It isn't recommended to use un-vented fuel-burning heaters back here in northern Europe either, no matter what fuel... houses are quite tight. But, the ODS should shut the heater down before O2 will be depleted so that CO will form. If it is a catalytic heater, it should produce mainly CO2 on quite low oxygen. Some NOx of intake air will be used in the process too.

Don't remember where I read this, but some fire extinguishing gas mixture was designed to lower the O2 content of air down to some 11%... barely enough for human life for a short while, but non-catalyzed burning of most carbon compounds would require 16%... correct me if you find correct percentages somewhere.
