My plumbing inspector mentioned I need to install a spill switch over my AO Smith natural gas tank water heater exhaust vent. The water heater has WT8840 gas valve. I failed on searching info how to marry SSK-3 switch and WT8840 gas valve. Is there a wiring diagram? Because the one that comes with SSK-3 is useless proposing to use a junction block. I haven't found the thermocouple on the valve. Just ignition wire and 2 thermopile wires
