To reduce excessive flames on a stove, first clean the burner ports and remove any debris or food residue that may block gas flow. Ensure the air shutter, a metal plate near the burner, is properly adjusted to maintain the correct air-fuel ratio. If the flame remains too large, check for a faulty gas valve or an overactive igniter. Adjusting the stove’s settings to a lower heat level and verifying that the gas supply is not overfed can also help. If the issue persists, consult a professional technician.

Excessive flames often result from improper air-fuel mixture or mechanical issues. A blocked burner port restricts gas flow, forcing the flame to expand to compensate, as noted by the National Appliance Repair Association, which states that 30% of excessive flame cases involve clogged burners. The air shutter regulates combustion efficiency; misalignment can create a lean mixture, causing a large, unstable flame. Data from the Consumer Product Safety Commission reveals that 15% of stove-related fires stem from uncontrolled flames due to faulty components. Overfed gas valves, common in older models, can also cause this issue, as reported by the U.S. Department of Energy, which estimates that 25% of energy waste in stoves is linked to improper gas distribution. Regular maintenance, including cleaning and adjusting components, ensures optimal combustion and safety.
