Dual Fuel Pilot Light Burner

A dual pilot light burner assembly suitable for use with a first type of gas and a second type of gas, the assembly comprising:

• a pilot nozzle adapted for providing a flame to a burner,
• an air and gas mixing and intake chamber,
• an injector having at or near a distal end an injection hole, the injector having an inner duct that extends from a proximal gas inlet to the distal end, the injector having one or more holes situated proximal to the injection hole;
• and
• a regulating sleeve located between the injector and air and gas mixing and intake chamber, the regulating sleeve including an inner duct with an upper chamber in fluid communication with the air and gas mixing and intake chamber via a gas supply hole located in a distal end of the upper chamber, the regulating sleeve moveable with respect to the injector for placing the gas supply hole in a first position with respect to the injection hole of the injector, when the regulating sleeve is in the first position the one or more holes of the injector and the injection hole are in fluid communication with the upper chamber of the regulating sleeve and the regulation of the first type of gas to the pilot nozzle is provided by the gas supply hole of the regulating sleeve, when the regulating sleeve is in the second position a portion of the distal end of the injector located between the injection hole and the one or more holes is in contact with a portion of the inner duct of the regulating sleeve and the regulation of the second type of gas to the pilot nozzle is provided by the injection hole of the injector, the gas supply hole of the regulating sleeve having a diameter that is greater than the diameter of the injection hole of the injector, the regulating sleeve comprising structure accessible by an external tool, the structure capable of receiving an end of the tool for use in moving the regulating sleeve between the first and second positions.
