Firebox, fire ring, protector stone and grate

Cracks, and changing the firebox

The 2019 FAQ and the manual. The Junior's firebox is one piece: there are no segments to swap.

1. Keep using a cracked firebox or fire ring. Stress cracks act as expansion joints, are not a defect, rarely spread and do not affect the cook (2019 FAQ).
2. To change a broken firebox (201053-J), lift out the grid, the charcoal grate and the fire ring gently.
3. Lift the old firebox out and set the new one in with its front notch exactly at the draft door.
4. Check the protector stone (201054-J) lies flat on the base floor inside it (protector stone).
5. Refit the fire ring with its recess exactly in front of the chip-feeder flap.
6. Lay the charcoal grate back on the firebox ledge, then the grid.

Check or fit the protector stone

The manual: "Junior only: put the protector stone in the firebox on the floor of the body." It keeps the underside from getting too hot.

1. With the grill cold, lift out the grid, the charcoal grate, the fire ring and the firebox (deep clean).
2. Lift the protector stone out and look for breaks.
3. Brush the base floor under it. No water (the manual).
4. Lay the stone, or a new one (201054-J), flat in the middle of the base floor.
5. Refit the firebox, fire ring, grate and grid in the manual's order.
