Do you have a gas fireplace in your home? If so, then this blog post is for you. Gas fireplaces are becoming more popular because they are less expensive to maintain than their electric counterparts. However, many people don’t know that there are ways to make the flame of a gas fireplace yellow instead of blue or orange.

How to Make Gas Fireplace Flame Yellow

To achieve the best results possible, you should use coal-based fuels such as natural gas and propane. This blog post speaks about an issue that most people may not know about: how to make gas fireplace flame yellow.

11 Steps to Follow on How to Make Gas Fireplace Flame Yellow 

Steps One: Locate the Pilot

There are going to be two states, on and off. In order to turn on your fireplace, you will need to locate the pilot. The pilot is a small flame that uses a smaller gas tank than what you would normally use for it. It lights up when you turn on the fireplace. Usually, the gas fireplace has already been pre-set to the on position. It will take you only a few minutes to locate it once you begin looking around.

Steps Two: Locate the Main Burner

The main burner is located directly under the pilot light. Therefore, the power button or switch that turns this area on should be fairly easy to locate since it is directly under the pilot light. If you cannot find the on switch, it is most likely located on the front of your fireplace.

Steps Three: Locate the Thermostat

The thermostat is usually directly behind where your gas fireplace sits or rests in your home. You can also find it near or around where you locate the pilot and main burner. If you are still looking for it, consult your owner’s manual.

Steps Four: Turn off the Main Burner

It is best to wait until your fireplace has cooled down before you turn off your main burner. Once it is cool, leave it on or manually click it off. Ensure that you have checked all connections and valves to ensure that the fireplace is completely shut down.  

Steps Five: Adjust the Thermostat

Turning up your thermostat will increase how much gas is released, thus making your fireplace burn at a higher temperature and creating more yellow flames.   Whatever you do, do not turn up the thermostat all the way, or you could risk having too high of a temperature which could cause carbon monoxide poisoning.

Steps Six: Turn on the Main Burner

Once you have located and turned on your main burner, it is time to turn on the fireplace. Once you hit the switch, allow a few minutes for the fire to warm up and then release pressure with a click of a button or by turning off the fireplace. You should begin to see yellow flames now instead of orange or blue.

Steps Seven: Utilize a Flame-Coloring Gel

Flame coloring gel, also known as flame-retardant gel, is a product you can purchase at your local hardware or home improvement store. It comes in a small can, and you open it up and then pour the gel into the burner. The gel makes the flames fire from the main burner turn yellow, which gives off a lovely color. Use the gel according to your preference.

Steps Eight: Apply a Flame Colorant

The flame colorant is another product that you can purchase at your local hardware or home improvement store. It is available in a small container and allows you to apply it directly into the main burner area, thus allowing for a quick fix.

Pour the flame colorant into the burner and let it sit for about 24 hours. After 24 hours, turn on your fireplace to allow it to burn off before you take a look at how it looks.

Steps Nine: Utilize Gas Line Antifreeze

This product is available in small containers and allows you to use it along with your current gas fireplace set-up. You can highlight the section where you want to use the gas line antifreeze, simply adding a little bit until you get the desired color of flames.

Steps Ten: Replace Your Gas Line

Replacing your gas line is an option if nothing else works or you are uncomfortable using another product. However, you can order custom-made fireplace gas lines to get what you want; yellow flames. This is the most permanent solution to creating yellow flames for your fireplace, and it will not cause any damage to your home or fireplace.

Steps Eleven: Keep the Pilot Turned On

If you want yellow flames, keep your pilot on at all times. This provides a constant supply of gas to your fireplace so that it is constantly burning and produces the little bit of heat needed to create the yellow flame effect. If you use the steps outlined above for how to make gas fireplace flame yellow, you can do it yourself.

Why Is a Blue Flame Preferred Over a Yellow Flame?

The preference for blue flames over yellow ones comes down to safety. Manufacturers of gas fireplaces, stoves, and other appliances essentially want consumers to think that their appliances are not leaking flammable gases into the home.

The color blue indicates more oxygen than combustible fuel remaining in the appliance, which suggests that the appliance is burning efficiently and safely.

On the other hand, a yellow flame indicates a higher concentration of combustible fuel than oxygen, which could be an indication that the appliance is emitting flammable gas. A high explosive fuel ratio to oxygen can also indicate a leaking furnace or a poorly adjusted pilot light.

As a result, the color yellow is not desirable, and gas appliance manufacturers typically coat the inside of their appliances with a chemical that will make blue flames. Several different additives are used to create the blue color in gas flames, ranging from barium chloride or manganese dioxide to copper sulfate or selenium.
