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.
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.
Household gas appliances should always have a blue flame because it denotes a clean, safe, and efficient burn. However, gas appliance manufacturers recognize the desire for a yellow flame in certain applications where wood was traditionally used.
All flames on gas hobs should burn crisp blue. A weak yellow or orange flame should not be present. Dark or sooty staining around gas appliances including gas stoves and chimneys. Does your pilot light frequently blow out?

Signs that carbon monoxide is being produced include:
Yellow or orange rather than blue flames (except fuel-effect fires or fuel-less appliances that display this colour flame)
Englund suggests starting by opening windows in the room where the fireplace is located, and perhaps opening some other windows on the same floor to create cross-ventilation. Turn on overhead ceiling fans or other ventilation if possible.
If you notice an electrical burning smell or an odor of burning gas, turn off your fireplace, open the doors and windows and call for emergency repairs.
The answer to “is it safe to leave a gas fireplace on all night” is no. There is no gas-burning fireplace that would be guaranteed safe to run all night while you and your family are sleeping. escape is often impossible.
When a flame is turned on, it may appear blue in color. This may be temporary and caused by a few factors: particles in the air such as dust, or an incomplete combustion, which refers to a possible lack of oxygen.
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.
Properly functioning gas appliances are quite safe. A blue flame is one indication of proper function and complete combustion. As discussed, malfunctioning units may generate carbon monoxide, due to incomplete combustion.
Finally, the B-Vent fireplace has the most realistic-looking flames of all the gas fireplace options. This is currently the least popular style of fireplaces, but that doesn't mean it may not be right for your home!
The answer is yes in almost all cases. A gas fireplace pilot light produces a flame from a small trickle of gas and does almost nothing else. This small flame is not enough to pose a threat, and the trickle of gas is immediately burned up, so it doesn't hurt anything either.
To ensure your gas fireplace is free of gas leaks or other dangers, it's important to perform the following safety checks: Open gas fireplace screens or doors for any foul smells. A rotten egg odor—or similar-type smell—is a definite leak indicator.
If you have either a gas fireplace insert or a direct vent fireplace, you should be able to leave your fireplace on continuously throughout the day.
One of the most common problems faced by homeowners with gas fireplaces is the pilot light going out or not staying lit. The pilot light is a small flame that ignites the gas burner, which produces the heat for your fireplace — if the pilot light goes out, your fireplace won't work.
Carbon Monoxide Detectors
For safety reasons, every home should have at least one CO detector located in rooms near gas appliances, including fireplaces. On a related note, your home should also have smoke detectors. Be sure to check and replace the batteries or they won't work!
It's important to remember that your glass doors should always remain open when burning gas logs.
There are two basic rules for leaving a fireplace operating during the night. DON'T leave the unit on overnight. DO leave the flue open so that excess carbon monoxide is vented. The main concern with a gas-burning appliance is the exhaust of carbon monoxide and leaving the unit on overnight is simply risky.
Gas Range Flame Characteristics
When burning natural gas, the burner flames should be almost completely blue with possibly a small hint of yellow in the center of the flame as seen in figure "A" above. When burning liquid propane (LP), the flames will usually have a yellow tip as seen in figure "B".
Natural gas is mixed with air before reaching the flame, a process known as premixed combustion. This allows the gas to burn clean into mostly carbon dioxide and water vapor. The result is the blue flame you see every time you fire up your stove for cooking.
