Master Appliance UT-100Si Ultratorch Soldering Iron_Heat Tool - Manual (Page 6)

1. Only empty fuel tank in a well ventilated
area and away from ignition sources.
Remember butane is heavier than air.
2. Depress the filler valve at the back of the
tank with a small bladed screwdriver and
let the butane gas escape through the
small orifice opening. It takes approxi-
mately one minute for the butane to
escape from the tank. Be careful that the
butane does not hit against your fingers
or hands. This could cause frostbite of
the skin.
How to Empty Tank of Butane Gas if Needed
3. One method is to poke a small bladed
screwdriver through a piece of paper
and then carefully depress the filler
valve. The escaping gas will hit the
paper and not your hand.
4. Never turn gas lever to “ON” and allow
gas to evacuate through the ejector/tip.
Doing this will clog the ejector and lead
to premature failure.
5. Never try to unscrew the filler valve
as it is adhesively bonded to the tank.
Breaking of this bond will destroy the
unit, causing the tank to leak.
