Performance requirements
After the main fire burner is lit for 20 minutes, visually check whether the fire melt has tempered. After the main fire burner is lit for 15 seconds, visually check whether each fire hole is present. After 15 seconds of igniting the main fire burner in a cold flame state, it is visually inspected that one-third of the flame hole in a single burner has left the flame
