UST Lighter - High Altitude Operations



Main   Features    Operating Instructions   High Alt Ops    


Windmill, now UST, Stormproof Lighters are engineered to function reliably in extreme environments--withstanding 70-80mph winds, temperatures down to -40 degrees Fahrenheit--and have been used at altitudes in excess of 9000'.  However, successful ignition of your Windmill Lighter at extreme altitudes does depend on several factors.  To help, we've compiled a list of basic and altitude-related ignition tips:


Tips For Successful Ignition

  • Use Proper Fuel in Your UST Lighter
    We recommend that "premium" or "triple refined" butane gas fuel be used at all altitudes in your Windmill Lighter, however use of proper fuel is essential for ignition at higher elevations.  Recommended brands include Vector, Lucienne, or Colibri.
    Whenever possible, keep the fuel tank of your windproof lighter as full as possible.

  • Allow For Fuel Temperature Equilibration
    After refilling your Windmill Lighter with butane gas and before igniting, allow the gas temperature to equilize with mechanism temperature (the gas will be much colder) by holding the lighter in your hand or pocket or letting lighter stand for 1-2 minutes.  

  • Keep Your UST Windmill Lighter From Freezing
    Windmill lighters will work in extremely cold environments (down to -40 degrees Fahrenheit) as long as the lighter itself is kept from freezing.  Simply storing your storm proof lighter in an inside pocket will accomplish this.

  • Adjust Windmill Lighter To Your Elevation
    To improve Windmill Lighter ignition & increase flame height at higher elevations, move the flame adjustment ring CLOCKWISE towards the "-" mark.  Doing so reduces the flow of butane gas and allows for more oxygen inside the combustion chamber, thus enabling ignition in lower-oxygen environments.  At lower altitudes, where oxygen is in greater supply, the fuel adjustment ring of the Windmill Lighter should be moved COUNTER-CLOCKWISE towards the "+" marking, increasing the rate of gas flow.

  • Ignite Storm Proof Lighter Slowly, Deliberately
    Push ignition button slowly in a two-step movement.  First, push the button of your windproof lighter down until you hear the gas flowing and then press the button down all the way until the strike mechanism "clicks."  The sequence is always: gas, spark, ignition.  If there is a spark before gas is flowing, ignition will not occur. 

  • Do Not Repeatedly Press Ignition Button
    Do not push the ignition button of your Windmill Lighter repeatedly in quick, successive fashion as you would a flint lighter.  The act of igniting a Windmill Lighter needs be a slow and deliberate movement.  Repeated sparking will not improve chances of ignition.  Proper fuel; adjustment; and a slow, deliberate motion are the best combination for an efficient start to your Windmill Storm Proof Lighter.

  • Additional Tips
    When not in frequent use, set the flame adjustment of our Windmill Wind Proof Lighter at a medium setting and then adjust "+" or "-" for the desired flame.
