    Here you go...here's mine. I just put 2 fresh pieces in it, and throttled it right back. See the hot spot on the bottom ? That's the primary air in...it shoots right to the back, taking the wood gas with it, rises to the top, and flows back toward the front, right over the secondary burn tubes before making the 180 degree turn to head back up, and out the chimney.

    I'd say most of the flames that can be seen in the video there would be considered "secondary", I only see a bit of primary fire...just the way you want it once things are choochin along...:yes:

    spec say the box is 21x13, it could work with 12 inch but I got all my wood to 15-16 ... not going to cut them

    I might decide to change the stove in 1-2 years, this one came with the house, and I will make sure the new one can accept log from north/south side

    I notice that I didn't see a stove top Thermometer , To get a good secondary burn you need to get your stove Up to 500 or better

    When reloading I use the first split to make a trench in the coals front to back in the middle. This allows good air circulation to get that secondary burn rolling. I normally reload with four splits, two across the trench on the bottom and then two angled on top of those. blacksmithden has it right on.

    Yeah you can leave the ashes build up an inch or two and then dig a trench in them right down the middle front to back...I think they call that the "tunnel of love" or something like that...

    I got more of the light dry creosote in the chimney a couple years ago ( nice dry oak ) choking the air back (too much ) over night and choking the air back in shoulder season trying to have small fires smoldering all day. Now we just load up the stove, have short hot fires and let it go out in between burns if it is too warm to keep the stove going all day. Chimney stays a LOT cleaner.

    Keeping your pipe around 600 is a good thing , But don't get obsessed with secondary burn, A lot of the time you won't get major rolling secondaries, Sometimes their doing their thing burning the smoke but you can't really even tell it , There's a lot of factors involved With how much secondary burn you will see , especially with less than full loads

    That seems low to me. I use an IR gun as well.

    Almost hate to throw this into the pot, but is your door gasket good? I mean, is it starting to wear out (flatten/compress) and need replacing?

    hmm you might be on something there, i never replaced it since i got my house and I don't know when/if the previous owner replaced it. that was 3 years ago.

    I'm no expert here, I know there is no smoke going out of the door and I never smell a smoke odor while burning wood in the basement, at this point the fire would suck the air out of the basement which would make sense.

    Take a dollar (canadian) bill n take around the gasket to see if you have a slight resistance when pulling it out....do this the whole way around..

    Actually doesn't look terrible...you can test it with the "dollar bill test"...close the door on a dollar bill (check it all around) if it pulls out easily with no resistance, probably need to tighten the door up. (oops, great advice bear 1998 ! ;))
    You can also pinch the gasket to pucker it up as you were in the video there...that can buy you some time too
