Greg, I haven't had any puffbacks, as you note the design really helps with that. My issue was being accustomed to burning well seasoned hardwood that responded to loading much more quickly than coal. That and taking eveyones advice to heart about running too fast creating clinkers and not giving the WM design enough credit for preventing backpuffs contributed to my frustration. I've developed a reasonably good "System" for reloading now, I have the BD dialed in to suit me, and I'm much happier with the stove. I still sorely miss the bimetal, and really need the extra capacity of the 400 to extend my productive time between loads, but I'm much happier now.

I sincerely appreciate everyones help. Without ya'll I would never have made the WM work.

ETA: JohnHenry, you have a PM.

Would like to revive this old thread. I just got a Warm morning 500 out of a barn and as soon as I figure out how to get pictures off my cell I will post some.

Stephen hopefully you are still on... what do you think the stove is pushing as far as BTUs go. I know it is a guess but compared to your other stoves and their ratings what is your best WAG.

The OP said he was loading 40 pounds at a time. So 80 pounds in 24 hours.

If the coal is 10,000 BTU per pound times 80 equals 800,000 divided by 24 equals 33,333 BTU potential output.

If your Alaska coal is less BTU, then output will go down or you can probably burn a higher quantity as well. I would think 100 pounds in 24 hours is possible.

The thinking behind the Warm Morning design is to have flame rising through the four chimneys to ignite gasses above the coal bed while supplying as little under fire air as possible in order to cook the gasses out of the coal bed slowly. The remaining coke is then easily controlled.
