Very good information CCW. The draft setting on the baro is approximate, but you can play with it to see what works, generally, -.03 to -.06 is where you want hand-fired. Bear in mind the lower you go, the greater chance for a backpuff.

Thanks for the input on the draft. I have lowered it to (approx) .05, according to the baro marks.

I watched very carefully for any problems such as smoke, smell, burning problems, etc. All good yesterday and all night.

I did notice it seems more sensitive to MPD adjustments and am working on determining a 'minimum' setting for the MPD, which I will then mark on the damper itself. Too far closed and I can detect the acrid smell a tiny bit from the top of the load door. Opening the MPD slightly eliminates any smells.

Our CO detectors continue to show 0 ppm.

I only play with these borderline settings during the day when I am fully alert and can watch it carefully.

I do need to get a manometer, for sure. I wasn't sure where the draft should be, but if .04-.06 is normally acceptable, I can work with it a bit. Now to shop for a dwyer ;)

the problem with the mpd and bit coals is that they can plug with soot within a few hours in unfavorable conditions. I'm not a fan of MPD's on bit coal appliances unless the mpd can be placed so close to the stove outlet that soot buildup is minimal.

I don't doubt they are soot catchers, but something I believe helps is opening it each to check or tend the fire. Every once in a while, I give it a couple of good ' rapid open-close exercises to be sure it isn't clogged up. Never had one clogged that I know if, but it's been a habit since my early woodburner days in the 70's. Guess it doesn't hurt :-)


I noticed today when removing the ashes how fine they are compared to before. I figure it is due to a more consistent burn.

I finally did get a solid mature fire the other day. Hot, no smoke, blue flames on top. So I promptly added more coal. Lol. I was building uo the coal bed, which sometimes takes a few hours of loading a shovel or two at a time.

I was planning to add another row of firebrick to keep the fire hotter but am concerned about losing heat transfer. This would mean about half the firebox height would be bricked, up to the base of the stove pipe. Thoughts?

First load of KY Nut is in the basement and about 1/3 of the current fire is burning it now.

First impressions:

1. MUCH easier to shovel than stove coal
2. A mix of nut/pea/some dust from Harper and Gallo. Seems ok
3. It was a bit damp from hauling, but didn't cool my fire as I expected with the initial, single shovel to try it out
4. My plenum is staying at 150F instead of 120F. Not sure if that is coincidence or not, will watch that
5. Much less SMOKE. The fire is hot, so this may also be a coincidence
6. Less volume per ton than stove coal. I have 3 small bins, cut in half 250 gal oil tanks and 1.10 tons filled 2-1/3 of them compared to all 3 with stove. Coal is BTUs/ton, so less volume is actually helpful

I have high hopes for the KY Nut based on all the recommendations from you good folks. As I continue to tweak the furnace and improve the insulation in this leaky old house, it is approaching the 'minimal hassle' and 'reasonably comfortable' marks, versus the previous 'always chilly' and 'Pain in the Butt' levels of years past :D

I know this is an old thread, but I hope keeping it all in one place with updates may help someone else. I know I've searched this site until the letters were ready to fall off the keyboard ( ;) ) and I especially appreciated threads with follow ups when deciding what I was going to copy.

I paid about $15-$20 more for a single ton and had it delivered vs driving for it and using Kittanning seam. It'll be a little less when I get 2 or more ton at a time due to delivery charge. We have been using just about a ton a month. If this KY Nut burns at least as well and efficient, the increase will be minimal- at least until the new GAS TAXES hit :mad:

Thanks again for all the input and patience from everyone. I especially appreciate the 'suggestions' to use better coal instead of, "Hey, Idiot, stop trying to burn crap and get some real coal," as I started those first 2 years before going to the Kittanning and now KY Nut coals 8-)

So true! It'll get a real test the next 2 days as temps dip into the mid-teens.
