Thanks for the reply.
It does have a oxygen sensor on it. I did purchase a CO monitor.
This heater is mounted next to a door. When I was trying to use it,
the door was open. The CO monitor reads aroun 22.1 - 22.4. I hope
this info helps you out.

If it was near an open door, maybe the pilot was getting blown out.
As soon as the thermocouple cooled off it would close the gas line.

It *could* still be the regulator, but you'd need to know what the
install instructions call for.
