Oven or cooktop produces excessive smoke or a burning smell during normal cooking.

Safety first: Turn off the appliance if smoke is heavy. Ensure good kitchen ventilation.

• Initial burn-in: For new La Cornue ranges, run an empty oven at a moderate temperature (e.g., 200–220°C) for 30–60 minutes with good ventilation to burn off manufacturing residues.
• Clean spills: Once cool, remove racks and clean the oven cavity, floor, and door with a non-abrasive cleaner. Clean cooktop surfaces and burner bowls of grease.
• Avoid foil contact: Do not line the oven bottom or racks with foil that can trap heat or touch elements.
• Check vents: Ensure oven vents are not blocked by pans or covers.
