Hey fellas, I have a Clayton 1600 wood furnace that I had a hard time keeping under control last winter. I would load the wood stove up to the top of the fire bricks with hardwood. I could get a nice fire going but after a few hours for whatever reason it would try to run away sporadically. It doesn't happen everytime but it has done it enough that I don't trust to run it while my family and I are away or asleep.

One night at 3am, I woke up to house that was very warm inside enough so that i went down to check on it and as soon as i opeded the basement door i could feel it was way too hot. The flu pipe was at 500 degrees according to my IR thermometer but i think there was some ash or creosote insulating the pipe falseifying the reading. I opened the door and it was a raging inferno, enough so that my butt puckered immediately. I shut it down quick and got it under control however that was the last time it ran during the night.

I can barely have the spin draft intake control open maybe a spin or two but it seems like it just gets hotter and hotter over the course of a few hours or so.

My setup is as follows, 6" 90 degree elbow right off the furnace to a horizontal run of 3 or 4 feet straight into a 6" double wall chimney that's 25ft tall. I also have a Fields Control barometric damper installed and set to a .05wc verified by a permanently mounted Dawyer manometer. I called US Stove to verify the baro damper with wood and they said it was OK to use. This furnace also has no electronic controls whatsoever. The previous owner either removed everything or it was removed prior to him acquiring it.

I was tossing around the idea of removing the baro and instead installing a MPD to see if it controlled the air flow better to keep the fire damped down. My draft has reached .11 before the baro was installed. I'm trying to find a way to have a nice steady burn and get longer than 3-4hrs burn. I did manage to speak to the previous owner and he stated that they had to check on the furnace every hour to make sure it wasn't running away on them. He said they never trusted it either. I just moved into this house a year ago so I need to keep this heater for atleast 2-3yrs before I upgrade when funds allow.
 
I also have an oil furnace as backup but with the cost of oil I only run it at night or when we're not home. Oh there on separate flu systems by the way. I still went through over 500 gallons of heating oil. My house is an insulated 1,550 square foot, 2 story house without including the basement which is where the Clayton resides.
 
Things get pretty slow around here in the summer...I'd leave the baro damper...check the door seals, make sure you don't have an air leak.
You could try setting your baro to -0.04" too...
 
Sounds like when the moisture is cooked out of the wood the whole charge ignites!
Good point, could be having to leave the draft open further than optimal due to sub par wood, then when it dries out the whole thing has a huge wood gas bloom, and its off to the races!
That's when its nice having an actively managed lambda machine, right HH?!

Most of the wood tested at 25% or less. I do get a build up of cresote around the baro into the chimney. Seals were replaced last year and I tested them afterwards also. I just thought a manual damper would help keep things under control better than a baro. I did test at .04wc but didn't notice much difference between that and .06wc. Baro flap does like to accumulate cresote after while so I have to keep adjusting the weight from time to time.
 
25% is very wet...20% is barely adequate.
At 25%, if you load 100lbs of wood, you just loaded 3 gallons of water...you are gonna have creosote (unless burning wide open maybe, like with a boiler/storage setup, but it is still very inefficient!)

Yea 25% was a small percentage, maybe half a face cord over 3 month period. What wood i have this year is 15% sounds like bowling pins when you knock them together. The problem is I need 5 more cords to get thru the winter. Having a really hard time find a place to cut dead standing this year, suppliers want 300.00 a cord aswell. I been looking for wood since this past March without any luck.

When the down draft lambda has been burning for about a hour and you open the loading, it is surprising to see how much water is being cooked out of the wood. Wood that is at 14% moisture content.
