Coleman Fuel 339 Instruction Manual

To light your Coleman Fuel Lantern 339, first ensure the fuel tank is filled with clean Coleman fuel. Pump the fuel tank 25-30 times to pressurize it. Turn the fuel valve to the 'light' position and hold a lit match near the mantle. Once the mantle ignites, adjust the valve to the desired brightness.
If the mantle is not glowing brightly, ensure that it is properly installed and not damaged. Also, check that the fuel tank is pressurized adequately and the fuel valve is open. If the issue persists, replace the mantle and try again.
If the lantern is not pressurizing, check the pump cup for damage or dryness. Lubricate it with a little oil if necessary. Also, inspect the pump assembly for blockages and ensure the fuel cap is sealed properly.
You should clean your Coleman Fuel Lantern 339 after every camping trip or at least once every few months if used regularly. This includes cleaning the globe, checking the mantle, and ensuring that fuel passages are clear.
When storing your Coleman Lantern, empty the fuel tank and wipe it clean. Remove the mantles if they are fragile or damaged. Store the lantern in a dry, cool place away from direct sunlight to prevent damage to the components.
It is recommended to use only Coleman fuel or white gas in your Coleman Lantern 339. Using alternative fuels can cause damage to the lantern and affect its performance.
To replace the mantle, first ensure the lantern is cool. Remove the globe and old mantle, then tie the new mantle onto the burner tube. Trim excess string and burn the mantle until it turns white. Reassemble the lantern and check for proper function.
A fuel leak can be caused by a damaged fuel cap, worn out O-rings, or cracks in the fuel tank. Inspect these components and replace any that are damaged to fix the leak.
To improve fuel efficiency, make sure the lantern is properly pressurized and the mantles are in good condition. Reducing the brightness to the necessary level can also help conserve fuel.
Regular maintenance includes cleaning the globe, replacing mantles when necessary, lubricating the pump cup, and checking for leaks. Also, keep the fuel tank clean and free of debris.
