When water level drops below the minimum safe threshold, the device interrupts the burner circuit and holds the lockout until a technician manually resets it on-site. This fail-safe behavior makes it well-suited for hot water heating systems where unattended restart after a low-water event is not acceptable. Licensed plumbers, HVAC technicians, and boiler mechanics are the typical installers for this control.\u003c\/p\u003e\n\u003cp\u003eThis low water cutoff is intended for use on residential and light-commercial hydronic boilers where manual intervention is required after a low-water safety trip. The manual-reset design ensures that the root cause of the water-level drop is investigated and corrected before the boiler is returned to service, rather than allowing automatic restart that could mask a leak or fill-system fault.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eManual-reset lockout holds burner circuit open until a technician physically resets the device\u003c\/li\u003e\n  \u003cli\u003eProtects boiler heat exchanger from dry-fire damage caused by low or lost system water\u003c\/li\u003e\n  \u003cli\u003eInterrupts burner control circuit on low-water condition for a defined safety hold\u003c\/li\u003e\n  \u003cli\u003eOEM replacement part sourced directly from LOCHINVAR\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement low water cutoff for LOCHINVAR hydronic boiler systems.

Shut off electrical power to the boiler and close the gas supply before beginning any control replacement. After installation, verify correct wiring connections at the burner control circuit and test the device by initiating a controlled low-water condition per the boiler manufacturer service procedure. Do not bypass or jumper across the low water cutoff terminals during testing or troubleshooting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Manual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunction\u003c\/strong\u003e: Low Water Cutoff\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: LOCHINVAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L100276822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCHINVAR","offers":[{"title":"Default Title","offer_id":51346772001074,"sku":"L100276822","price":262.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552860.jpg?v=1782089862","url":"https:\/\/voomisupply.com\/products\/lochinvar-l100276822-low-water-cutoff-manual-reset","provider":"Voomi Supply","version":"1.0","type":"link"}
