This specialized vacuum switch monitors negative pressure (vacuum) generated by the blower or inducer motor and confirms that adequate airflow is present before allowing the heater to ignite.\u003c\/p\u003e\n\u003cp\u003eProper vacuum detection helps ensure that combustion air is being drawn correctly through the heat exchanger and venting system.
