❒ Prepare the fuel quantity actually needed to load the thermal storage.
➥ The fuel quantity actually required is determined by the difference of the fuel
quantity shown on the display and the current remaining fuel in the fuel-loading
chamber.
❒ The optimal time for adding fuel is when the basic firebed is achieved.
➥ A firebed is “basic” when it reaches the top row of holes in the cladding.
❒ Open the fuel loading door, add the prepared fuel quantity, then close the fuel
loading door and insulated door again.
