- 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:
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 operation. If flames are consistently high regardless of natural gas or LP gas supply, continue with further troubleshooting:
- Verify unit is connected to and supplied by the proper gas type and pressure. See Wolf Gas Product with the Wrong Gas Type.
- Verify burner rings and caps are positioned properly. Refer to How to Remove Burner Rings and Caps.
- If the burner cap screws into burner head, verify it is tightly fastened. See Dual Fuel and Gas Cooktop Burner Cap Assembly Nut.
- 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.
- If burner continues to click after ignition, or clicks after the burner has been turned off, see Gas Surface Burner Clicking.
- 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.).
- 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.
