The ODS-0004 monitors ambient oxygen levels in the room where the appliance operates. When oxygen concentration drops from the normal level of 21 percent to 18.5 percent or lower, the sensor triggers a thermocouple response that closes the gas valve and shuts off the burner. This safety mechanism is a core requirement of vent-free gas appliance design. Installation is performed by a qualified gas technician as part of routine service or pilot assembly replacement on LP vent-free fireplace and burner systems.\u003c\/p\u003e\u003cp\u003eThe ODS-0004 is used in residential LP vent-free gas fireplace and burner applications. It is specifically compatible with RH Peterson propane vent-free burners that use the -12 valve. This sensor is a direct service replacement for the original pilot assembly on qualifying units. It is not intended for natural gas systems or for burner models using a different valve configuration. Pilot tubing is not included with this part and must be sourced separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMonitors oxygen levels and shuts off burner when concentration falls to 18.5 percent or lower\u003c\/li\u003e\n\u003cli\u003eThermocouple-actuated gas valve shutoff for reliable safety response\u003c\/li\u003e\n\u003cli\u003eDesigned for LP (propane) vent-free burner systems with -12 valve\u003c\/li\u003e\n\u003cli\u003eServes as a direct OEM-style replacement pilot assembly\u003c\/li\u003e\n\u003cli\u003ePilot tubing not included — source separately before installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with RH Peterson propane vent-free burners that include the -12 valve.

Shut off the gas supply at the valve and allow the appliance to cool completely before beginning any work. Verify that replacement pilot tubing is on hand before starting, as it is not included with this part. All work on gas appliances should conform to applicable local codes and the appliance manufacturer service documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: LP (Propane)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Compatibility\u003c\/strong\u003e: -12 Valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOxygen Shutoff Threshold\u003c\/strong\u003e: 18.5 percent or lower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Tubing Included\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RH PETERSON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ODS-0004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RH PETERSON","offers":[{"title":"Default Title","offer_id":51283930120498,"sku":"ODS-0004","price":190.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279971.jpg?v=1781063472","url":"https:\/\/voomisupply.com\/products\/rh-peterson-ods-0004-oxygen-depletion-sensor-lp-vent-free","provider":"Voomi Supply","version":"1.0","type":"link"}
