Description
The Primo Ceramic Heat Deflector Plates for the Oval XXL (PG00323) are the pair of ceramic plates that turn Primo's largest kamado, the Oval XXL 500 PGCXXLH, into an indirect cooker. Primo sells them 2 per box and says to use them together with the heat deflector racks to convert the Primo Oval into an oven, roaster or smoker. Primo's brochure says the rack holds the heat deflector plates in the grill, which allows indirect cooking.
The plates need the XXL rack: the heat deflector rack / drip pan rack for Oval XXL PG00375, sold separately. The XXL has 500 sq. in. of main cooking area on a 20-1/2 x 26-1/2 in. grid, 850 sq. in. with Primo's optional racks, and a 151 to 850°F+ range (Primo XX-Large spec sheet). Primo's Quick Start Guide lists the indirect one-zone setup for baking, roasting and smoking as the one that needs heat deflectors or racks.
Plan ahead: these plates are sized for the XXL only; other oval sizes have their own plates, listed below. Primo notes this ceramic item may have a longer-than-normal lead time, and it does not publish the plates' dimensions or weight. To split the XXL fire box into a direct and an indirect zone instead, see the XXL firebox divider PG00371.

Features
- Oven, roaster or smoker: Primo says the plates, used with the heat deflector racks, convert the oval grill for indirect cooking.
- Two plates per box: Primo packs the XXL set as 2 pieces.
- Sized for the XXL 500: made for Primo's largest oval, with its 20-1/2 x 26-1/2 in. grid.
- Low-and-slow setups: Primo's owner's manual recipes use indirect setups from about 225-250°F up to about 350°F.
- Pairs with the XXL drip pan rack: the PG00375 rack that holds the plates is also Primo's XXL drip pan rack.

Setup and use
- Confirm the size: these plates are for the Oval XXL 500. Primo's warranty does not cover unauthorized parts, so match the part to your grill before ordering.
- Set up indirect cooking: place the XXL heat deflector rack in the grill to hold the two plates, as Primo describes for its plates and racks. Primo does not publish a separate diagram for the XXL set, so ask us if you are unsure.
- Handle with care: Primo's owner's manual warns that ceramic will break if dropped, and to use caution with any hot item and keep children away while cooking.
- Fuel and lighting: use only natural lump charcoal, lit with a fire starter cube, a chimney or an electric starter with the dome open. Never use lighter fluid; Primo says it is absorbed by the ceramics and gives food a fuel taste.
- Temperature control: Primo's Quick Start Guide notes that it is easy to raise the temperature and hard to bring it down, so approach your target gradually; for smoking, start a small fire and use only the daisy wheel holes on the top vent.
- Grill placement: the XXL needs 12 in. of clearance behind it so the lid opens properly and at least 2 in. around the outside (Primo XX-Large spec sheet).
Care: Primo does not publish separate care instructions for the plates. Primo says tiny surface cracks (crazing) in its ceramics are normal; if chunks of ceramic break off, contact Primo (owner's manual).
