Pressurized by pumping air into the fuel bottle, LIQUID FUEL is forced through the fuel line and into the generator, an extension of the line that runs to the stove's burner. Here the liquid is vaporized to create the "jet" of gas. To start this process, you first have to prime the system by running some fuel into the burner and lighting it, thus heating the generator.
1) Since fuel BOTTLES are refillable, you always know how much gas you have left.

2) Jets and fuel lines need frequent CLEANING. Many stoves have built-in cleaning assemblies for both.

3) Stoves with two VALVES—a fuel control on the bottle and a flame adjuster near the burner—offer the best simmering capability.

Some stoves burn a plethora of PETROLEUM PRODUCTS, from the usual white gas to regular unleaded, kerosene, even diesel. These fuels won't burn quite as well—or as cleanly—as the purer white gas, so you'll have to clean your stove more often.
CANISTER models use a blend of propane, normal (n-) butane, and isobutane in pressurized cylinders. Canister cookers are dead easy to use: Screw the canister to the stove, open the valve, light, and you're cooking with gas. And since it is a gas—as opposed to a liquid fuel that must first be vaporized—the burner head puts out a wonderfully consistent, even flame.

5) Canisters are SELF-SEALING, so you don't have to worry about fuel in your food. The bad news is that you can never tell how much gas is left in a canister, so it's always a good idea to carry a spare.
