I can't think of anything that would cuase it, except not clearing ash as thoroughly and I'm sure Steve knows very well by now how to do that.

i'm afraid I wasn't clear with my description, sorry.

there is NO unburnt fuel in the fire pot. it burned even single piece from bottom to top and I mean EVERY piece. there is nothing but the ash from what was there after the last shake and the 20#'s of recharge I put in it last.

as William has assured us, these stoves won't go out until ALL the fuel if exhausted

i just lost a rather lengthy reply that I just don't feel like rewriting right now.

the stove and flue are acting in concert now and I can dial it down to -.01 with no loss of draft or fire.

here's the pics I had taken of the burned up coal, all ash that just fell apart when touched and the 2 new MPD's in the stack.

Very nice now you tamed the beast it's time to see what she'll eat. I love how a suspended pot allows such great combustion efficiency.

well, I ran at 495* on the barrel from 5:30 pm last night to 4:30 am this morning, shook and reloaded 13 #'s to bring the fire bed back to the level I started with last night.

1/16" open on primaries, secondaries closed, (but not really, on this stove you actually have wide open or wide open but deflected to a much narrowed and indirect path out because of the simple construction of the door and slide. ), BB, Mano. steady at -.03

i've been used to burning 20 #'s for that time period and stove temp. with T.O.M. which to be honest also held the house 5* warmer BUT, that's 75* and I prefer 70* so i'll take the savings.

things are diff. between a wide some what shallow fire pot and a narrow, tall fire pot. when you have alot of grate surface there's a certain limit to how little fuel you can burn over a certain period and temp.

T.O.M. was a beast in the 0* and 20+ mph wind conditions common around here, slightly over kill above 30*. we'll see how the C40 does in the harsh stuff next yr. the wifey says she wants to keep this one. :D

Steve it appears your ahead of the game with the suspended fire pot. I ran the old G6 at 500° Between an 11hour tend and used roughly 20-25lbs

I built a suspended pot stove and used it for a yr then built TOM and ran him for 2 more so I might have unfair advantage plus these C40's are a select species in their own right

easy street it is. now that I have a management system in place the stove reacts just as you advised.

it will do 1/16" of primary, BB, -.01 Mano. and the check 1/3 open during a 35 mph day with gusts to 50 mph showing 138* as the hot spot and 38.5* on the elbow at the thimble and the fire ambling along wonderfully with a crown of lazy blues.

or, 1/8" primary, BB, -.02 Mano. check closed 15 mph wind and have 417 on the barrel and 102 at the thimble.

or, 1/16" prim. BB, -.03 Mano. no check, 20 mph wind and 500+ on the barrel ( sorry didn't check the stack that time. )

or, or, or, a simply remarkable range of adjustment. PLUS it holds the setting as long as there is fuel in the pot and it doesn't take very much. :D

just realized the REAL hot spot on the stove is the center of the round lift plate under the bonnet. currently 520, thimble 108

can you say "crazy" :o :lol:

You touched on a delicate point with your observations above and that is the fact that these stoves will not do a temperature curve once they are properly fueled and warmed up.
They will hold the settings constantly for the entire combustion cycle. Not just one setting, but; ANY setting. I don't care what the naysayers think. Once you have one of these things you will never go back to a box stove any more than you would drive a big wheel to kindergarten. :D

Urban legend sometimes requires time before truth be told William. BTW, I have a spare load door "grate" if you or Steve need one cast. I'm going to do a couple this summer when both my 40's get new barrels. LMK
