Yellow tipping describes a flame condition in gas appliances, such as water heaters or boilers, where the flame tips turn yellow due to a lack of sufficient air for complete combustion. This condition can indicate improper air-to-fuel ratios, blocked air vents, or issues with the burner. Yellow tipping reduces combustion efficiency, increases the risk of carbon monoxide production, and may leave soot deposits on surfaces. Regular maintenance, including cleaning burners and ensuring proper ventilation, helps prevent yellow tipping and ensures safe operation of gas appliances.
