The Nion 3 is a closed jet (pressurized) type burner. To fuel it, we remove the center screw as shown. Note that there is a priming pan under the stove. The stove must be primed in order for it to operate properly. The priming pan shown is the cut off top of a Fosters sized aluminum beverage can which is very light weight.

The Nion 3 has a high setting and a low setting, but even its high setting would take a while if you wanted to bring water to the boil. Basically, the Nion 3 is a simmering only stove. The best use for the Nion 3 is as a back up stove. If your primary stove doesn't simmer, then you could use the Nion 3 for simmering once your primary stove had brought the water to a boil. A little inconvenient, yes, but a lot lighter than bringing something heavy like the brass Trangia burner shown above. Aluminum beverage can stoves are so light, it really doesn't hurt that much to bring a second little burner. The weight penalty is less than one ounce (see exact weights in the Technical Appendix, below). Alternatively, one could bring a Trangia burner which is good for both boiling and simmering, but the weight penalty for carrying a Trangia is far greater than carrying two aluminum beverage can type burners.
