Fondue sets come with one of three different fuel sources: alcohol burners, gel packets including sterno and newer butane burners. Alcohol burners, commonly packaged with fondue sets, provide enough heat for meat and cheese fondues, but too much for delicate chocolate sauces. Gel fuel contains a gelatinized alcohol fuel and can be used for the same applications as alcohol with less concern for spillage compared to completely liquid alcohol fuel. Butane provides an adjustable source of heat. Look for specialty burners for this fuel as an additional accessory for your fondue pot because your set most likely did not come with a more expensive butane burner. You can also use candles, which barely warm the food inside a fondue pot and need to be reserved for chocolates to prevent burning.
Fill the burner base with 2 to 3 oz. of fuel. Use up to 3 oz. for one and a half hours of burning time, and 2 oz. for one hour.
Place the burner cover on top of the base for moving the burner to the fondue stand.
Set the burner firmly on the fondue stand and remove the burner cover.
Use only a lighted match to ignite the fuel by bringing the match toward the hole in the center of the burner cover 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. Set the burner cover on top of the burner base to put out the flames.
