Installation Instructions
- Disconnect power to the burner system.
- Allow all burner components to cool completely.
- Remove the existing cad cell flame detector.
- Install the included mounting bracket if required.
- Position the detector to maintain a clear view of the burner flame.
- Connect the 15" leads to the primary control.
- Verify proper alignment and secure mounting.
- Restore power and test burner operation.
- Confirm proper flame detection and safety shutdown functionality.
Note: Proper flame sighting is critical for accurate burner operation and reliable flame detection.
Maintenance Recommendations
- Inspect the detector during routine burner maintenance.
- Keep the flame viewing area clean and unobstructed.
- Remove soot buildup from surrounding components.
- Check wiring for damage or wear.
- Verify cad cell resistance periodically.
- Replace the detector if resistance readings exceed recommended limits or flame detection becomes inconsistent.
