Wolf Gas Surface Burner Flame Quality Issues


  • Spill-over or dirty burner
  • Burner placement or assembly
  • Pot or pan size
  • Wrong type of supply gas
  • Gas supply pressure excessive
  • Gas supply insufficient or poor quality
  • Faulty regulator
  • Excessive humidity


  • Erratic burner flame issue
  • Low or poor burner flame
  • Orange or yellow flame
  • Pulsating, vibrating, or bouncing flame
  • Is it normal for a liquid propane (LP) gas appliance to have a tall burst of flame when lit for the first time each day?

Steps to Verify Issue:


If burner clicks after ignition or clicks after the burner has been turned off, see Gas Surface Burner Clicking.

Tall Flames

  • For liquid propane (LP) units, an initial tall flame occurs on first start-up of the day due to a build-up of gas and the natural properties of LP. This is normal.
  • If flames are consistently high regardless of natural gas or LP gas supply, see the General Troubleshooting section.

Orange Flames

  • Excessive humidity in the room can lead to orange and yellow flames.
  • This is especially common in the winter months when homeowners use humidifiers to add humidity to the air.
  • Construction in the home may cause orange flames due to materials in the air (paint fumes, staining, drywall compound, floor sanding, etc.).

General Troubleshooting

  1. Verify unit is connected to and supplied by the proper gas type and pressure.
  2. Verify burner rings and caps are positioned properly.
  3. If the burner cap screws into burner head, verify it is tightly fastened.
  4. Verify an external regulator was not added to the unit. Units come with an internal regulator. Refer to Gas Regulators Included.
  5. Verify burners are clean and dry:
    • If water spilled over recently or if the unit was recently cleaned, the ignitor may be wet.
    • Let the unit dry or use a hairdryer to speed up the process.
  6. Turn the home circuit breaker to the unit off for 30 seconds and back on again. Retest the unit operation.
  7. If there are still burner flame quality issues after completing these steps, no further troubleshooting advice is available. Contact Factory Certified Service to schedule an appointment for repair.
