I found this on another forum and I tried it out....wow is all can say.....stacking 2 splits the long way leaving a 4-6 in "tunnel" between them, then stacking slits from front to back sideways. Making sure that no wood is touching the sides of the firebox.... It creates an inferno with wood being completed engulfed in flames and much high heat transfer

Agree D5. I like to use 2 logs longways, about 8" diameter. Then use split wood stacked front to back. I read an article once which mentioned that smaller rounds provide more BTU due to the wood grain being tighter than the larger pieces that we have to split. Not sure if this is true but it makes sense to me.
Stay warm...

you too my friend!

my favorite is 4-8 inch rounds.....nothing better!!!!!

I played with different stacking configs with my old conventional. I did find that you got more fast heat out of that stacking but I burned wood faster. I found that a tightly packed pile on top of a good coal bed was the most wood conserving configuration.

I'm not sure if the newer models have a removable restrictor on the blower outlet into the firebox, but if they do, go ahead and remove it for the "coal" setting. I also blocked off the air outlet into the firebox and have all of my air blowing underneath the grates and up into the firebox. As long as I keep the wood on the grates and the ashes cleaned off (shaker grates FTW), the fire really rocks.

I was thinking about trying that out... They new models come with the restrictor in place

Ok I will test this on 400 But the old 200 css here is how I did it . long burn tight stack . Fast heat loose stack . above 0f loose stack below 0f tight stack . Also 200css only had one fan in front so stringers 6-8 inch pieces on bottom to the back in V touching in the back . One cross level then packed it tight long way with 30 inch. This how I turned chimney a shade of purplish blue . Fire builder beware don't do this at -20f If your heating 5500 sq ft your pushing the outer limits but 200css will do it . it was cycling fan on and off . ( note this was 1994 model heatmor 200css with round flu's ) :thumbup:
Thanks d5knapp for the post will give it a try :)

What year was your 400 ? I did notice that bigger pipe in my new 400 and yes its removable. Did your door get hotter when you took restrictor out when burning wood ?

Question how did you get that piece back there that far. Without starting on fire . :bag:

lol heat.....i got good aim :)
Im going to try taking the restrictor tube out tonight, i dont think it should make a different on the hat of the door

staking the wood nice and tight in the back is near impossible. The bigger firebox has been fun for me to get used to. Im not one to just "chuck" wood in. I am very gentle about placing and stacking wood. Its easy to get a nice stacked row in the front half, but in the back half it sucks........i put the slits in half way and then used the poker/scraper to move them around the beast i can

Mine's a 200 css, 2008 model I believe. I didn't notice my door getting any hotter. The piece that restricts the blower tube down that you pictured, I removed. I seem to recall the manual saying to remove it when burning coal so more air blows under the coals.

I think that tube on 400 the main tube is close to 2 inch. I will measure it next time I get a chance.

Is your tube 2 inchs in dia. ? like 400dcss ( it is 2 inch I looked 1 inch with restrictor ) ? my old 1994 heatmor 200 I bet was only 1 inch tub and that was it .

Heat, i took the restirctor out and have been running that way for a few weeks.....i like it. still gets plenty of air out of the front air box and MUCH more air under the grates.....i can get a nasty hot fire going in the back on the firebox under the back blower.....its fun to watch the flames getting pushed up and down, there is just a blue/white tornado!

That's awesome . You have to get some video of that . White and blue flames are some serious heat ! You have to get the video and
shut door before camera has issues . I will try and get some video also and get it on you-tube. white dazzling was always hard to get on the old 200css it had to be -10f or colder to get the white dazzling . :thumbup: I have noticed the 400 dcss does do a lot more blue flames also. That poor wood pile . :bag:

Im trying the double rank of 24 inch pieces tonight one stack in back one in front wood going long way fire box . its set 15 degree difference it heats up the 15 degrees in like 10 mins crazy -3 f and wind . 160f to 145f at boiler ( top of tank ). 150f to 135f on longest run boiler to house 125ft . Mine seems 10 degree difference stat (top) to bottom of tank .( outlet ) This was same on 200css . just way it is .

Got rocket launch :) Try this one for stacking pieces 20 -24 inch and about 3-4 30 inches pieces .
Your making 2 ranks one in back and one in front but interlocking with the 30 inch pieces between
layers this to help hold stack from touching sides of firebox . and leaving 2-3 inch air gap on sides .
only fill it to hieght of top flipper on door and do this below 0f see how it works . This is old trick I learned on old 200css to get water hot fast .
ooo and make sure ashes are cleaned out . for true entertainment watch the smoke coming out of chimney .
I had 5 ft of just heat waves before the smoke turned white . It did this after couple cycles . or after moisture
was out of wood . :thumbup:
Heat550
cycle times were pretty quick to get back to temp.
safety note don't open the door even with switching fans off flames really roll around even with fan off stacked this way.
or atless till it burned a bunch off . or bring door to safety latch and be careful that's how I tried wanted a look see .
not responsible for burned eye brows :) It did burn some rabbit fur off my bomber hat though :) its foe rabbit fur ya :thumbup:

Hahah yah I have caused a minor explosion from openedinh the door right after it shut down and the gasses were condensing....shot some creosote out of the stack
