The Primo Oval G 420, 21,000 BTU - Head (for Built-In Applications) transcends standard gas grills by integrating a premium-grade ceramic shell. Unlike metal gas grills that radiate high amounts of heat and pull the moisture out of food, the ceramic shell of the Primo Oval G 420 acts as an insulator to retain more heat and preserve the natural moisture and oils of the food.
The assembled grill features premium grade ceramics, 304 stainless steel cooking grates, burners, flavor grids, exterior, and components. The cart features brushed aluminum handles with a powder-coated steel exterior and locking casters. Every Primo is built for years of use and enjoyment.
With two low burners and two high burners, you have the flexibility to smoke at 220°F or reach grilling temperatures in less than five minutes. Available as “grill head only” for use on an outdoor island or with a Primo Cart.

Select from multiple installation options to find the best fit for you! Choose from a Primo cart, cradle, table, or All-In-One package to complete your grill purchase. The All-In-One package comes with the grill head, an ergonomic handle, cradle stand, side tables, ash tool, and grate lifter.


Everything you need to get started All In One Box. The Primo All-In-One Series was developed with convenience in mind. The vision behind the product was to offer a selection of grills that are ready to grill out of the box after a few minutes of easy setup and assembly. This series also offers a cost-effective avenue for Primo customers to get a bigger “bang for their buck” without breaking the bank. All four models are the same great ceramic grills we offer as stand-alone products with added accessories to provide a ready-to-grill experience out of the box. A Primo All-In-One Grill can be assembled in minutes and ready to cook. Once assembled just add whole lump charcoal, light, and grill your favorite food.

What makes the best grill?

Grill Features

  • Patented Oval Design. The Primo Oval offers true two-zone simultaneous direct and indirect cooking. That’s a fancy way of saying that you get two very distinct cooking zones. Almost like using a grill and an oven at the same time. Grill steaks on the direct side and roast seafood or vegetables on the indirect side. No round grill offers so much cooking versatility. The Reversible Cooking Grid, Heat Deflector Plates, Extension Racks, and other accessories allow you to create more than 69 different cooking configurations. No other grill offers so much versatility.
  • Premium-Grade Ceramics. Primo ceramic grills are composed of a proprietary blend of natural materials to make the highest grade of ceramics available for superior heat and moisture retention. Combined with quality-controlled production processes and an unmatched firing temperature, our ceramics are significantly more efficient than other ceramic grills. Use less fuel, reach your desired temperature faster, and reduce your cooking time with Primo.

Cooking Configuration

Primo Ceramic Grills can be used as a grill, oven, roaster, or smoker. Cool air is drawn into the bottom vent, then heated by the charcoal. The heated air convects around the food before exiting the top vent. The ceramic shell retains more heat than metal grills and helps food retain more of its moisture than conventional grills.
Grill mouthwatering steaks, bake authentic wood-fired pizza, roast a turkey, or smoke a beef brisket to tender perfection. Any food and recipe can be cooked on a Primo. The possibilities are endless.

Grilling & Searing. Use this configuration for grilling meat such as steaks, chicken breasts, or any foods that benefit from cooking directly over the charcoal fire.

Fill the firebox with natural lump charcoal. Use the vents to control airflow for perfect grilling temperatures. The shape of the ceramics creates convection and an even grilling experience that locks moisture into the food.

Grilling & Roasting. Use direct and indirect cooking zones to grill meat on the direct side, while roasting tender foods like seafood and vegetables on the indirect side.

Insert the cast iron firebox divider. Fill one side of the firebox with natural lump charcoal. Create two distinct cooking zones using a heat deflector rack and heat deflector plate. This allows you to sear a steak over direct heat while roasting tender vegetables or seafood over indirect heat.

Baking, Roasting & Smoking. Use this configuration for indirect cooking such as an oven or smoker. Cook at low to medium temperatures for baking pizza or smoking meat. (Heat Deflectors/Racks required).

Fill the firebox with natural lump charcoal. Using two deflector racks and heat deflector plates forms a central zone for full indirect cooking. Bake bread and cakes at 350°F, roast chicken to tender perfection at 425°F, or smoke your favorite BBQ low and slow at 225°F. You can raise the temperature even higher to 550°-650°F creating a wood-fired pizza oven...

  • Once I decided on buying this particular model, I did exhaustive research on several different vendors and settled on the Grill Collection, because of their amazing customer service, response time, and unbelievable price match. Jerome was absolutely amazing to work with, and I very much look forward to ordering the rest of my appliances and equipment for my outdoor kitchen space in the coming days. The customer service from Grill Collection is unmatched by any of the other companies I have spoken with. Someone is always right there to step in and answer a question for you. After sending an email inquiry, I received a response in less than two hours. The delivery process was flawless. Once I was notified the grill had shipped, I was immediately given my tracking number, and within days I was contacted by the carrier to set up delivery. The delivery process was incredibly smooth, they placed the grill exactly where I requested it, they inspected it with me, and I couldn't be happier. From shipping to arrival, it was less than a week before it arrived to ship cross country. If you are in need of anything for your backyard space, Grill Collection is the place to buy it!!!

  • The primary reason I chose Grill Collection is because they had the item I wanted in stock where other sites selling the same item wasn't available till the end of the year. I had already purchased the unit from another website and I really didn't want to go through the hassle of trying to get a refund and then waiting for the refund and then turning around and purchasing another unit somewhere else. I purchased the unit from the other website previously because their website said I would receive the unit by the end of July. When the transaction was completed and they finally received the notice from the manufacturer the shipping and receiving dates changed. It was now shipping by Nov 27th and receiving by Dec 2nd, basically I would be waiting half a year to receive my order so that wasn't going to work. By then summer is over!!! Second and most important reason I chose Grill Collection is because of Erica's awesome customer service, many many thanks to Erica for her service. She finalized my decision based on many factors besides the fact that I'm an Amazon Prime Member and paying through Amazon would work for me as well but also these reasons: 1. Prompted to serve customers need. 2. If I had problems with my order I know it wouldn't take hours to get s hold of customer service 3. Talking to a live representative vs machine 100% 4. Piece of mind knowing that I'm doing business with a company that's 100% behind my customer satisfaction with guaranteed product availability and delivery, makes me want to purchase only from them. 5. Lower price definitely!!! 6. 👍😇😉😆 Thank you Can't wait to get my grill!!

  • I had a fantastic experience with the Grill Collection. First when I was shopping online for the Napoleon Prestige 500 grill you had the lowest price online. I was shopping late on a Saturday night and was not expecting anyone to be available to chat to answer some questions but someone was available (I forget his name) and he answered my questions so I placed the order that day. Lastly I know most of these were taking 4 weeks to ship but you were able to ship mine in under 3 weeks, sooner than expected. Post order support was great as well. You should be very proud of the service you provide, few companies have people online available to chat at on the weekends and shipping sooner than expected is rare!
