Q179A,B Gas Pilot Burner
Assemblies
GENERAL
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 "I" 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.
• Stainless steel electrode(s) are mounted in ceramic
insulators, which permit electrode adjustment.
