Coleman Table Lamp Fuel Tank: Understanding The Pressure

Coleman is a well-known brand of pressure appliances, including stoves and lanterns. The Coleman table lamp is a pressure lamp that burns gaseous vapour from liquid fuel, such as kerosene or gasoline, rather than burning the liquid fuel itself. The lamp's generator is a crucial component as it heats the liquid fuel to transform it into vapour. The generator is a hollow brass tube with a gas tip that has a small hole to shoot the gas vapour into the burner. The generator also has a filler material, typically a spring or cardboard, to aid heat transfer and control the flow of fuel. The Coleman table lamp's fuel valve is another important component as it controls the flow of fuel to the generator and, consequently, the intensity of the lamp's illumination.

Optimal pressure for Coleman lamps

The optimal pressure for Coleman lamps depends on the model of the lamp. For instance, a CQ lamp is said to run on 12 to 15 psi, while the optimal pressure for a 413 and 1970s and newer lamps is said to be 30 psi. However, it is also said that most Coleman lamps run fine at lower pressures.

Coleman lamp fuel types

Coleman lamps are available in a variety of fuel types, including gasoline, kerosene, and propane. The type of fuel used will depend on the specific model of the lamp. Some Coleman lamps can use multiple types of fuel, such as the Dual Fuel™ Lantern, which can use either Coleman Liquid Fuel or unleaded gasoline.

Gasoline

Gasoline-powered Coleman lamps typically use a pressurized fuel tank to deliver fuel to the burner, where it is heated and vaporized. The vaporized fuel is then ignited, producing light. Gasoline-powered lamps may have a single or double mantle, which is the fabric sock that covers the burner and helps to distribute the light.

Kerosene

Kerosene-powered Coleman lamps are typically torch-lit and do not have a pressurized fuel tank. Kerosene lamps may have a single or double mantle and are known for their long burn times.

Propane

Propane-powered Coleman lamps are typically more expensive to run than gasoline or kerosene lamps, as they use more fuel. They are also less reliable in cold conditions. Propane lamps typically have a single mantle and use a disposable propane canister or a bulk tank.

How to pressurise a Coleman lamp

To pressurise a Coleman lamp, you will need to follow these steps:

Firstly, ensure that you have a working knowledge of the components of the lamp, including the fuel valve, the generator, the tip cleaner and the fuel and air tube.

Next, you will need to open the valve. Turn the valve stem wheel counterclockwise, allowing fuel to pass through to the generator. The rate of fuel delivery will depend on how far the valve is opened. Coleman recommends turning the valve "1/4 turn" to light many lanterns.

Once the valve is open, you will need to clean the gas tip. You can do this by using the tip cleaner rod inside the generator, which has a needle on one end designed to poke through the gas tip.

After this, you can continue to open the valve, allowing fuel to flow up to the burner. With the valve stem turned counterclockwise, fuel will enter the valve body and flow past the tip cleaner stem and eccentric block up into the generator.

Finally, you will need to ignite the gaseous vapour exiting the gas tip of the generator. This will cause the mantle of the lamp to illuminate.

Coleman lamp safety

Coleman lamps and lanterns are pressure appliances that burn the gaseous vapour of gasoline or kerosene, not the liquid fuel itself. Here are some safety tips for Coleman lamp users:

• Always read and follow the safety precautions in the Owner's Manual that comes with your appliance. If you don't have this document, check the manufacturer's website to download and print one.
• Keep a fire extinguisher nearby.
• Never modify a lantern for any reason unless you are a professional and understand the associated risks.
• If you have never lit a lamp or lantern before, or are unfamiliar with the process, read the Owner's Manual or seek out a tutorial before attempting to do so.
• Always inspect the appliance before use, even if you used it the day before. Look for things like damp spots on and under the fuel tank and test the function of each control.
• Never fuel or light a lamp or lantern inside your home, cabin or tent. Always perform these tasks outside, in a well-ventilated area where a defective part or user error won't be disastrous.
• Never loosen the fuel filler cap while the lamp/lantern is burning. Turn the appliance off and allow it to cool first.
• Always place the burning lamp or lantern where it can't be knocked over, and where unsuspecting fingers can't touch it. Keep appliances and fuels away from children and pets.
• Always maintain proper ventilation. Appliances need oxygen, and so do you.
• Lower the bail each time you set a burning lantern down. If you leave it upright, it can get very hot. Grabbing a hot bail can burn you and/or cause you to drop a burning lantern.
• Tilt your lantern slightly when de-pressurising, or removing the fuel filler cap. By tilting the lantern to one side and placing the fuel filler cap at the top of the tank, you reduce the chance of liquid fuel spraying everywhere when it de-pressurises.
• Exercise extreme caution if using a vintage 3-piece fuel filler cap with a small hole in the side. Their design was flawed and they are dangerous. It is recommended that you install a new 1-piece cap before attempting to light your appliance.
• Always allow the appliance to cool before touching or refuelling.
• Store fuel in an approved container and away from where you are using the appliances. If at home, store fuels inside a fire-proof cabinet or locker.
• Never modify an appliance or use a fuel that it was not intended to burn.
• Ensure your appliance is clean and functioning properly before you use it.

Coleman lamp maintenance

Cleaning the Lantern:

• At the end of the camping season, or after a prolonged period of use, it is important to clean your Coleman lamp. Start by wiping down the outside and globe with warm water and dish soap. This will help prevent rust and corrosion, improve flame control, and reduce fuel consumption.
• If your lantern uses liquid fuel, it is crucial to keep the fuel line clear of buildup. To do this, drain the tank as much as possible when you know you won't be using the lamp for an extended period. This ensures an adequate fuel supply to the generator and burner.

Storing the Lantern:

• After cleaning the lantern, it is important to store it properly. Wrap the lantern in a sealed plastic bag to prevent spiders and other bugs from crawling inside and potentially blocking the fuel and airflow.
• Additionally, oil the pump cup on the tank's pump plunger with a light machine oil twice a year. This will ensure a proper seal and smooth operation, allowing the pump to push air into the tank effectively.

Replacing Parts:

• Over time, some parts of your Coleman lamp may need to be replaced. The parts that should always be replaced or kept as spares include the mantle, fuel filler cap or gasket, and the generator.
• Other parts that may need replacement include the pump cup, valve stem packing, check valve, and air stem. It is recommended to purchase necessary replacement parts before starting any repair work.

Pressure Maintenance:

• Maintaining proper pressure is crucial for the optimal functioning of your Coleman lamp. The optimal pressure for Coleman lamps varies depending on the model. For newer lamps, a pressure of around 25-30 psi is generally recommended.
• To check the pressure, use a pressure gauge at the S valve after pumping up the lamp as you normally would. Be careful not to over-pressurize the lamp, as this could lead to safety hazards.

By following these maintenance tips and guidelines, you can ensure that your Coleman lamp remains in good working condition and provides reliable illumination during your camping adventures.
