ABSTRACT:
An apparatus and method for operating a pilot burner apparatus and a main burner apparatus of a gas-fired appliance. The pilot burner apparatus draws combustion air from a first environment. The main combustion apparatus draws air from a second environment. In a shutdown condition, such as when a flammable vapor source is accidentally exposed to the second environment, the pilot burner apparatus draws air containing an undesired flammable vapor which eliminates the pilot flame, triggering a gas valve to close and shut down the fuel gas supply to the main burner apparatus and the pilot burner apparatus.
