How do you replace the wick on a heat mate kerosene heater?

To replace the wick on a Heat Mate kerosene heater, first ensure the heater is turned off and completely cool. Remove the fuel tank and then unscrew or unclip the wick access panel, typically located at the bottom of the heater. Carefully pull out the old wick and insert the new one, making sure it is properly positioned. Finally, reassemble the heater, reattach the fuel tank, and test the operation according to the manufacturer's instructions.
