Now, let's get into the color code of gas fireplace flames. A blue flame means the fuel is being burned super efficiently, while a red or orange flame can indicate that the fuel is not being burned completely. And, fun fact: a purple flame can mean there's a high concentration of radon in the air - who knew?
But, what about flame height? A good rule of thumb is that the flame should be about 2-3 inches high. Any higher, and you might be wasting energy; any lower, and you might not be getting enough heat. It's all about finding that perfect balance, like the Goldilocks of flames - not too big, not too small, just right!
