    All non-cat stoves operate relatively the same way. Load it up, it reaches a peak temp while you decrease the air and then it slowly climbs back down until you need to reload the stove. You can not get a more controllable burn on a 30 than you can on any other non-cat stove.

    With good fuel, you should have the air nearly closed while achieving peak temps. If you expect to throw wood into the 30 and have it cruise at 400-500, you're gonna have a bad time.

    Ok, well that's better. I have Selkirk too with the "deluxe" cap.
    I generally cut the air all the way once the flue temp is up around 300 or a bit more and the STT is about 350-400.
    Fuel is 3 year dry Oak, Pine, Maple, and some Poplar.

    Well, I don't have any expectation for that. More hope, I guess.:)
    Since you're telling me that's not possible, my hope is dashed.:confused:
    I was curious, because chris is saying something a little different.
    I've been reconsidering my Ashford/Sirocco purchase for a couple years when the finances ease, by getting the 30, then moving to the cat stove.
    When the taxes get done, I'll have a much better idea which way I should jump.

    My experience is that if you are burning a load in the 30 and you are trying to stay no higher than 400-500 in your burn cycle, you're smoking from the pipe/chimney.

    Depends too on how long your flue is mine is, only about 16 ft or a little less.

    In the end, if it turns out you budget will not allow for an Ashford or a Sirocco (and I can relate to that), you might want to give the 30 a try since it is so affordable. It probably won't be much different than your Ashley in terms of heat output, but you will get longer burn times and the blower will allow you to stretch out the burn cycles even longer.

    You would think yours would have the tendency to smoke more at those temps.

    BowningBar there is a another NC30 guy we all know (BB), he closes his dog house air off. Especially when loading North/South in a Englander NC30.

    If you want to try it I use metal foil tape to stick over the hole which on my stove is on the bottom front of the stove right under the dog house air location front center of the stove. I am not sure on the NC30 where the dog house air inlet hole is.

    Just to add the dog house air inlet comes from two hole behind the two front legs. If you have it on a pedestal you can not each them.

    You can reach them with the pedestal on. Just need to reach in from the back and use a light. Been there. Done that. :)

    I'm thinking something doesn't jive here isn't the dog house fed from the main intake on the back and the two up front for the airwash? Secondaries being located on back also but smaller of the two intakes.? as the dog house is controlled others are not.

    Nope. It may look and seem that way.

    Primary air (aka- Air wash) comes from the 3" opening at the back of stove (This is controlled by user, but when fully closed, still allows some air. It's Never 100% shut)

    Secondary air comes from a small rectangle in the back, right by the Primary intake (unrestricted/no control)

    Dog house air comes from the 2 small holes located on the bottom front of stove. Behind the legs, but still accessible with pedestal. (Also unrestricted)

    Also, many people have often removed the dog house completely. Just because it's uncontrolled and eats through wood like crazy. Plus, that little hole couldn't provide enough oxygen to fulfill the needs of a Stove that o's pumping out about 30-40 CFM when it's cranking.

    Mine must be wierd then cause when I shove in the control the dog house dies out. Oh well when the season ends I will bring in the small compressor and see whats what on mine. Control below ash lip all the way out dog house feed wide open, all the way in dog dies but air wash still kicking as well as seconds. This is my observation with a pile of coals in front of dog or when I create jet stream tunnel with the splits. at any rate it gets nice and hot.

    That's because there is a loss of pressure. With more Primary, there is more oxygen available. When you close the Primary, as I stated above, that little hole can only draw in so much air. So even though it's unrestricted. Those 2 little holes under the stove, have very little surface area, then the surface area of the one hole on dog house is even smaller.

    I promise your 30 is the same way as all the rest. Those 2 small holes, have a channel that lead to the dog house. If you want to do an experiment. Take 2 magnets, or 2 small pieces of aluminum foil. Cover those small holes behind the front legs. Then open and close your air. This will dissolve any thought of that little, itty, bitty hole, as being your Primary. (Almost every secondary burn stove is made this way. Air wash is always Primary).

    As I said above. People have removed the Dog house completely (like the entire assembly). They do this because of the rush of air that does come out and chew through wood (literally). You have to compensate for a good burn with more primary air, but gives you a better cigar burn (front to back) because you don't eat all your wood in the middle of the stove.

    This is interesting how different results can come from the same stove. In my mind that shows chimney length/configuration and geograhic location could play into how the burning pattern is effected.
