This kerosene heater replacement wick, World Marketing of America model 11003, is designed for use in portable kerosene heaters. It facilitates the transfer of K-1 kerosene fuel from the heater's tank to the burner assembly through capillary action, ensuring efficient and clean combustion. The wick is commonly constructed with a cotton lower section for fuel absorption and a fiberglass upper section for extended burning life and improved performance. These sections are typically joined by an entwining thread, often reinforced with an orange cloth band. The wick features a 4-3/4 inch (120mm) diameter. It is compatible with various kerosene heater models, including Everglow PE-8, Futura E-8 Emperor, Henry Island PE-8, Kero-Heat CV-2200, Leslie Locke KH-15, Mega PE-8, Sun Housewares K-200, Envirotemp PE-8, Envirotemp 30478, Envirotemp 30488, Fujika KS-8, KS-8A, and Leslie Locke KH-20. Annual wick replacement is recommended by the CPSC and American Lung Association to ensure optimal and clean heater operation.
