We used a pressurized alchohol stove for a decade (with the same preheat requirements of a kerosene stove) and after a few scary preheat fires and stinging eyes we took to preheating the burners with a propane torch.. I know, another fuel, but the convenience and safety of it seem worth it. No more flareups and no smell/fumes.
