Tim you are actually correct about CO2 from propane combustion. When propane burns with proper fuel to air ratio, it produces Carbon Dioxide and Water Vapor. That is why Unvented heaters will cause windows to sweat more readily when in use. Now, an improperly adjusted, or lint clogged burner ports/venturi will cause production of CO (Carbon Monoxide). Excessive gas pressure will also. The best indicators of this happening is the flame being predominantly bright yellow to a dull lazy,rolling orange color that produces Black Soot Tagging Smoke with a eye and nose burning Pungent odor. A Very Dangerous situation. Proper flames are predominantly Blue with Dancing Yellow Tips. FWIW, SoS.
