Features
- Patented oval shape: two cooking zones in one grill, so you can sear over the fire and roast or smoke beside it.
- 300 sq. in. main cooking area, 495 sq. in. with racks: Primo rates it for 6 whole chickens, 1 whole turkey, 8 steaks, 12 burgers, 8 racks of ribs or 8 ears of corn.
- 151 to 850°F and up: premium-grade ceramics hold heat for low-and-slow smoking at about 225°F as well as high-heat searing.
- Top damper with daisy wheel and a lower draft door: two air controls for fine temperature adjustment, from smoking to searing.
- Built-in ready: Primo publishes a standard and a hinge-notch cut-out for the Large, so it can sit in an island or outdoor kitchen counter.
- Made in the USA: built by Primo in Poplar Bluff, Missouri.

Installation planning
- Placement: allow 12 in. behind the grill so the lid can open fully, and keep at least 2 in. of space around the exterior surface of the grill.
- Stand: the head weighs about 152 lb. Set it in a Primo cart or table made for the Oval Large, or in a built-in counter. Primo's oval unpacking instructions (PG1000596) call for two adults, one at each end, with one hand under and one behind the grill; never lift it by the hinge assembly, and use a 5 mm hex key to check that both bands are tight before and after first use (do not overtighten).
- Built-in: Primo's Large spec sheet carries the LG cut-out for island and outdoor kitchen installs (grill head only, rear of the grill at the top of the drawing). The standard cut-out (Fig. A) needs a supporting shelf 10-1/4 in. below the countertop surface; the hinge-notch cut-out (Fig. B) sets the grill lower and needs the shelf 13 in. below. Primo says not to scale the drawings, so check the current template against the grill on site before cutting.
- Fuel and lighting: use only natural lump charcoal, a full fire box for searing or smoking and about half for two-zone cooking. Light it with fire starter cubes, a chimney starter or an electric starter with the dome open; after 5 to 10 minutes, when embers form, close the dome and open the draft door and top vent fully. Never use lighter fluid or other combustible liquids, because the ceramic absorbs them and food can taste of fuel.
- Temperature control: when you are within about 25°F of your target, close the top vent to one-third open, wait 1 to 2 minutes, then adjust it in 1/4 in. steps (each step can move the temperature up to about 25°F). For grilling keep the draft door fully open; for roasting set it about one-third open. For smoking at about 225°F, start a very small fire, set the draft door to about a 1 in. opening at 200°F and use only the daisy wheel holes on the top vent. It is easy to raise the temperature and hard to bring it down.
- Cooking setups: direct one-zone grilling and searing, two-zone grilling and roasting, or indirect one-zone baking, roasting and smoking with heat deflectors or racks.
- Reusing charcoal: lump charcoal can be used 2 to 3 times; stir the ash through the fire grate with an ash tool and add about 30% new charcoal.
Care: Primo's warranty requires regular maintenance: clean the ash from the cast iron grates to prevent buildup, clean the cooking grates and cast iron surfaces after each use, and check and tighten the band bolts several times a season and after high-heat cooks. Surface rust, fading and blemishes on metal parts are not covered unless they cause a part to fail.
Warranty
Primo Ceramic Grills warrants the grill to the original purchaser: a limited lifetime warranty on all ceramic parts; a limited 5-year rust-through warranty on all metal parts except cast iron; a limited 1-year rust-through warranty on all cast iron parts and all other parts and accessories unless stated otherwise; and a limited 30-day warranty on felt gaskets and thermometers.
Conditions: the grill must be installed according to Primo's instructions, with access for service, and you keep a bill of sale or payment record. Replacement parts ship at the purchaser's expense, and the defective part must be disposed of once the replacement arrives. Not covered: damage from use, misuse, improper installation or storage, unauthorized service or parts, lack of maintenance, removal and reinstallation, service calls, labor, travel, diagnostic and freight charges, and metal rust, fading or oxidation that does not stop the grill from working. Claims go through your dealer, with the model number, serial number and proof of purchase; international claims are not accepted. Full terms are on Primo's warranty and parts page.
