When flue gases spill back into the equipment room instead of venting properly, this switch interrupts the burner circuit to prevent unsafe operation. It serves as a critical safety control in systems equipped with atmospheric burners and draft hoods. Licensed HVAC technicians and plumbers install this component during routine safety audits or as a direct replacement when the original switch fails or triggers nuisance shutdowns.\u003c\/p\u003e\n\u003cp\u003eThis spill switch is suited for residential and light-commercial gas heating applications where draft-hood venting is present. It cross-references to Peerless part numbers 51590 and 60T14-250, making it a direct aftermarket replacement for those original components in Peerless boiler installations where the MCB or MI series control circuit requires a functioning vent safety switch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFunctions as a vent safety shutoff by sensing flue gas spillage at the draft hood\u003c\/li\u003e\n  \u003cli\u003eInterrupts the burner control circuit upon detecting reverse flue flow\u003c\/li\u003e\n  \u003cli\u003eCross-references to Peerless 51590 and 60T14-250 for direct OEM-style replacement\u003c\/li\u003e\n  \u003cli\u003eCompatible with atmospheric draft-hood boiler and water heater applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCross-references to Peerless part numbers 51590 and 60T14-250.

Shut off all gas supply and electrical power to the appliance before removing or installing the spill switch. Verify that the replacement switch is mounted in the same orientation and location as the original to ensure proper spillage detection. Always confirm proper vent draft and flue integrity after installation before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Switch\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: PARTS TO YOUR DOOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 90592\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARTS TO YOUR DOOR","offers":[{"title":"Default Title","offer_id":51233512554802,"sku":"90592","price":109.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633684.webp?v=1780101851","url":"https:\/\/voomisupply.com\/products\/parts-to-your-door-90592-vent-spill-switch-peerless-51590","provider":"Voomi Supply","version":"1.0","type":"link"}
