3. An orifice holder in accordance with claim 1 , wherein said connecting passage comprises a middle portion extending between said first end and said second end, said first end in flow communication with said first tube passage, and said orifice passage and said second tube passage extending from said middle portion.
4. An orifice holder in accordance with claim 1 , wherein said first tube passage is configured to be coupled in flow communication with a first valve and said second tube passage is configured to be coupled in flow communication with a second valve.
5. A tube assembly for use with a gas-fueled appliance, said tube assembly comprising:
an orifice holder;
a first tube coupled to said orifice holder; and
a second tube coupled to said orifice holder, wherein said orifice holder comprises:
a body;
an orifice passage defined in said body;
a first tube passage defined in said body, said first tube coupled in flow communication with said first tube passage;
a second tube passage defined in said body, said second tube coupled in flow communication with said second tube passage wherein said orifice passage, said first tube passage, and said second tube passage are in flow communication within said body; and
a connecting passage defined within said body, said connecting passage couples said orifice passage, said first tube passage, and said second tube in flow communication,
wherein, the orifice holder further comprises a set screw passage defined between a first end of said connecting passage and said first tube passage, said set screw passage being orthogonal to said first tube passage, and said set screw passage is configured to receive a set screw for controlling a fluid flow from said first tube passage to said orifice passage, wherein a second end of said connecting passage comprises a seal.
6. A tube assembly in accordance with claim 5 , wherein said first tube passage is configured to receive a portion of said first tube therein and said second tube passage is configured to receive a portion of said second tube therein.
7. A tube assembly in accordance with claim 5 , wherein said orifice body further comprises a burner coupling formed integrally with said body, said orifice passage defined through said burner coupling.
8. A gas-fueled appliance comprising:
a first burner; and
a tube assembly coupled to said first burner, said tube assembly comprising an orifice holder, a first tube coupled to said orifice holder, and a second tube coupled to said orifice holder, wherein said orifice holder comprises:
a body;
an orifice passage defined in said body;
a first tube passage defined in said body, said first tube coupled in flow communication with said first tube passage;
a second tube passage defined in said body, said second tube coupled in flow communication with said second tube passage, wherein said orifice passage, said first tube passage, and said second tube passage are in flow communication within said body; and
a connecting passage defined within said body, said connecting passage couples said orifice passage, said first tube passage, and said second tube in flow communication,
wherein, the orifice holder further comprises a set screw passage defined between a first end of said connecting passage and said first tube passage, said set screw passage being orthogonal to said first tube passage, and said set screw passage is configured to receive a set screw for controlling a fluid flow from said first tube passage to said orifice passage, wherein a second end of said connecting passage comprises a seal.
9. A gas-fueled appliance in accordance with claim 8 , wherein said first burner is coupled in flow communication with said orifice passage.
10. A gas-fueled appliance in accordance with claim 8 further comprising:
a first valve coupled in flow communication with said first tube; and
a second valve coupled in flow communication with said second tube.
11. A gas-fueled appliance in accordance with claim 10 , wherein said first valve is configured to channel gas to said orifice holder and to a second burner in a griddle mode, said second valve is configured to block said second tube in the griddle mode when in an off position.
12. A gas-fueled appliance in accordance with claim 8 , wherein said orifice holder further comprises a burner coupling formed integrally with said body and configured to couple said orifice holder to said first burner, said orifice passage defined through said burner coupling.
