Overview
The Q179A is a gas pilot assembly which includes an electrode for electric spark ignition of the pilot, and a flame electrode for electronic flame detection when used with an R190 or similar device. Flame electrodes are provided for use with the various burner tips, and orifices are provided for operation with natural and mixed, manufactured and LP gas. The assembly is provided with a third electrode which acts as a ground for the flame and as a shield between the ignition port and the flame electrode. The current through the flame rod when used with an R190 relay is approximately 2 microamperes.
