Simulated Resistive Device Testing
Step 1. Position power switch on gas control to the
"OFF" position.
Step 2. Disconnect simulated resistive device from
gas control.
Step 3. Using a multi-meter set to the ohms setting
check resistance of simulated resistive
device. Resistance must be within 25,000
ohms and 45,000 ohms. If outside of this
range replace simulated resistive device.
