Q179A,B Gas Pilot Burner Assemblies use the flame rectification principle to prove the flame. Q179A,B are used in conjunction with a suitable electronic flame safeguard control on industrial or commercial gas and gas pilot ignited oil burners.


  • Q179A is a gas pilot assembly (with a flame electrode rod) and ignition electrode, making it suitable for applications requiring an interrupted or intermittent electrically ignited gas pilot burner.
  • Q179B has only the flame electrode and is suitable for use in continuous pilot applications.
  • Primary aerated type burner is equipped with stainless steel fins that provide the proper flame rod area to ground area ratio for maximum flame signal and flame stabilization.
  • Stainless steel electrode(s) are mounted in ceramic insulators, which permit electrode adjustment.
  • Rajah connectors facilitate disconnecting (A1126 has terminal screws).
  • Bracket permits side or end mounting.
