If you are talking about a chimney vented Kaa-2, I don’t see why it couldn’t, it’s the same flat grate burner.
The behavior between a Kaa-2 and Kaa-4 is similar enough that I used burner setup advice for the kaa-2 when setting up my Kaa-4.

You may want to mix the two coal sizes as the kaa-2 has a smaller water capacity and may dump more when it starts burning well.

From memory, so take that with a grain of salt, some of the smaller keystokers, or perhaps direct vent models....
Specifically recommend AGAINST Buck, because in a power outage the fire may continue to burn without sufficient venting....
Maybe someone remembers the details or their google-fu can find the info?

Yes, All I burn is buck. In the beginning, I thought I try buck, then try rice. The buck burns so nice, I never tried rice..... The secret is; Feed rate no higher than needed to heat the house, and idle fire enough to ignite the fresh coal quicker, without running on the timer. Idle fire is adjusted by adding / removing timer pins. As a rule, no need to touch feed once you find the sweet spot, which is about 4-1/2 turns back from full feed. After that, adjustments are made for shoulder months with timer pins. Timer pins are 4 to 5 pins in every group of pins. I can get my exact settings if you'd like.
