So these heaters are 100% efficient at creating CO2 (all fuel consumed goes to CO2 production and not other gasses)?? I’ll take one!

The 3600lbs of propane (plus 12910lbs oxygen) will yield 5586lbs of water vapor in addition to the 10924lbs of CO2. Impurities in the fuel will likely cause trace amounts of other gases.
