Someone else will probably provide a better explanation shortly, but you've got to oxidize that wick somehow. Since you're using a mechanical device, you can use the pulse method.
Just get your SS wick wrapped and set up on the mod, with no juice, and give the button some short presses. You'll probably see the legs or (hopefully) the top and bottom coils start to heat up first. Keep pulsing, giving longer and longer pulses, until the whole coil is glowing evenly. You might have to poke the coils around to get them spaced out more evenly.
It's trial and error. Once you've got the coil looking good (evenly lit) THEN give it some e-liquid and see how it performs. If you're happy with the vapor production, fill up the tank, put the top cap and drip tip on, and vape away!
