Take on tough outdoor jobs with the Flame King heavy-duty propane torch. Its 340,000 BTU output and flame of up to 28 inches make quick work of weeds in driveways, pavers, and sidewalk cracks. The same torch melts ice on steps and walkways, handles torch-down roofing, burns brush, starts fires, and chars wood for finishing projects.The torch arrives fully assembled and ready to use. Connect the POL fitting to a standard 5 to 100 lb propane tank (20lb or bigger recommended), open the tank valve slowly, and light it with the push-button piezo igniter: no matches needed. Use the flame control knob to set your idle flame, and press the boost lever when you need full power. The 32-inch torch and 10-foot hose let you work comfortably while the tank stays in one place.For best results in cold weather, use a 20lb tank or bigger, since low temperatures reduce tank pressure and flame size. Always check local burn rules and keep the flame away from dry grass, mulch, and buildings.Backed by a 1-year Flame King warranty.
