1 The tank is the old style, that are no longer refillable 2 to light it you would need to push in the silver stem, which will feed gas into the head, once it lights you need to hold that stem in to keep gas flowing, until it heats up, once you can release that stem, then you can advance from the low to the higher settings. You can put that head onto a newer tank. The tubing is a thermal couple, once its hot it allows the valve to stay open. Good Luck. Yup Drifter nailed the startup, I have the exact setup but with the newer tank valve.
