Features
- Two true zones in one fire box: splits the charcoal area so one side cooks direct and the other indirect at the same time (Primo).
- Uses less charcoal on small cooks: Primo says the divider conserves natural lump charcoal when you only need part of the grill.
- Heavy cast iron: Primo describes it as a heavy cast iron divider.
- Sear and smoke together: Primo's owner's manual suggests cooking directly over the heat on one side and smoking on the other.
- Held in the oval fire box: Primo's owner's manual describes slots in the Oval fire box that secure the firebox divider.
- XXL-sized: made for the Oval XXL 500 and its 20.5 x 26.5 in. cooking grid.

Installation planning
- Fit: this divider is for the Oval XXL 500. Primo warns it may not fit certain pre-2015 charcoal grates; contact us with your grill's age before ordering. Primo's warranty does not cover unauthorized parts.
- Placement: Primo's owner's manual describes slots in the Oval fire box that secure the firebox divider. Primo publishes no separate installation sheet for the divider.
- Two-zone fire: Primo's Quick Start Guide calls for half a fire box of charcoal for two-zone cooking and a full fire box for smoking and searing temperatures.
- Lighting: use only natural lump charcoal, lit with a fire starter cube or two, a chimney starter or an electric starter with the dome open; wait 5-10 minutes for embers. Never use lighter fluid; Primo says it is absorbed by the ceramics and gives food a fuel taste.
- Grill placement: Primo's XX-Large spec sheet asks for 12 in. of clearance behind the grill so it opens properly and at least 2 in. around the outside of the grill.
Care: Primo's warranty maintenance asks owners to clean ash from cast iron grates and to clean cast iron cooking surfaces after each use; lack of maintenance is not covered.
