FireBalls/FireStones/FireShapes with Gas Fireplace

Question: I am interested in the FireBall Sets for a gas fireplace. How would I determine which set woould fit my insert? Also, does the burner have to be changed to use your FireBalls?

Answer: Rasmussen manufactures gas logs and alternatives (such as FireStones, FireBalls and FireShapes) for use in fireplaces in which it is safe to burn wood. If your fireplace is a wood-burning fireplace, you can replace the gas log set with a better Rasmussen set. However, if your fireplace is a gas fireplace appliance (which yours is), which is certified to ANSI Z21.50 national standard, or a direct vent fireplace, which is certified to ANSI Z21.86, then you can make no alteration to the fireplace without compromising safety and voiding any warranty and certification. Gas fireplaces are designed as a complete appliance. All components interrelate. Any change in the logs could negatively affect the combustion performance. Any increase in BTU input or flame pattern could result in excessive heat or inadequate venting of the combustion products. Additionally, most gas fireplaces are constructed with a "B-vent", which is inadequate for venting of gas log sets such as those made by Rasmussen. In short, you are stuck forever with the burner and logs that come with the gas fireplace/direct vent appliance if that is the type of “fireplace” you have.
