Abstract
An unregulated gas valve for a water heater that includes an inlet configured to receive a gas flow into the gas valve, an outlet configured to direct a portion of the gas flow to a combustion chamber, a pilot line configured to direct a portion of the gas flow to a pilot flame, and a dial configured to regulate the flow of gas into the gas valve, and further configured to select a water temperature setting.
Claims29
An unregulated gas valve for a water heater comprising:
- an inlet configured to receive a gas flow into the gas valve;
- an outlet configured to direct a portion of the as flow to a combustion chamber;
- a pilot line configured to direct a portion of the as flow to a pilot flame;
- a dial configured to regulate the flow of gas into the gas valve, and further configured to select a water temperature setting;
- and
- a pilot valve configured to shut off the flow of gas to the pilot line if the dial is melted by fire.

An unregulated gas valve for a water heater comprising:
- an inlet configured to receive a gas flow into the gas valve;
- an outlet configured to direct a portion of the as flow to a combustion chamber;
- a pilot line configured to direct a portion of the as flow to a pilot flame;
- a dial configured to regulate the flow of gas into the gas valve, and further configured to select a water temperature setting;
- wherein the dial is configured to rotate to a first position that prevents gas from flowing into the gas valve, and configured to rotate to a second position that permits the flow of gas to the pilot line.
