Primo Oval X-Large Charcoal Kamado Grill Head

Patented Oval Shape, Premium Made-in-USA Ceramics, Built-In Outdoor Kitchen Centerpiece, 400–680 sq. in. Cooking Matrix, True Dual-Zone Direct/Indirect Engine

Unlock the definitive pinnacle of fuel efficiency, high-mass heat retention, and large-scale kamado cooking with the Primo Oval X-Large Charcoal Grill Head (Model SKU: PRI-BI-400 / PGCXLH). Proudly handcrafted and factory-tested right here in the USA since 1996, Primo stands as the undisputed champion of premium ceramic design thanks to its patented oval geometric profile. Unlike traditional round kamados that crowd your fuel bed and push food toward a central hotspot, Primo's elongated footprint maximizes usable horizontal cooking space—giving outdoor chefs the unique ability to execute true dual-zone grilling with a high-intensity open-flame sear and a gentle, indirect convection smoke running simultaneously under the same hood.

Explicitly configured as a Standalone Standalone Grill Head, this 200-pound thermal titan is engineered to drop flawlessly into custom outdoor kitchen islands, premium stone masonry enclosures, or high-end built-in patio cabinetry. From holding a rock-steady 151°F low-and-slow ambient temperature for overnight Texas briskets to rocketing past 850°F+ for authentic stone-baked artisanal pizzas, the Oval XL 400 delivers a massive cooking footprint backed by an industry-leading limited lifetime manufacturer warranty.

Patented Oval Geometry & Multidimensional Thermal Engineering

• The Power of the Primo Oval Shape: Engineered specifically to bypass the core spacing limits of traditional round cookers. The elongated profile provides an extensive 400 square inches of primary workspace, expanding up to 680 square inches by adding a pair of secondary cooking levels—room enough to comfortably handle 20 burgers, 12 thick steaks, 10 racks of ribs, or 2 massive whole holiday turkeys.

• True Dual-Zone Convection Cooking: Primo's oval canvas effortlessly divides your cooking fire. Bank lump charcoal to one side for direct steakhouse branding marks while keeping the opposite zone completely clear of active flames to bake delicate side dishes or reverse-sear prime cuts.

• Premium Shock-Resistant US Ceramics: Hand-crafted using a proprietary, high-density natural ceramic matrix and finished in a scratch-resistant, weather-hardened black porcelain glaze. This thick-walled shell locks in ambient moisture and intense convection currents like an industrial kiln, keeping meats incredibly juicy while drastically reducing charcoal consumption.

• The Highest Dome Clearance Available: Built with an extra-tall sitting dome hood profile that provides unmatched vertical workspace clearance. This design allows you to roast multiple whole chickens, multi-tier poultry racks, or large holiday turkeys standing completely upright without crowding the lid.

Heavy-Duty Mechanical Controls & Built-In Infrastructure

• Advanced Air-Lift Hinge Counterbalance: Outfitted with a premium mechanical hinge track assembly that eliminates heavy lifting. The high-tension springs neutralize the heavy ceramic hood weight, reducing the effort needed to crack the dome by 70% while guaranteeing excellent seal tightness when closed.

• Reversible Split Stainless Steel Grates: Arrives with premium split 6mm stainless steel cooking grids. These multi-position grates can be flipped over to adjust their proximity to the glowing coals, providing immediate adaptation between flash searing and gentle heat boundaries.

• Presurized High-Temperature Gaskets: Equipped with a premium Nomex-based commercial high-temperature gasket system designed to handle continuous thermal stress. This seal outlasts traditional felt gaskets, preserving a pressurized vacuum environment to protect fuel consistency.

• Precision Airflow Damper Layout: Regulated by a 6-position cast aluminum top chimney cap with an integrated rain shield and a sliding stainless steel base draft vent door. This control network lets you dial in fine-tuned internal temperatures within minutes.

Technical Specifications Summary

Essential Requirements for Built-In Installation

Because this standalone model is intended for custom outdoor installation, please observe the following physical guidelines during your outdoor kitchen build:

• Thermal Clearance Feet: Never place a ceramic grill head directly onto a combustible or non-combustible counter surface without structural airflow beneath the unit. A set of Primo Ceramic Grill Feet (Part #PG00305) must be positioned underneath the base to provide vital thermal clearance and prevent heat transfer.

• Rear Clearance Mapping: The advanced hinge system requires at least 12 inches of clearance behind the grill to open properly without hitting backwalls or stone backsplashes.

• Air Supply Accessibility: Ensure the lower sliding stainless steel draft door remains fully accessible and free of structural blockages to maintain proper convection airflow currents.
