Set the “USE FLAME TIME” and “TIME FOR CONTINUOUS BURNING”.
To regulate the gas switch to “ON”,
Press the “GAS SWITCH ON” button to ignite the flame.
Adjust the flame height to 12 ± 1mm by regulating the gas flow rate. If the test specimen drips molten or flaming material during the application of the flame, the burner may be tilted up to 450 from the vertical to prevent material from dripping into the burner tube while maintaining an 8 mm±1 mm spacing between the centre of the top of the burner and the remaining portion of the test specimen, ignoring any strings of molten material. If the application the flame to the test specimen side, the horizontal distance is 5 mm±1 mm, see figure below( My company provide 5 mm and 8 mm gauge to measure the distance).
