So I am loving the heat but with this cold weekend we are going into, i am wondering, why the T6 is generating so many coals that I can barely get fresh wood into it.


I pull them togethet in the middle and front but even with the air wide-open it is not burning off, and giving off as much heat.

Granted, I am using mostly large pieces.

When i get home i am going to try and use lots of smaller splits to try and burn off someof those coals.


I thought i saw somewhere as well that there is a air-intake "punch-out" but i don't see it in my manual.

Is there a piece that needs "punched-out" to increase the air-flow, cause if so, i am having no success finding it.
 
The amount of coals is going to vary with the wood species. They won't give off as much heat as a fresh charge of wood, but should be able to keep the stovetop above 300F during the burndown. Try putting a single split of pine or a couple 2x4s on top of the coals at the front of the stove to hustle their burn down.

The air intake opening is located at the back center underside of the ash pan.
 
Put 3 smaller pieces in leave it at the L (air)
Worst case move door handle to open position for about half an hour before u reload
Sounds like u are reloading in about 8hrs or less .. if so don't pack it with as much wood, a full stove will go 10-12 hrs (pe stove)
Or your wood isn't as dry as the stove likes so don't close the air down as far ...
 
Is there a shematic of the interior of the T6 located on-line or here at hearth somewhere?

I have seen where the air intake on the bottom that is controlled byt the arm is, and it seems that it opens and closes with no problem, plus the fire obivously gets more and less air when i open and close the damper.


Would this be a partial function of having a shorter chimney and needing more draft?

It seems to be drafting well, and you could feel air flow when we were installing the chimney prior to connecting the telescoping piece that connects the chimney and the stove.

Would having ash in the pan greatly hinder air-flow?


I also note the the coals in the front-center will get red when the air is open, but stay black in the back and against teh sides, unless open the door for a re-load and then only a little bit after the door has been open for a few.
 
I believe your punch out is already out. Those who have found theirs still in had major back drafting issues. Most could not even run their stove.
The recommendation to put small split in center front on top of coals should work. Its also possible you are into some not so dry wood.

A-HA!

I am loading the stove full every time.

I have noticed that "cheating" with the door cracked does give me a better air-flow and helps to get the fresh wood burning quicker, but i am loath to create what in my mind is a bad habit for me, as i could see myself leaving it cracked, getting engrossed in something and going, "Oh shoot, why is that smoke detector going off..."

I am going to try loading smaller splits, just a few at a time and see the difference it makes.
 
What is the stack height?

The wood i am burning was cut and split by me and is seasoned for 2 years....

now we do have snow, 99% of it is knocked off prior to loading, and on very few pieces there is minimal hissing and only one piece bubbled a very little but (maybe 10/20% of the face of the end of a 5inchround split) only for a few minutes at teh beginning of the load.

I get at little bit of smoke at the beginning of a load, but once it catches, i am getting a very clean burn, with no visible smoke out of the stack.

13-14ft stack. (From top of stove) (Forget exact)

Again, I could feel the draft with with my hand with the 7.5 ft chimney installed.....
(although, that may not be an accurate indicator?)

What kind of wood do you have and is it dry?

it is mostly dry.

It is well seasoned, and we do have snow and the stack is not covered.

I am pulling it into my unheated porch prior to using and try to let it set near the stove prior to using whic results in very little water puddles from exterior ice that has formed, but this is only from 2 out of 10 pieces.


Oh, and what kind??

THat is a great question. It is a mix, with the bigegst % being maple. some hickory, but some "trash" wood as well. (ie a little tulip) (it was all "free")
 
One other thing that helps prevent excessive coaling it to rake all the coals forward during reloads, this helps burn them down since most of the air comes down the glass wash and front manifold. Not much air getting to the back and that is where most of your coals build up.

It's a little on the shy side, but adequate. A bit more stack might pull some more air across the coals. If you want to check this, on a calm day, put an extra 3-4' length of pipe on the top. This is temporary so it can be regular lightweight, galvanized vent pipe, crimp down. If that dramatically improves draft and you like it, make it permanent with proper pipe.

I would like to jump in here as this isn't just with the T6. Its an EPA stove thing that us newbies are trying to work around. I now know why all the long quoted burn times are out there. because coals can last a long time. I too have found 300 stove top temps with large bed of coals but thats not enough to heat a house in really cold temps. And all the tricks to burn them down do work but way to slow for me. I would like a little compermise between long burn time and coals left over. I ended up just scooping out the coals to get on with it. When its 40 out I'll like coals.

Don't bother scooping... don't close it down as far as you do... or don't put as much wood in... coals (big ones ) are energy you are throwing out.. if you need heat in 8hrs and your stove packed full there are a lot of big coals at 8 hrs, you are using to much wood ... its a learning curve - I know my stove has to be packed in by 8 in order for me to fill it at 530ish am BUT I can't fill it to the gills because I will have to many coals and be anywhere from 4-500 ...
Now in the morning I pack it full for the day as I won't get to it till about 5pm
So you can give it more air to burn faster ( don't close it as much as u do now) or use a little less wood- or both

Well for me the problem is I have to start out with the damper fully closed or I'll end up with a cherry red stove. But then 2hrs or less later its down below 500 and then opening damper won't restore temps because by that time the temps are down because only thing left is coals. Now I still need heat so I throw on more wood to get fire. After a few cycles like that there is now more room for wood and the coals that are there aren't enough heat. And the coals just won't go away fast enough. Sure they are heat energy wasted but they are holding up progress for more heat. At these low temps I'm reloading 2-3xs a night. Stove won't come close to heating house unless I can maintain it above 500. It goes up real easy with new wood added but doesn't stay there long basically because the fuel is used up.
I'm only 2 weeks into this EPA stove thing and for the most part I like it. But the whole coaling thing.....well I don't have it figured out yet even using the advise on this forum.

With my Summit I have found that maple and hickory both tend to give more coals than the oak or locust I also have in the woodpile. I also have an unknown species that flares up, then turns into a pile of coals in no time flat and is just annoying. :(
