Answer: What Color Should My Boiler Flame Be?

A healthy gas boiler flame should be mostly blue with a small yellow tip. A strong blue cone indicates complete combustion with the correct air-to-fuel ratio. A yellow or orange lazy flame indicates incomplete combustion — caused by dirty burners, insufficient combustion air, or incorrect gas pressure. A yellow flame produces soot and wastes gas.
