Too Much Heat Out of My Stove

Your next step should be to control and stabilize chimney draft. That will require a barometric damper or manual pipe damper, along with (maybe) a manometer to measure draft. You can read many many threads (battles? ) on this forum about baro vs. manual dampers. My vote is barometric because once it is installed and set, it is automatic regardless of outside air temperature and fluctuating wind speeds and gusts. The Field Controls Model RC is designed for coal burning and is popular with forum members. Google it to see pictures. Shop around locally or on-line and you should find it for between $25 and $50.

I say "maybe" on the manometer, because the recommended barometric damper can be set with a calibrated weight to an approximate draft, and approximate is close enough for most stoves. If you have an oil burning furnace or boiler in your house, chances are it has a barometric damper (flapper) installed in the flue pipe.

Yeppers, as I said earlier they will be about the same.

Don, now you got me thinking even harder. When looking at the hottest gases in the middle of the gas stream,that would mean the aftermarket mpd ,with its center holes, would allow more heat out than the solid OEM which only allows the outer layer which is cooler to escape

That I wouldn't have a clue on, my friend. But I can envision the theory.

Stove has been running a few days now, no real issues and going smooth. Thanks to everyone who helped me figure out how to operate my stove. Much appreciated.

Glad to hear the stove is working good for you.

Good Job...
Now that you mastered the basics...
Never forget to go back to them when things get screwed...
Coal likes KISS...
But now you can go forward and play with the extra things in coal world...

Gas is only hotter in the center because of the cooling effect of the pipe. At a damper located on the stove this is not true.
PS Add to that when the hot gas hits the damper the flow becomes extremely turbulent, mixing the gas up.

Someone paid more attention in science class than I did,Thank you lobsterman .
