Raypak 006535F Flame Sensor Electrode Kit for Hi Delta 302-2342, HD101-HD401 Commercial Heaters

This is the flame sensor for Raypak Hi Delta and Delta Limited commercial heaters. These heaters light with a hot-surface igniter, and this separate rod sits in the burner flame so the ignition control can confirm that the burners have lit. Raypak's parts-library photo shows a single metal rod in a ceramic insulator on a two-hole mounting bracket with a quick-connect terminal.
