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.
FEATURES
• 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.
• Q179A1183 is an ìIî port burner with an ignition electrode (spark) only.
• 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.
