Gas burner flame is yellow, lifting, or noisy (roaring sound).

Safety first: Yellow flames can indicate incomplete combustion and carbon monoxide risk. Ensure good ventilation.

• Clean burner: Remove burner head and clean thoroughly. Check the venturi (air intake) for spider webs or debris and clear them.
• Check air shutters: On some Summit gas ranges, adjustable air shutters are located near the burner orifices under the cooktop. Slightly open or close the shutter while the burner is lit (by a qualified person) to achieve a steady blue flame with small yellow tips.
• Verify gas type: Confirm the range is set up for the correct gas (natural vs LP). Incorrect orifices can cause yellow or lifting flames.
• Professional adjustment: If flames remain unstable, have a technician check regulator pressure and orifice sizing.
