600U Flame Rod

The 600U Ultra Flame Rod is a reliable flame detecting system which measures rectified current flow through a flame rod when in contact with a flame. When the rectified current is above the preset value, the flame relay is energized.  LEDs indicate rod fouled and rod grounded and a display provides a visual indication of the flame signal and flame relay to show system status.






  • Capable of connecting to ignition coil or ignition transformer.
  • When using with an ignition coil, the flame rod serves as an ignition rod.
  • Six numeric LEDs arranged vertically provides a visual display of flame signal. 
  • High/low gain plug in selection.
  • Flame rod grounded indication.
  • Flame rod fouled indication.
  • Flame Rod fault indication.
  • Input Power: 115/230 VAC, 50 or 60 Hz.
  • Ambient Temperature: Controller 32°F to 140°F (0°C to 60°C).
  • Flame relay output: DPDT contacts, rated 5A at 125 VAC, 277 VAC, and 30 VDC.
  • Flame rod voltage: 175 VAC at 115/230 VAC input
  • Flame rod current (not firing): Maximum current to ground <.5 mA.
