ABSTRACT:
A gas valve includes a gas inlet in fluid communication with a first chamber, a second chamber in selective fluid communication with the first chamber, a gas outlet in selective fluid communication with the second chamber, a pilot light outlet in fluid communication with the second chamber, and a bypass channel in fluid communication with the second chamber and in fluid communication with the first chamber. The bypass channel limits bypass gas flow to an amount that is insufficient to ignite a pilot flame at the pilot light outlet when the second channel is in fluid communication with the gas outlet.
