Applicable Burners: Svea 123 New Model, Optimus 8R, Optimus 99, etc.
Precautions for Use: Due to the nature of self-evaporating burners, the tank must be more than half-filled with fuel to quickly build pressure. Insufficient fuel may result in poor vaporization or internal combustion. Please always keep this in mind.
** Since burners directly preheat the fuel tank (e.g., Svea 123, Forevus, etc.), the heat from the tank can cause the filler port to harden quickly, so replace the fuel tank frequently.
