well to be fair, the only gas water heater without a vent that I know of was at my last apartment. Maybe they don't make them like that anymore. But still, not all gas appliances (for example stoves and ventless heaters) have vents. These days oxygen sensors are mandatory and carbon monoxide detectors are cheap, so this is something I would do myself in such a situation.

However, I will admit that telling OTHER people that it's possible is probably a mistake, and thus take back what I said. It's far too easy to do it wrong and put people in danger.
