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
- Low fuel tank (LP)
- Improper gas/air mixture
- Gas orifice adjustment needed
- Improper primary or secondary air
- Too many CFMs on DD blower
With the proper gas and air mixture, a flame of natural gas should be blue with a deep blue inner cone and have no trace of yellow flame.
- With liquid propane gas, some orange tipping is normal.
- There may not be a discernible visual difference between medium and low flame setting.
- In both cases, the flame should be essentially odorless.
- Depending on fuel source, burner size, and temperature (simmer, low, medium high) some vibration or rumbling noise may be heard; this is normal.
- Before troubleshooting, make sure the burner is clean. See Wolf Cleaning Guide for more information.
If burner clicks after ignition or clicks after the burner has been turned off, see Gas Surface Burner Clicking.
- 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.
- 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.).
- If the blower CFMs are too high, it is possible that the power of the blower will suck out the flames on a surface burner.
- Try a lower speed setting on the blower.
- Verify unit is connected to and supplied by the proper gas type and pressure.
- Verify burner rings and caps are positioned properly.
- If the burner cap screws into burner head, verify it is tightly fastened.
- Verify an external regulator was not added to the unit. Units come with an internal regulator. Refer to Gas Regulators Included.
- 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.
- Turn the home circuit breaker to the unit off for 30 seconds and back on again. Retest the unit operation.
- 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.
