Fill the burner base with 2 to 3 ounces of fuel. Use 2 ounces for 1 hour of burning time, and up to 3 ounces for 1 hour and 30 minutes.
Place the burner cover on top of the base, and set the burner firmly on the fondue stand. Then remove the burner cover.
Use only a lighted match to ignite the fuel. Bring the match toward the hole in the center of the burner until the fuel catches the flame.
Move the handle on the base of the burner to raise or lower the flame by exposing or covering more holes in the top.
To put out the flames, set the burner cover on top of the burner base.
Look for gel cooking fuel at cooking supply stores or denatured alcohol in hardware stores.
Always wait for the burner to come to room temperature before refilling it with more fuel.
Butane burners provide a more adjustable source of heat; they're more expensive and usually need to be purchased as an additional accessory.
