I guess you mean in respect to passing the EPA requirements, which entail burning at four different rates, low to high; I'm pretty sure I've read of BK owners being able to blow smoke past the combustor when they open up the air, just as I am able to on my Woodstock straight cats, regardless of engineering, cells per inch, etc. I've also seen you mention "residence" of the smoke in the combustor several times. Now, I haven't experimented extensively with this, as I can usually get the heat I need with the air pretty low. It's just that I have seen that a few times when I have some flame in the box and happened to go outside, there can be some smoke getting by the cat.
Oh, man, we gotta stay under 1200 now?? Not what I wanted to hear...a guy can only do so much!It's a bit easier to visually determine if a cat is above 1600, than it would be to tell if it was over 1200. I suppose it's a matter of degrees (heh-heh, funny.)
Just have to do the best I can.
I guess you are talking mainly about when it gets colder outside over the course of the burn but it sounds like there's a lot more to it, when you say it.I'm assuming atmospheric pressure isn't a big deal in most locales but I don't know...
I don't suppose you are in a position to elaborate right now....I guess the key word here is "might."

There are dozens of woodstoves on the market in the interior of AK. There is even one guy that buys and resells WSS stoves. When it goes to -60 and your house is +70, the differential creates a stack effect. If you have a wood stove engineered with a manual air control (damper), cat or non cat, the stove has a low stop engineered to prevent the user from burning lower than it was tested.
Now, with the air opening having a specified volume of air passing through it in a test lab, the amount of cfm of air in the above scenario increases substantially. That will cause the stove to over fire. In 99% of the case, damages will result to any essential element for clean combustion.
If your cat gets to 1600F, you will be using your warranty at some point.
