't trust the Rutland stove top unit. I had been "Cruising at 450-500" and it was doing good. Bought an IR thermometer and found out that we were really cruising at 350-400. Now that I know the real temp, we are getting REAL heat. We bought it knowing that it would heat 2500 sq' at best, and my home is slightly over 3000 sq'. We bought it to reduce our heating bill, but we have only had to run the gas heat a few times (once or twice a week) if we are away for a long time. This stove has no buisness heating what I am asking it to do, but it does fine, and I hsve only been over 550 a few times.
3. Get it hot, and then shut it down. We can load at around 300 and shut it down at or before 400 and it will climb from there.
4. Don't be afraid of the 'SoapStone Worries" Somehow, someway this stove controls itself. I have never been over 600. It will climb.... make you scared...... more scared.... and just when you thing you are going to have to break out the fans, it calms down. Then it hangs there for hours! Great heat for a long time.
5. Let it run it's cycle..... Especially if you have wood that is not as seasoned as it should be. Get it up to temp, let it run, and when it drops below 450, increase the air, or just let it go for a while. If you reload to soon, you will find out that you will build up coals to quickly. Let her do her thing. If you have perfect wood, then this is a non issue..
6. Ash pan..... Gay as a French Horn.. Don't use it. You will try, and I know you will... But give up on it. I won't say it sucks, but it is not worth the effort. Sorry about the gay comment..... But it is gay'r than a cucumber sandwich. Trust me! Not that I am gay....
7. Stones will scratch.... So go easy if you use a stove top thermo. If you slide it on the stones, they will scratch. I have read that there are ways to take the scratches out, but I have never tried. I'm sure it's no big deal, just a heads up.
8. Load it as high as possible. As in full to the top. Don't be affraid. It will run best that way. Second air kicks in quicker and you can enjoy a cold beer quicker. I let her runs full for about 5 min, shift to 1/2 air and I shut it down before 10 min. Second air kicks in weak, but in 5min it is going crazy. Again, let the stove do the work if you have good wood. If you don't have good wood.... fine, but you will have to fuss with it more. It will still eat the wood as long as it is not green as grass.
9. Once it is in place, don't try to move it..................... Heavy
10. Enjoy!
