What Color Should The Pilot Light Flame Be?

blue.
The color of the pilot light should be blue because that means that only natural gas—without any other condensates—is reaching the pilot light through the gas main. The principal chemical compound found in natural gas is methane, and methane burns blue.

What color should pilot flame be?

blue
Inspecting a Gas Furnace Pilot Light Flame
A natural gas flame should be a bright blue color with a small amount of yellow at the very tip. A propane flame will have more of a bluish-green flame with a tinge of yellow at the tip. The flame should strong enough to cover about 1/2 inch at the end of the thermocouple tip.

What should pilot light flame look like?

A proper pilot flame should be blue with a yellow tip and should be strong enough to cover about 1/2 inch at the end of the thermocouple tip. If the flame is too strong and improperly adjusted, it will be blue but may be noisy and lift off the thermocouple, causing improper furnace operation.

Why is my pilot light flame yellow?

The most common reason why a pilot light would start to burn yellow is that the air intake valve to the pilot light is clogged with dirt.If there is a small amount of dirt blocking the air, the yellow color might only be at the tip of the flame. If there is a large amount of dirt, the entire flame will burn yellow.

Should a gas flame be blue or yellow?

A healthy, properly burning flame on gas appliances should be blue in color, sometimes with a tiny tip of yellow, with a little light blue triangle at the center. This blue color flame indicates that there is safe, efficient and more complete fuel combustion.

What color should the pilot be on a gas fireplace?

A pilot light on a gas-burning appliance should be blue. Another flame color, especially yellow, means the appliance’s gas-to-air mixture is unsafe and needs to be checked.

Why is my gas flame yellow and not blue?

Gas burners burn blue if the ratio of fuel to air is correct. A yellow burner flame is a symptom that the burner is not getting enough air for complete combustion of the gas. Correcting this problem involves adjusting the burner’s air shutter to admit more air, something that an experienced do-it-yourselfer can do.

Should a pilot light be orange?

The flames from traditional pilot lights should burn a bright blue color. If your pilot light’s flame is orange or yellow, it is burning inefficiently due to a lack of oxygen. The thermocouple should sense when this happens because the heat from the flame will not be as hot as it should be.

What should a pilot light look like on a gas fireplace?

A healthy pilot flame will be much like a blue “blow torch” flame. It will shoot sideways and be directly on your thermocouple and thermopile sensors. An unhealthy yellow pilot flame is more like a “candle”. It will shoot straight up in the air and will not engulf your sensors.

Why is my gas heater flame yellow?

If you have a yellow, orange, or red burner flame, this usually means that your burner is not receiving enough air for complete combustion. Besides wasted gas, higher energy bills, and more soot, the main danger of improper combustion is the increased amount of carbon monoxide (CO) produced by the combustion process.

How do you fix a yellow flame on a gas fireplace?

Make Sure the Damper is Open
By opening the damper to the fireplace, you are allowing proper ventilation. This will control the color of the flame. To adjust it so that the flames have an orange or yellow tip to them, lower the air input. You can do this by changing the damper or by closing the air shutter.

What color should the flame be on a propane heater?

Blue
The Color of Burner Flames in a Properly Functioning Furnace is Bright Blue. The burner flames of a properly functioning natural or propane gas furnace should be predominately blue. The flame from each burner should have a “whooshing” sound and have a lighter blue triangle in its center.

Why is my pilot light flame too high?

So, if your pilot light flame also tends to be too high, ensure that your fireplace doesn’t have a button to bring the flame up or downward. If there’s no such button, adjust a screw on the fireplace. Turning it clockwise will reduce the fire whilst moving the opposite direction will raise it.

What color should the flame be on a hot water heater?

blue
The flame of any natural-gas appliance should be blue in color (with maybe a little yellow at the very tip of the flame). The orange flame of your water heater indicates that the gas is not combusting efficiently, and it’s a sure sign that your heater needs adjustment or repair.

Can a pilot light cause a fire?

When the appliance is turned on, a valve releases more gas, which is ignited by the pilot light.If this leak continues, its concentration may reach a point where a spark – such as that from a cigarette lighter, static electricity, or even the pilot light itself as it is re-lit – will cause a fire or even an explosion.

What is the difference between a yellow gas flame and an orange gas flame?

What is the difference between a yellow gas flame and an orange gas flame?There is a yellow flame. Carbon monoxide is produced. The burning of dust is represented by the orange flame.

Why is my gas flame red?

Red or yellow flames means there could be a problem, such as incomplete combustion. This color is caused by very fine soot particles produced by the flame, which burns at nearly half the temperature it is supposed to.

Why is my gas stove flame green?

Green flame can be caused by copper salts or corroded copper parts contaminating the flame with copper ions. This can “naturally” happen, and the minute amount of copper is harmless. However if someone intentionally put larger amount of toxic copper salts there, that might be dangerous.

Does yellow flame mean carbon monoxide?

A yellow flame indicates improper adjustment and a possibility of excessive carbon monoxide. Do not use the oven as a source of heat.

Is my pilot light too high?

Next to the “Pilot” indicator on the furnace’s control switch, there is a small screw located near the pilot light-thermocouple assembly.If it extends well above the thermocouple, it’s too strong. If the flame covers the top of the thermocouple and burns steadily with a yellow tip, that’s just about right.

Should the pilot light always be on in a gas fireplace?

Should the pilot light always be on in a gas fireplace? Most gas fireplaces rely on a “continuous pilot light,” a type of pilot that remains lit so long as gas is flowing to the unit.If you have a continuous pilot light system, you should always see a pilot flame unless you have manually turned the system off.
