The instruction manual that came with my kerosene forced-air heater claims that it has two built-in safety systems to prevent the generation of excessive CO. The first is a fuel mixture control valve with an O2 sensor in the exhaust, driving a feedback loop to the mixture control to maintain a stoichiometric burn, and the the second is a built-in CO detector. Both of these are supposed to cut off the fuel supply if something goes wrong. So the CO detector I have mounted on my wall is actually redundant. Of course, as we all know, safety features such as these can malfunction.
Oh yes, concerning the kerosene smell: you can get used to any smell, especially if it means not being able to drive your Mopar if you don't get used to it. Viz.: probably most of you guys think you don't have B.O.
