Possible Causes
Incorrect injector size for gas type, Blocked primary air intake, Misadjusted air shutter, Excessive gas pressure
How to Fix / Troubleshooting
Safety first: Turn off the burner and allow it to cool. Gas adjustments should be done by a qualified technician.
Steps:
- Clean air inlets: Inspect and clean the air intake openings around the burner base.
- Check for drafts: Ensure there are no strong drafts or range hood issues causing flame lift.
- Verify gas type: Confirm the range/cooktop has been converted correctly for the gas type in use (NG or LPG) with the correct SMEG injector kit.
- Adjust air shutter (if accessible): Some burners have adjustable air shutters. Adjust slightly to achieve a stable blue flame with minimal yellow tips.
Warning: Incorrect gas adjustments can be dangerous. If unsure, contact a licensed gas fitter.
