What is the difference? Is it a liability issue? Because some stoves call it an option. Don't they all take in air the same way?
 
Yes, and to my knowledge most pellets stoves suggest hooking up the OAK. These stoves use a LOT of air, and sucking it from inside the house can cause a number of problems, including a negative pressure in the house which then affects other systems.
 
I am convinced that CO escapes out of the intake on the things during a power failure without a really strong flue draft. No matter who's pellet stove it is.
