C2H2To assemble the tank/torch system, take off the plastic cap protecting the regulator connection threads, and open the tank stem with the tank key for just a second, counter-clockwise, and then close it.

- If the tank is full, there will be a loud "whoosh" sound. This will blow out any dirt or dust from the tank stem.- It is important to use only a tank key and not a set of pliers for opening and closing the tank stem. Pliers can round out the corners of the stem and damage it.3Attach the regulator to the tank valve.Firmly push the regulator into the valve opening, and turn the regulator nut clockwise, toward you.

Tighten the regulator nut with an adjustable or universal wrench.

Connect a flashback arrestor to the regulator at the hose valve.Fuel fittings are left-threaded and tighten to the left - that's counter-clockwise.

Turn off the torch hand piece.

Screw the T-shaped regulator adjustment knob into the dimple under the gauge faces, turning clockwise.Insert it approximately halfway into the regulator.

Stand to the side and slowly turn on the tank by turning the tank key counter-clockwise about a quarter of a turn.

There is never a need to open your tank any more than half a turn, at the most. The regulator gauge or gauges will register how much pressure there is in the tank, which is also a measure of how full the tank is, and control the rate of the gas flow. 16Set the left hand gauge using the regulator adjustment knob.
