The basic Optimus camping stove consists of only two primary parts, one of which is the tank. The tank is also known as the gas canister, because it holds the fuel for the stove. This has a flat bottom and serves as the base for your burner. Optimus offers replacement tanks for use when the tank runs out. The tank also has a control knob on the side, which allows you to adjust the size of the flame.
The burner is the other primary part of the basic Optimus camp stove. The burner has three metal prongs sticking out from the side, which function as a plate for holding a pot or pan. Simply place the pot on the prongs, and they will hold it in place. These are also known as pot supports. The pot supports are adjustable for holding different-sized pots. The burner also has a metal ring, which protects the burner from gusts of wind.
In addition to the burner, the Optimus Nova has a gas canister, which attaches to the camp stove with a fuel hose. The stove also uses a fuel pump to slowly feed the gas through the tube. The camp stove comes with a multitool that contains everything needed to tighten the valves and clean out the hose. A quick-connect part lets you easily attach the fuel hose to the stove, and a cup holds the tank in place. You'll also receive a fuel-feed valve, which lets you slowly feed the fuel into the hose, without forcing all the gas out at once.
The Optimus Hiker camp stove contains the tank and burner, along with other parts. A heat shield at the front of the stove protects your hands and clothing from the direct heat, while the stove lid lets you cook foods slower and longer and keeps the heat from escaping. A pump forces fuel from the tank, and a control valve controls the speed with which the heat escapes. A control knob on the front of the stove lets you adjust the size of the flame.
