Yellow Flame. The flame of a gas fireplace should ideally have a predominantly blue color. A blue flame indicates complete combustion, with optimal oxygen levels. On the other hand, a yellow flame can be a sign of incomplete combustion.
With gas fireplaces and fire pits a yellow flame is achieved by reducing or eliminating the air mixed with the gas. This results in the incomplete combustion of the carbon molecules in the gas. That incomplete process leaves leftover carbon that is heated and produces a yellow glow to the flame.
Yellow flames occur when flames are not hot enough and full combustion didn't complete. These flames also come with the presence of carbon monoxide, in which even slight exposure can have major consequences. Yellow flames are a serious worry.
The first thing you need to know is that blue is the correct color for a pilot light. The reason that this happens is that methane—the primary chemical compound in natural gas—gives off a blue radiance when it's ignited. You'll probably see a touch of yellow near the tip of the flame, and that's normal.
When you see yellow or red flames, it usually means the gas isn't getting enough oxygen to burn properly, leading to incomplete combustion. This poses several risks: Safety Risks: Incomplete combustion can produce carbon monoxide, a dangerous gas that is particularly hazardous indoors.
A healthy grill flame may have a little yellow on the tips of the blue flame, but if you're seeing a solid yellow flame, something isn't quite right. Check a few things: Regulator Pressure The most common cause of yellow flames is low gas pressure from the regulator, which is an easy fix that you can do at home.
Too little air, and you'll get a low yellow flame. If the flame looks like it's floating above the burner, there is too much air coming through. The correct amount of air should give you consistent, approximately 1-inch blue flames with a yellow tip across the entire burner, and the flames should touch the burner.
A proper flame should be a soft blue (Natural Gas) or blue with slightly yellow tips (LP Gas). If the flames are not the right color, too high or too low, the flame may need to be adjusted.
Blue flames are good. Red flames and yellow gas flames... not so much... Blue flame versus red flames is an issue of safety, proper combustion and saving gas. Gas normally burns with a blue flame but sometimes it burns with yellow or red flames when there is a problem.
Yellow – In addition to being a sign of inefficient combustion, yellow flames indicate the production of carbon monoxide, an odorless, colorless, tasteless gas that can cause headaches, nausea, hallucinations, and in severe cases, blackouts.
The little flame you see in your gas fireplace after you have turned it off is called a pilot light. A Standing Pilot Light runs constantly, whether your fireplace is on or off.
If the flame continues to burn yellow or orange, this could be a more serious problem that requires professional help. Incomplete combustion could cause too much carbon monoxide (CO) to be produced so it is imperative for a qualified professional to check.
The flame of a gas fireplace should ideally have a predominantly blue color. A blue flame indicates complete combustion, with optimal oxygen levels. On the other hand, a yellow flame can be a sign of incomplete combustion. This can lead to potential hazards and reduced efficiency.
Yellow or orange flames with a gas burner mean that the flame is generating carbon monoxide. Turn the burner off right away, and call for professional assistance.
Adjusting the shutter allows more or less air to mix with the gas. More air will reduce orange color in the flame. Less air increases the orange color and legnthens the flames. Idealy there will only be slight orange tips on the mostly blue flames.
In general, when you see a yellow gas pump handle, it signifies that it is an e85 gas pump. E85 is an alternative fuel often known as biofuel that is commonly created from corn. Ethanol is an alcohol compound that is used as an additive in most common fuels (unleaded, super unleaded, and premium).
A clogged or faulty burner can cause performance issues resulting in a low gas flame. In addition, carbon build-up, gas residue, and debris can inhibit the burner's ability to function correctly, leading to premature failure. If cleaning the burner doesn't solve the problem, it may need to be replaced.
Propane. The gas leaving the tank in a propane system is usually very high pressure. The regulator at the tank will reduce pressure to around 2lb or 56″ WC, which is still too high for a fireplace. Therefore, it will require the installation of an adjustable ½ lb regulator.
