Burning anything creates carbon MONoxide, not DIoxide. But most liquid fuel modern camp stoves burn quite efficiently. You don't need much air exchange to run a small stove indoors for short periods. If you would describe your house as drafty, you already have enough air exchange. If your house seals up pretty well, a window barely open is plenty. Propane burns pretty clean, as does butane. As long as you aren't burning your food and creating smoke you should be good. Ideally you have a woodstove in your house so you can use fuel that is easy to resupply to both cook and keep warm.
