when the pilot light went out, unburned gas filled the house. therefore the carbon monoxide detector detected it.

Do they make a special CO detector that detects combustible gas? I have never seen one. CO is not present in unburned fuel.

That unit had problems or was very old. If pilot goes out gas valve shuts of in a couple of seconds, unless gas valve as bad. Usually this is due to valve getting wet. Very few standing pilot gas valves fail in the open position. A rareity indeed.
