Using a voltage meter set on the 200 ohm scale, you should have a resistance reading. The
heater located on the heat exchanger piping should have a resistance reading of 139 ~ 161
ohms and the one located in the water flow sensor valve has a resistance reading of 335 ~ 385
ohms. The one located in the outlet valve has a resistance reading of 335 ~ 385. Voltage
throughout this circuit should be 120 VAC.
