Using an OAK is more than just about the pellet stove.
You could very well deplete the oxygen in your house if using a gas stove, gas dryer, maybe a gas water heater and a pellet stove at the same time... some folks even continue to use their furnace while the pellet stove is in use. Figure all the combustion air used by these appliances, which COULD be operating at the same time in a "tight" home using INSIDE air, and you can see it's more than just about the pellet stove... it's about the safety of your family.
This scenario may not play out very often, if at all, in your house but it's something to consider....
