Multiple gas pilot burner

A multiple gas pilot burner for a household heating appliance comprising:

• an injector having a first conduit for receiving a flow of a first combustible fluid, a second conduit for receiving a flow of a second combustible fluid, a third conduit connected to and in fluid communication with the first conduit and second conduits and configured to receive the flow of the first combustible fluid from the first conduit or the flow of the second combustible fluid from the second conduit, a single nozzle at an outlet of the third conduit for supplying a pilot flame, a first mixing chamber in fluid communication with the first conduit and a second mixing chamber in fluid communication with the second conduit,
• a single flame igniter positioned to cause an ignition of the pilot flame at the single nozzle;
• and
• a single thermocouple positioned to be heated by the pilot flame and to generate an electrical current when heated,
• wherein the first conduit, second conduit and third conduit each have a central axis, the central axis of the first conduit forming a first angle in relation to the central axis of the third conduit, the central axis of the second conduit forming a second angle in relation to the central axis of the third conduit, the first angle and the second angle each having a maximum value of 10 degrees, and
• wherein the first mixing chamber has one or more first air intake holes and the second mixing chamber has one or more second air intake holes, the first combustible fluid delivered to the first mixing chamber through a first calibrated hole, the second combustible fluid delivered to the second mixing chamber through a second calibrated hole, the first air intake holes and second air intake hole and the first calibrated hole and second calibrated holes being sized to prevent a combustion of the first and second combustible fluids at the nozzle when the ambient oxygen level falls below a specific level.
