The wick used in a kerosene heater consists of many bundles of fine fibers and, in accordance with the principle behind it, it is designed to provide a large evaporation area. The kerosene is drawn up from the tank into the wick by capillary action due to the fibers, and is evaporated from the wick and burned.
The wick is ignited and allows the fire to be directed as needed. The spout and wick can be secured upside down inside the canister for storage or transport. Typically the fuel used is a mixture of gasoline and diesel with a ratio of 30% to 70% respectively, although, the amounts may need to be adjusted according to fuel and weather conditions. [1]
