A gas log set consists of a gas burner covered in "firewood" made from fire-proof molded refractory cement, extruded bisque ceramic clay or molder ceramic fibers, depending on the manufacturer and model. Gas logs are a terrific way to enjoy a gas fire in an existing wood burning fireplace and are a good choice for a fire with little mess or environmental impact. The addition of a gas log set can reduce the amount of work associated with building a fire while helping protect winter air quality. But, the best feature of gas logs is the convenience of enjoying the fire. Behr-Necessites offers gas logs from Hargrove, Monessen and Empire, White Mountain.
