3. Air tightness. Check whether the air tightness of the purchased gas equipment is good. The simple test method is as follows: turn on the air source, turn off the knob, and brush the pipeline, valve body and interface with soap, without air leakage.
4. Look at the stainless steel panel on the stove panel. The panel should have a certain thickness, and some furnaces are thinner and easy to deform. Some products made of cast iron, steel plate and other materials should be painted evenly, and no foaming or shedding is allowed.
5. The installation position of the switch knob, nozzle and ignition device of the gas stove must be accurate. When ventilating and igniting, ensure that the gas can be ignited and ignited every time. The flame shall ignite all fire holes within 4 seconds after ignition, and an electronic igniter shall be used. When igniting, the human body will not feel electric shock when touching the metal part of the body. If the cooker is being debugged, there will be flame extinction, that is, the flame leaves all or part of the burner hole and backfires, that is, the flame burns yellow in the burner. The flame indicates that there is a quality problem in the furnace.

During the ignition test, check whether the air door of the gas stove is easy to adjust and whether the pot rack is installed correctly. It can adjust the clear outline and light blue flame, and will not produce incomplete combustion phenomena such as yellow flame, black smoke and tempering. These phenomena directly affect the thermal efficiency and flue gas quality of the cooker. Turn off the small air source and keep the small flame with normal flame height 1/3, and it can still burn normally. Do not turn off the fire or backfire.
7. If the stove is still on after the fire is turned off (the phenomenon that the flame leaves all or part of the burner hole), tempering (the phenomenon that the flame burns in the burner), and the flame turns yellow, indicating that the stove has quality problems.
