This critical sensor, also known as a low draft or pressure switch, is a mandatory safety device that monitors the negative pressure within the combustion chamber. It ensures that the exhaust blower is creating a sufficient draft to safely pull smoke and toxic gases out of the home. If a venting blockage occurs or the exhaust fan fails, the vacuum switch detects the drop in pressure and automatically cuts power to the auger system, stopping the fuel flow and preventing a hazardous situation. Specifically designed for models like the 5040, 5500, and 5660, this switch is calibrated to a precise 0.10\" water column setting. A malfunctioning vacuum switch can lead to \"no fuel\" errors or unsafe operating conditions, making this a vital maintenance replacement for any pellet heating system.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety First:\u003c\/strong\u003e Prevents stove operation if proper draft is not established.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Sensing:\u003c\/strong\u003e Calibrated to detect a vacuum of 0.10\" water column.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Protection:\u003c\/strong\u003e Shuts down the auger motor in the event of a vent blockage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e Built to withstand the fluctuating pressures of pellet stoves.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Compatibility:\u003c\/strong\u003e Fits a wide range of US Stove, Ashley, and Vogelzang models.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e United States Stove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 80621\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting:\u003c\/strong\u003e 0.10\" Water Column (WC)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 1.06\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 3.11\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 3.15\"\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eDirect replacement models\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e5040, 5500, 5660, C-E-201, Ashley 80621\u003c\/p\u003e\u003cp\u003eYou will receive the same product or an OEM-Equivalent that meets the highest standard of the OEM with warranty that will be a direct-fit.
