Operating the Rapid Preheater
The rapid preheater is used to quickly bring the carburetor to operating temperature, allowing for a smooth and efficient start-up of your Petromax lantern.
- Fyld brændstoftanken: Ensure the lantern's fuel tank is filled with appropriate fuel (e.g., paraffin/kerosene).
- Byggetryk: Pump air into the fuel tank using the integrated pump until the pressure gauge indicates sufficient operating pressure (typically 1-2 bar).
- Activate Rapid Preheater: Open the valve of the rapid preheater. You will hear a hissing sound as fuel and air are mixed and ignited.
- Ignite Preheater: Use a lighter or match to ignite the mixture exiting the preheater nozzle. A small, steady flame should appear.
- Preheat Duration: Allow the preheater to burn for approximately 60-90 seconds, or until the mantle begins to glow faintly. This indicates the carburetor has reached sufficient temperature.
- Close Preheater Valve: Once preheating is complete, close the rapid preheater valve.
- Light Lantern: Slowly open the main fuel valve of the lantern. The mantle should ignite and glow brightly. If not, repeat the preheating process.
