It's completely manual. I'll wait till temps stabilize and then adjust the MPD. I had to close it to keep it at .05-.06.........
The bed is app. 8" deep......

This reminds me so much of when I was dialing in my Weber carb on my Samurai.....

Ok great.. The manometer will be a huge help in helping you with warm weather burns. I advise a barometric damper for more stable and consistent draft pressure.. :)

Let us know what adjustments you make to maintain the draft between -.03 and -.05 thru the day today. It will help paint the picture of your conditions so you can get more accurate advice. :up:

Through the day today as the chimney gases cool and at the same time the ambient temps outside increase, you will most likely need to rotate the manual damper open some to keep a good reading on the manometer...

Aside from the issues wind creates, the baro would assist here as well.....

Thanks so much for your advice. It certainly will shave off many hours in my learning journey....

The main problem with those stove designs that use a large surface area relative to bed depth is that they are unable to maintain a hot enough fire around the edges to fully burn the coal. In cold weather with a much hotter fire all is well but as soon as it becomes necessary for a minimal fire the shortcomings of the fire pot design become apparent. Even with an Oak or cannon stove design there is a big difference if the fire pot is lined when trying for less heat output. Keeping the heat within the fire pot is crucial for best burning at any firing rate but more so at low rates.

Those base heater stoves that circulate the flue gas around the fire pot will do best with a low fire. Your Chubby should also do much better in this regard because the round fire pot will mix air better and being spaced away from the stove wall will hold the heat within the fire pot better.

It is much easier to hold a smaller hotter fire than it is a larger fire at a low temperature which is why some users resort to making the fire pot smaller during warm weather.

I was able to maintain .03 the entire day. After 10 hours, I opened the primary completely, opened the MPD a bit to give the burn some giddyap. After 10 minutes, shook and rodded, then let it get comfy, then add some coal and allow it to establish itself. Then I closed the damper and set the primary to my normal setting. So far, so good. I have to say, it's hotter than blazes in the house. Had to open the door for some relief.
To liven it up I brought it up to .07 and after coal was added and established, I throttled it back down to .03.

The mano has helped me to see changes immediately instead of waiting and guessing.

And again, thanks to all who chimed in with their advice. I appreciate it a great deal.....

Awesome Crow, I'm thinkin you will experience a lot LESS dead fires now that you can see when draft pressure is trending downward..

Perfect.. :up:
