Replace Hot Water Tank Propane Gas Valve

There's more to it than what meets the eye. Don't mess with explosives, ejector seats, parachutes or gas appliances if you don't know what you're doing. All the parts work as a system and you don't mismatch parts. Clean all gnds. Connectors and the igniter. I also add gnd. Wires to be sure everything is bonded properly. Ignition and valve operation rely on milliampere detection through the flame and the gnd. Circuit and it hardly takes anything to Lock out the valve. Craig
