Reznor 234054 Pressure Switch L99H008 Common Questions Is a separateThe Reznor 234054 Pressure Switch is a critical safety component designed for precise differential pressure sensing in Reznor unit heaters. Calibrated to a 0. 20" WC setpoint, this single pole, double throw (SPDT) switch monitors the pressure drop across the heat exchanger, ensuring the induced draft motor is providing adequate airflow for safe combustion. Primarily utilized in UDAP, UDAS, UDX, and SDX series gas fired units, it serves as a reliable
