| A safety pilot can be used with a gas appliance. The gas appliance can be a single fuel or a dual fuel appliance for use with one of a first fuel type or a second fuel type different than the first. The safety pilot can include a first thermocouple, a second thermocouple, and one or more nozzles configured to direct combusting fuel towards both the first and second thermocouples. | ||||||

| A pilot fuel ignition system including an ignition circuit for generating sparks for igniting fuel emanating from a pilot burner to establish a pilot flame, a control circuit responsive to the ignition circuit to operate a pilot valve to supply fuel to the pilot burner, and a sampling circuit controlled by the control circuit to maintain the pilot valve operated and to operate a main burner valve to supply fuel to a main burner for ignition by the pilot flame. A flame sensing circuit enabled whenever a pilot flame is established normally disables the ignition circuit, but periodically enables the ignition circuit to test the operability of the ignition circuit. Failure of the ignition circuit to operate results in the disabling of the sampling circuit causing shutoff of the pilot and main burner valves. Also, a warp switch energized whenever the pilot flame is extinguished effects shutoff of the pilot valve interrupting the supply of fuel to the pilot and the main burners. | ||||||

| A gas burner that includes at least one flame aperture is mounted within a burner cone. An electric heating element is mounted close enough to the gas stream which issues from the flame aperture to ignite the gas stream and form a flame. The heating element is also positioned far enough below the aperture so that convection currents will lift the flame above the heating element to minimize flame damage thereto. The ignited flame may be either a main flame or a pilot flame which is directed toward a main flame aperture to ignite the main flame. The gas flow into the gas burner is preferably controlled by a normally closed solenoid-actuated gas valve which is preferably wired in series with the electric heating element to ensure that the electric heating element is energized before the solenoid-actuated gas valve can open.

| A pilot burner having a tubular inlet for receiving fuel from a source thereof and having an outlet for issuing the fuel therefrom to be burned adjacent such outlet. A conduit is coupled to the inlet for directing the fuel from the source thereof to the inlet. A snorkel tube having an air inlet end and a closed end has an opening passing transversely through the closed end thereof and telescopically receiving the tubular inlet whereby the closed end of the tube is disposed between the burner and the conduit. The tubular inlet has an aperture for interconnecting the interior of the snorkel tube with the interior of the inlet so that air from the snorkel tube mixes with the fuel in the burner before being issued out of the outlet.
