Certain fireplaces can convert to different fuel types, but this can take quite a bit of work. It’s not as simple as pulling out gas log sets from a gas fireplace and throwing in wood for a wood-burning fire. Each fireplace requires the proper venting for their fuel type. A gas unit cannot manage the amount or type of smoke generated by a wood fire and could lead to smoke filling the room or other safety hazard. Additionally, to switch from wood-burning to gas requires an extensive amount of work that requires a professional. A gas fireplace insert or a gas log set works well to convert an existing wood-burning fireplace to gas. Inserts install into the existing masonry for an easy-to-use fuel alternative without needing the same extensive amount of renovation. If you’re looking to convert from one gas fuel source to another, consider a gas fireplace conversion kit. This allows you to change from natural gas to liquid propane or liquid propane to natural gas. The conversion kit must work with your specified fireplace model to work safely and properly. However, whether the unit can convert comes down to the manufacturing. Certain manufacturers designed gas fireplaces that allow for fuel conversion while others may not. Sierra Flame offers conversion kits for their specified gas fireplace models. Because converting the fuel source involves a complicated process which must be performed safely and correctly, contact a professional to convert your fireplace.
