Lift the grill grid to its highest position with the handwheel before lighting your first fire. During the first few sessions, make smaller fires so the firebricks can harden gradually with the heat.
The grill grid itself does not need to be preheated before grilling; it’s ready once your fire gives steady embers. Keeping the grid in full open flames for long periods without food is not good for its lifespan and can cause unnecessary wear.
After each session, let the grill cool completely before cleaning. After the first few grill sessions, wipe each time the ashes by hand into the open spaces between the firebricks until they are nicely filled.
