Keeping your house’s gas heater in proper working order is essential to ensuring efficient energy processes as well as protecting your family safety from dangerous air pollutants like carbon monoxide. The flame color indicates whether your furnace is burning effectively or if it needs adjustment.

Correct Flame Color

Natural gas is composed primarily of methane, a material that gives off a blue color when burnt. A properly burning gas heater should create a sharply defined, blue-colored flame with just a little yellow glowing near the tip.

Incorrect Flame Colors

If the pilot light in your gas heater indicates a lot of orange, yellow, red, purple or green color, this signals inefficient combustion since other condensates are burning along with the methane. These condensates might include tar, dust, oil or rust, all which are potentially hazardous chemicals.

Gas Heater Flame Tips

You can help reduce your family’s risk of exposure to potentially dangerous air pollutants by inspecting the color of your gas heater’s flame at least one time every other month. Flames showing a great deal of color aside from blue should be adjusted by a professional service technician to make sure your gas heater burns properly and securely.
