Bradford White 233-48999-03 Natural Gas Pilot Assembly

This Bradford White natural gas pilot assembly is responsible for igniting the gas in the main burner of a gas water heater. The assembly includes a pilot, thermocouple, and high limit. The pilot light provides the flame needed to ignite the gas coming out of the main burner while the thermocouple detects the heat from the pilot light and sends a signal to open the gas valve. The high limit is a safety device that shuts off the gas if the temperature becomes excessively high.
