The fuel I would use is Chaffing Fuel, this is Wikipedia description,
Chafing fuel is a generic term for various products that are used for heating food. These products often contain methanol, ethanol, or diethylene glycol, as these may be burned safely indoors.
Purchased from Cash & Carry Stores.
Next bit of advice if using this smoker outdoors, take a meter to meter & half of tin foil, fold in half long ways, then wrap around the bottom half of the smoker to stop wind blowing flame out, leave a gap the opposite side to the wind to provide enough air to enable to burn.
We use this fuel and method when we do our Hog Roasts outside.
