I'd like to understand better why this stove is inherently more dangerous if used indoors than a regular gas stove
Any takers on this one?
I can't think of any reason why it would be inherantly any more dangerous than a gas stove. A gas stove MIGHT have an exhaust hood, but if it doesn't then any fuel burning cleanly in your house like methane or propane or even a butane candle could start to produce carbon monoxide if there's insufficient O2 in the air. So, a gas stove burning methane would be just as dangerous to use in a house as a propane stove, so far as I can see. I expect the gas stove might have more reliable controls, tho.
I believe that much of the reason why Coleman warns you against using your stove in an RV or any enclosed space is because of the limited air volume in a camper. Outdoors, there's little concern that the O2 in the atmosphere is going to become depleted, but that possibility exists in a camper. However, if there's even a slight breeze and if a person keeps the camper windows open so that the breeze can blow through the camper, that ventilation would drastically reduce the liklihood of CO being produced by the propane stove.
Also, of course, Coleman's lawyers are trying to keep the company out of court. They simply want to warn people against doing anything that even smells like it could have an unhappy ending cuz that might result in the company ending up in court.
Any major appliance manufacturer that produces natural gas stoves can't tell you that you shouldn't use them inside, but they undoubtedly warn you 16 times in the owner's manual about providing adequate ventilation to avoid the production of carbon monoxide.
That multi gas detector looks fine to me. I notice that it detects both CO and propane. You could save a few bucks and just buy a CO detector if you disconnected the propane line each time after using the stove. You're not going to need that propane feature once the kitchen renovations are finished.
Anybody else? Why isn't using gas stove just as dangerous as using a propane stove indoors? It's an excellent question cuz I haven't got an answer.
