This disc functions as a thermal safety device, interrupting the circuit when flue or vent temperatures exceed the rated threshold to protect the system from overheating conditions. Finished in black oxide, the 30388 is a direct OEM-style replacement component installed by licensed HVAC technicians servicing oil-fired residential heating equipment. Its role in the venting system makes accurate temperature rating critical to proper system protection.\u003c\/p\u003e\n\u003cp\u003eThis auxiliary limit disc is specifically used on LRF and LRFV series oil-fired warm air furnaces with chimney vent configurations. It is typically installed in residential heating systems where oil-fired equipment is vented through a traditional masonry or metal chimney. HVAC technicians servicing these furnace models rely on this component to maintain safe vent temperature thresholds during heating operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated at 130 degrees F for precise thermal cutoff protection\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for corrosion resistance in warm air vent environments\u003c\/li\u003e\n  \u003cli\u003eAuxiliary limit function protects against vent overtemperature conditions\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for LRF and LRFV series furnace chimney vent systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on LRF and LRFV oil-fired warm air furnace chimney vent systems as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Always shut down the furnace and allow the system to cool completely before servicing any limit or safety components in the vent system. Verify the replacement disc matches the original temperature rating before installing, as an incorrect rating can compromise system safety. Refer to the furnace service manual and applicable local codes for proper installation procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Auxiliary Limit Disc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: 130 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Oil Fired Warm Air Furnace Chimney Vent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: LRF\/LRFV Series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BECKETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30388\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BECKETT","offers":[{"title":"Default Title","offer_id":51284002799922,"sku":"30388","price":28.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277685.jpg?v=1781065694","url":"https:\/\/voomisupply.com\/products\/beckett-30388-auxiliary-limit-disc-130f-furnace-vent","provider":"Voomi Supply","version":"1.0","type":"link"}
