Good point: While we really wouldn't have an issue with running the water heater overnight I really wouldn't have a reason to do so.
Running the furnace overnight is a common thing everyone does (even at home)--thus how is this fundamentally different than running the generator? Does propane burn cleaner than gas and thus not produce nearly as much CO? (at home the furnace has a separate flue for the combustion products and thus they exit the house..)
I've noticed that the refer doesn't use nearly as much propane as the furnace or water heater. Comparably like a bunsen burner vs a jet engine (at least that is the difference in sounds between the refer and water heater/furnace) and thus the refer probably doesn't produce that much CO/CO2. In addition, if the refer is kept closed all night, it is likely that the cooling cycle wouldn't run as much anyway (given the cooler temps overnight, and no radiant heat from the sun heating the unit).

Simply, the path that CO takes can be unpredictable.

Isn't the resulting CO created from combustion typically hotter than the surrounding air and thus would rise due to convection?
