It may also render your CO detector completely useless. Aren't the
combustion products are CO and H2O, not CO2 and H2O?


Complete combustion results in only C02 and H20.

Incomplete combustion, such as that in an (relatively) oxygen starved
environment, results in the formation of CO (carbon monoxide).

The trick is knowing wether or not you are having complete combustion.
People have died as a result.
