Igniters

Igniter Tips

• Gas stream for quick light-off, but not buried too deep where heat can damage the electrode.
• Check the spark gap, make sure the igniter is not grounding out on metal or burner tile, and confirm the spark is aimed where ignition needs to occur.
• Inspect the ceramic for cracks, because cracks can let the spark track through the insulator instead of jumping Start with igniter placement because even a strong spark will not light reliably if it is not in the right spot.
• If the igniter sparks but the burner still struggles to light, do not assume the igniter is the only problem. Verify pilot gas pressure, main gas pressure, air settings, and light-off position. A good spark will not light consistently if the fuel-air mixture is too lean, too rich, moving too fast, or not reaching the spark.
• Cracked ceramics can cause weak spark, misfires, delayed ignition, or complete ignition failure.
• After placement and condition are verified, check for 120V primary power to the ignition transformer and secondary power of 6000V with an appropriate meter.
• Inspect the ignition cable and connectors for loose fittings, damaged insulation, moisture, corrosion, or poor grounding.
