Kerosene lanterns require a little more than just lighting the mantles. Go to Coleman's website and find the directions (for free) for KEROSENE lanterns. The generator on the lantern needs to be preheated with alcohol before it will actually light. Make sure lantern is a Kerosene lantern and not a white gas (Coleman fuel) type, there is a difference even though they look similar.
