Position the two bottom supply vents on the grill body and the two top exhaust vents on the grill lid to 100% open. Open the cooking grates and place the adjustable fire grates at the roasting / baking position. This is the middle position just above the main fire grate, and below the grilling position. Place one full chimney of lump charcoal on the adjustable grates and light it using a tumbleweed fire starter or a paraffin cube. Once charcoal has ashed over, using heat-resistant gloves, pour charcoal along either the right or left side of the adjustable fire grate.
Return the cooking grates to the closed position, and close the grill's lid. Monitor the Shokunin temperature and adjust the vents when the temperature gets to approximately 85% of the desired cooking temperature. For baking this is usually around 350°F and for roasting the temperature is generally about 400°F. Those temperatures may change slightly depending on the recipe, and only require slight adjustments to the exhaust vent(s) to achieve.
