In english that means a gas valve is slowed to continue to release gas for up to 30 seconds after the pilot fails.

Gas water heater burner lights then goes out. There could a fault in the gas valve s main burner solenoid causing it to draw excessive power and starving the pilot flame solenoid. Clean those tiny vents. A dirty pilot light for gas heaters can also be the culprit for a water heater not remaining on. First cut off the gas supply switch off your heater and wait for the thermocouple to cool off.

Enough air still gets through to keep the pilot light lit. If so replace the entire valve. Burner lights and heats then goes out and takes pilot with it. Gas from this valve lights your pilot light and eventually lights the gas burners that heat your water.

If you can light your pilot light but it keeps going out the first item to check is the thermocouple. One black dial off push to pilot on w hot a notch marking b c d very hot temperature. Gas valve are allowed 30seconds to fall out. The thermocouple will conclude that the pilot light is off and thus close the valve and cut off the gas supply.

A partial blockage however may allow the burner to light but will not provide enough fuel to keep it lit. A complete blockage often prevents the burner from lighting at all. The first fix to try when the water heater burner goes out is simple. Pull aside the filter fabric insert brush clean.

When the water heater is first lit a valve releases gas into the burner and the pilot light ignites that gas. The gas line is what provides fuel to the burner to keep it lit. Your gas valve is what delivers natural gas directly to your water heater. But when the thermostat on the tank calls for the burner to fire up it fails because it is starved for air.

If your burner lights for a short time but then goes out you may have a blockage in the gas valve.
