Simulative Resistance Device Testing - Bradford White UPV75 Series Service Manual

UPV75 Service Procedure VIII – Simulative Resistance Device Testing

Simulative Resistance Device Testing

Step 1. Position power switch on gas control
to the "OFF" position.
Step 2. Disconnect the simulated resistive
device harness from gas control.
Step 3. Using a multi-meter set to the ohms
setting, check resistance of the
simulative resistance device.
Resistance must be within 3,000 ohms
and 48,000 ohms. If outside of this
range, replace the Simulated Resistive
Device.
WARNING
DO NOT use a standard multi-meter
probe for this test. Doing so will
damage connector. Use special pin type
electronic probes or small diameter
wire pins inserted into connector.
