Howlin... people have heated their homes for 100 years with propane heaters. Cook stoves etc. When it enters the furnace or cook stove... it's just a vapor like natural gas. That's the way it's burned (in vapor form). It's no more dangerous than burning natural gas from that perspective.

What is carbon monoxide?

Carbon monoxide (CO) is an invisible, odorless, colorless gas created when fossil fuels (such as gasoline, wood, coal, propane, oil and methane) burn incompletely. In the home, heating and cooking equipment are possible sources of carbon monoxide. Vehicles running in an attached garage could also produce dangerous levels of carbon monoxide.

However, consumers can protect themselves against CO poisoning by maintaining, using, and venting heating and cooking equipment and by being cautious when using vehicles in attached garages.
