If your lighter fails to ignite: Check to see if there is a spark when the lighter mechanism is operated. Make sure that the lighter contains proper level of recommended butane gas (e.g., Newport, Colibri or other Ultra Refined butane brands). Do NOT use brands such as Swan, Ronson or ordinary supermarket butane gas since they may contain higher impurities or different required pressure – long term use will result in clogging up the burner hole or may cause misfire. (see section with more information regarding types of butane gas). In the short term, use of ordinary butane gas which has lower pressures than what is required will cause mis-fires or no igniton at all. Make sure all trapped air is released by BLEEDING (see below). If you fail to get ignition given there is a spark and the gas tank is already emptied, refilled with the correct brand of gas and warmed to room temperature, try the following steps: Adjust the flame setting. Depending on the lighter model, this is either done by hand, using the wheel control at the base of the lighter, or using a small screwdriver (4mm tip flathead) to turn the setting control at the base – i.e., CCW (Counter Clock Wise) to increase the flame height. If you have no flame or a very low flame at room temperature, begin by turning the flame setting screw up a little at a time (1/8 of a turn at a time to a limit of 1/2 turn beyond the initial set maximum level), until the lighter ignites every time at your desired flame height. Note that ignition failure can be caused by flame settings that are too high as well as too low. To recap: BLEED, REFILL WITH HIGH QUALITY BUTANE, WAIT UNTIL REACHING ROOM TEMPERATURE, ADJUST FLAME HEIGHT, IGNITE!
