3. Connect the fuel line from the stove to the fuel pump.
4. Place the stove on a stable, level surface.
5. Position the windscreen and heat reflector around the stove for optimal performance and safety.

Connecting Canister Fuel:

1. Ensure the canister is upright and connect the fuel line from the stove directly to the canister.

5. Operating Instructions

Priming and Lighting (Liquid Fuel):

1. Pump the fuel bottle 10-20 times to pressurize.
2. Open the fuel valve slightly for 2-3 seconds to allow a small amount of fuel to pool in the primer cup. Close the valve.
3. Light the pooled fuel. Allow it to burn until the flame dies down (priming phase).
4. Slowly open the fuel valve again. The stove should ignite with a strong, blue flame.

Lighting (Canister Fuel):

1. Ensure the canister is connected and, if inverted, secured with the stand.
2. Slowly open the fuel valve.
3. Light the stove using a match or lighter.

Adjusting Flame:

Adjust the flame intensity by turning the fuel valve. For liquid fuels, a consistent blue flame indicates proper operation. For canister fuels, adjust as needed for cooking.

6. Compatible Fuel Types

The MSR WhisperLite Universal is designed to operate with a variety of fuel types:

• Kerosene
• White gas
• Isobutane-propane (canister fuel)
• Unleaded gasoline

Liquid Feed for Canisters:

When using canister fuel, the stove can be operated with the canister inverted (liquid feed mode) for enhanced performance in cold conditions or when the fuel level is low. This ensures a more consistent and powerful flame.

7. Care and Maintenance

Regular maintenance ensures the longevity and optimal performance of your WhisperLite Universal stove.

Cleaning the Shaker Jet:

The WhisperLite Universal features Shaker Jet technology for easy cleaning. Simply shake the stove vigorously to clear any clogs in the fuel jet. This can be done periodically or if you notice a decrease in flame performance.

General Cleaning:

• After each use, allow the stove to cool completely.
• Wipe down the stove body and fuel line with a damp cloth to remove any soot or spills.
• Inspect all connections and O-rings for wear or damage. Replace as needed using the small parts kit.
• Store the stove in its stuff sack in a dry, cool place.

8. Common Issues and Troubleshooting

If your stove is not performing as expected, consider the following common issues:

• Weak or Flickering Flame: Check fuel level, ensure proper pressurization (for liquid fuel), or clean the Shaker Jet.
• No Fuel Flow: Verify fuel line connections, check for clogs in the fuel filter or jet, or ensure the fuel bottle is adequately pressurized.
• Fuel Leaks: Immediately shut off the fuel supply. Check all connections for tightness and inspect O-rings for damage. Replace any worn parts.
• Difficulty Priming (Liquid Fuel): Ensure enough fuel is pooled in the primer cup and allowed to burn down completely before opening the main valve.
