8 Troubleshooting Tasks
To Verify FID Ignitor Function During Ignition Sequence
1 Remove the detector top cover.
2 Turn the FID flame On.
3 Observe the ignitor plug though the FID chimney. The small
hole should glow during ignition sequence.
Keep body parts at a safe distance from the FID chimney while
performing this task. If using hydrogen, the FID flame will not be
visible.
