The Oxygen Depletion Sensor will keep you home safe. It's job to is detect a lack of oxygen when operation your vent-free gas fireplace/burner. The sensor will shut off the burner if there is not enough oxygen in the room to operate safely (21% normal to 18.5% or lower). The reduction in oxygen triggers a thermocouple which closes the gas valve.
The pilot tubing is not included. The ODS-0002 is for use with RH Peterson Propane Vent Free Burners including -15 or -01 remote valves and all G7, G8, G9, G10 and G18 straight valves.
