Offset igniter assembly

Abstract

A gas burner assembly for connection to a source of gas is provided. The gas burner assembly includes a burner body defining an opening therethrough and a generally circular outer periphery. The outer periphery includes a recess therein. The gas burner additionally includes a bracketing unit secured to the burner body and including a igniter holder and at least one igniter being concentric about a vertical axis and positioned within at least one of the recess and the igniter holder. The igniter includes an ignition element that is adjustably positioned to provide an optimal radial distance from the burner body, and wherein the gas burner assembly is configured to operatively accommodate a variety of igniter styles.

         7 . The gas burner assembly of  claim 6 , wherein said radial distance comprises a distance of x. 
     
     
         8 . The gas burner assembly of  claim 1 , wherein said igniter comprises a keyed body for rotational orientation to said burner body. 
     
     
         9 . The gas burner assembly of  claim 8 , wherein said keyed body comprises one or more of a groove and a flat surface among the cylindrical body. 
     
     
         10 . An ignition device for use with a gas burner assembly, said igniter comprising:
 a generally cylindrical body concentric about a vertical axis; and   an ignition element having an adjustable radial position in relation to said vertical axis, said radial position being dependant on an optimal gap distance from an associated gas burner, wherein said ignition element comprises at least one of a spark wire and a silicon nitride hot surface.   
     
     
         11 . The ignition device of  claim 10 , wherein said body comprises a ceramic material. 
     
     
         12 . The ignition device of  claim 10 , wherein the radial position of said the spark wire is different than the radial position of said hot surface. 
     
     
         13 . The ignition device of  claim 10 , wherein said cylindrical body comprises a keyed portion configured to be particularly oriented with an associated burner assembly. 
     
     
         14 . The ignition device of  claim 13 , wherein said keyed geometry includes one or more of a groove and a flat surface amongst said cylindrical body. 
     
     
         15 . The ignition device of  claim 10 , wherein said ignition element comprises a silicon nitride hot surface positioned one of offset from and aligned with said vertical axis.
