Before starting to use a gas burner, you need to be familiar with the precautions and operating instructions on the burner packaging. During the first two minutes, the burner should be heating up. To avoid gas flashing during preheat, do not allow burner to exceed 75 degrees from vertical. After preheating, you can use the burner at any angle. Replacement cylinders should only be produced outdoors, away from open flame sources, repellents, electric heating devices, and other possible sources of ignition. When working with a burner, it must be ensured that it is sufficiently clear of the movement paths of people and animals to eliminate possible contact with the working burner and the heating object.
