From my T/P days:
Condition levers usually turn fuel on as one moves them forward, then they become pitch/rpm control levers. Conversely, when at feather, further aft movement of the condition lever, turns the fuel off, shutting down the engine.
Not being familiar with the new Kingair, I'd speculate that the condition levers are fuel on/off levers, and separate pitch & power levers are provided.
