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.
