Natural Gas Ventless Logs Won't Light

I have a FMI 24" ventless log set. No remote. The pilot lights and stay lit. After letting it warm up, when turning on the burners, the pilot will go out. It has been working everyday and just quit today. Any ideas?

Oxygen Depletion Sensor is probably dirty.
It's a small hole on the back side of the pilot housing.
Try clearing it with compressed air.

I blew out the ODS and replaced the thermopile. The pilot still turns off when turning on the burner. The pilot will stay lit okay but then goes out turning on. Would a bad thermocouple cause this?

Thermocouple controls the gas flow to the pilot, not the burner.
Not sure what you should do. Most ventless unit problems are
caused by the ODS.
