Description
The Primo Cast Iron Firebox Divider for Oval Large (PG00344) is the Large size of Primo's heavy cast iron divider. Primo says it "allows you to split the fire box area to create two distinct cooking zones," so you can cook direct and indirect at the same time, and that it conserves natural lump charcoal on smaller cooks. Primo's owner's manual puts it simply: add a firebox divider and cook directly over the heat on one side and smoke on the other, or use it to cook on one small section of the grill.
It is made for the Primo Oval Large 300 PGCLGH grill head and the All-In-One Oval Large 300 PGCLGC. The Oval Large 300 has a 15 x 22 in. cooking grid with 300 sq. in. of main cooking area (495 sq. in. with the optional rack system), per Primo's Large spec sheet. Other sizes use their own dividers: Oval XL PG00334, Oval Junior PG00314 and Oval XXL PG00371. Primo does not list a divider for the Round. For indirect cooking on the Large, see the Large heat deflector racks PG00316 and ceramic heat deflector plates PG00326.
Plan ahead: Primo warns the divider may not be compatible with certain pre-2015 charcoal grates and asks you to contact it before purchasing if you are unsure, so tell us your grill's age or serial number before you order. Primo does not publish the divider's dimensions or weight.
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 says the bottom grate sits at the mid-base of the fire box with its divider slots facing up, and those slots secure the Oval firebox divider.
- Oval Large-sized: made for the Oval Large 300 and its 15 x 22 in. cooking grid.

Installation planning
- Fit: this divider is for the Oval Large 300. 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 has you set the bottom grate at the mid-base of the fire box with the divider slots facing upward; those slots secure the Oval 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 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.
