You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion . When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
Should gas fire flames be blue or yellow?
Gas flames should be blue but can sometimes burn red or yellow.
What color should the flame be on a gas fireplace?
A healthy gas flame will burn steadily with a yellow or orange . If the flame is not yellow or orange it may be a sign that your gas fireplace needs adjusting or cleaning, which should be done by a qualified technician, such as those we have at Kozy Heat.
What Colour flame is carbon monoxide?

What color flame should gas fireplace have?
Proper Flame Colour

Does the flame stay 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. Some newer, more energy-efficient models rely on an electronic ignition that only lights the pilot when the fireplace itself is turned on.
What burns with a blue flame?
For example, copper produces a blue flame, lithium and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame. This picture illustrates the distinctive colors produced by burning particular elements.
What conditions result in a blue flame?
You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion . When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.
Which gas burns with a blue flame?
Carbon monoxide burns with blue flame. In the presence of oxygen including atmospheric concentrations carbon monoxide burns with a blue flame producing carbon dioxide. When nitrogen gas burns, It has no color, odor or taste, and produces water when it burns in air.
How do I know if my gas fire is leaking carbon monoxide?
- You see black, sooty marks on the front covers of gas fires.
- There is heavy condensation built up at the windowpane where the appliance is installed.
- Sooty or yellow/brown stains on or around boilers, stoves, or fires.
- Smoke building up in rooms.
What does it mean if your gas flame is orange?
A gas flame appearing yellow or orange in color or behaving with pops of yellow or orange indicates an improper ratio of oxygen for combustion . Often this improper combustion is temporary and could be caused by dust particles or a dirty burner that needs cleaning.
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.
Can you adjust the flame on a gas fireplace?

What color should the flame be on a ventless gas fireplace?
Vent-free fireplaces provide heat by burning natural gas or propane rather than wood. The flames in a vent-free fireplace should burn blue , although the flames may occasionally burn orange if dirt or other particles get inside the heater and burn. However, flames should not burn yellow.
