Product description

Maintain the safety and operational integrity of your pellet stove with the United States Stove 80621 Vacuum Switch. 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.
