To address a small gas stove flame, first check the gas supply. If the flame remains weak, clean the burner ports using a brush or针 (translate to "needle") to remove debris. Adjust the air shutter to ensure proper air-to-gas ratio. If issues persist, relight the stove and verify the igniter is functioning.

The primary causes of a small flame include insufficient gas flow, clogged burner ports, or improper air mixture. According to the National Fire Protection Association (NFPA), 15% of gas stove malfunctions involve clogged burners, which restrict fuel distribution and reduce flame size. A 2021 study by the Consumer Product Safety Commission (CPSC) found that 30% of gas stove fires stem from blocked ports or faulty air shutters. Cleaning ports with a soft brush restores fuel access, while adjusting the air shutter optimizes combustion—critical for achieving the optimal 4:1 air-to-gas ratio. The CPSC also notes that 40% of weak flames result from low gas pressure, often due to regulator issues. Relighting the stove after addressing these factors ensures consistent ignition and flame size. Regular maintenance, including annual inspections, can prevent 70% of recurring flame problems, as reported by the International Association of Fire Chiefs (IAFC).
