Fire Magic Echelon Diamond Grill Review: Smart Luxury Performance 2026
Fire Magic Echelon Diamond E790i:
The Smart Luxury Built-In Grill That Redefines Precision
If you have been searching for an honest Fire Magic Echelon Diamond grill review, you are in the right place. The Fire Magic E790i grill is the most technologically advanced grill we have ever carried at Best of Backyard. At a current sale price of $9,810.00 through July 31, 2026 (down from $10,900.00 MSRP via the Fire Magic America 250th Anniversary Promo), this 36-inch built-in powerhouse delivers 90,000 BTUs of main burner power, a patented Diamond Sear cooking grid system, a full WiFi and Bluetooth digital touchscreen control panel, a built-in Magic View hood window, an integrated smoker basket, and a rear infrared rotisserie burner, all proudly designed, engineered, and built in the USA. This is the best 36 inch luxury built-in grill we carry and it is on display at our Best of Backyard showroom in Riverside, CA.
At the core of the Fire Magic E790i grill are three cast stainless steel E-burners with 1/4-inch thick walls, each delivering 30,000 BTUs for a combined 90,000 BTUs across a 792 sq. in. primary cooking surface and 288 sq. in. warming rack for 1,080 sq. in. total. The patented Diamond Sear cooking grids feature a flat-top trapezoidal design that covers more than half the total cooking surface, delivering faster heat transfer and steakhouse-quality sear marks on every cut. Above the burners sit 16-gauge stainless steel flavor grids that vaporize drippings instantly for added smoke flavor while protecting the burners from grease and flare-ups. This is what makes the Fire Magic built-in gas grill lineup stand apart from every other luxury grill we carry.
What makes the Fire Magic Echelon Diamond grill review story unique is the digital control system. The smart grill with digital display features a state-of-the-art under-glass touchscreen control panel with 4-zone temperature monitoring, an included meat probe for internal food temperature tracking, and full WiFi and Bluetooth connectivity to the Fire Magic smartphone app for remote temperature monitoring. Backlit comfort-grip knobs shift from blue to red the moment gas is flowing, giving you a clear visual safety indicator at any time of day or night. The showroom unit also includes the optional left-side infrared sear burner and the Magic View window embedded in the hood — two add-ons included at no extra charge on all Echelon Diamond grills.
The Fire Magic E790i grill comes loaded with features that justify its position as the best 36 inch luxury built-in grill in our showroom. The 13,000 BTU rear infrared rotisserie burner uses a stainless steel mesh encased ceramic system for efficient, even rotisserie heat and includes a stainless steel protective cover when not in use. The rotisserie kit is included standard at no additional cost.
A charcoal and smoker basket is also included standard on all Echelon Diamond grills, allowing you to add real wood or charcoal for authentic smoke flavor without a separate smoker. The push-to-light hot surface ignition system requires a 120V AC power source and fires the grill instantly and reliably in any weather condition. Flash tubes provide a backup manual ignition method across all burners. The double-lined spring-assisted hood opens 90 degrees for full access and efficient heat exhaust. Dual angled interior halogen lights illuminate the entire 1,080 sq. in. cooking layout for precise nighttime grilling. The unit in our Best of Backyard showroom is the Natural Gas configuration.
The Fire Magic built-in gas grill E790i is backed by a tiered warranty that reflects the quality of each component. Lifetime on cast stainless steel burners, Diamond Sear cooking grids, and stainless steel housings. 15 years on brass valves, inner liners, manifold assemblies, and backburner assemblies excluding ignition parts. 5 years on flavor grids and infrared burners. 3 years on all other grill components excluding ignition and electrical. 1 year on ignition systems, electronic components including lights and thermometers, and accessories. Labor is included for 2 years up to $120 from the original purchase date. The E790i measures 37" wide, 27" high, and 23.5" deep, with a cutout of 37" wide, 11.5" high, and 23.5" deep, and weighs 275 lbs. Fire Magic grills have been proudly crafted in the USA since 1937.

Fire Magic Echelon Diamond Grill Review:
Pros and Cons
- 90,000 BTUs across three cast stainless steel E-burners — the highest main burner output of any grill in our entire showroom series. Each burner is cast from 1/4-inch thick 304 stainless steel, weighing up to 12 lbs each, delivering instant searing temperatures that buyers consistently praise for holding heat without dropping under load
- Patented Diamond Sear cooking grids with a flat-top trapezoidal design cover more than half the total cooking surface area for steakhouse-quality sear marks, faster heat transfer, and a non-stick matte finish. No other grill in our showroom has a patented cooking grid design of this caliber
- Smart digital touchscreen control panel with 4-zone temperature monitoring, included meat probe displayed on the same screen, and WiFi and Bluetooth connectivity to the Fire Magic smartphone app. The most advanced digital control system of any grill we carry at Best of Backyard
- Magic View ceramic glass window embedded in the hood — the only grill in our showroom with this feature. Monitor food progress without lifting the hood and losing heat. Particularly valuable during long rotisserie cooks and smoking sessions
- Hot surface ignition fires instantly and reliably in wet, cold, or windy conditions without batteries. Flash tube crossover backup provides manual ignition across all burners if the primary system ever needs service. Confirmed as one of the most reliable ignition systems in our showroom
- 16-gauge stainless steel flavor grids sit above the burners and vaporize drippings instantly, sending aromatic smoke back up into the food for enhanced flavor on every cook while protecting the burners from grease and minimizing flare-ups
- Rotisserie kit and 13,000 BTU rear ceramic infrared backburner included standard at no extra cost. The stainless steel mesh encased ceramic backburner system provides efficient, even rotisserie heat and includes a protective stainless steel cover when not in use
- Charcoal and smoker basket included standard on all Echelon Diamond grills at no additional charge, allowing real wood or charcoal smoke flavor without a separate smoker or aftermarket accessory
- Dual angled interior halogen lights and backlit comfort-grip control knobs that shift from blue to red when gas is flowing. Night-time grilling is fully supported and the knob safety indicator is genuinely useful during multi-zone cooks
- Industry-leading tiered warranty including lifetime coverage on cast stainless steel burners, Diamond Sear cooking grids, and stainless steel housings. Backed by RH Peterson Co., a brand that has been manufacturing premium American grills since 1937
- Made in the USA in City of Industry, Southern California by skilled craftsmen at RH Peterson Co. Every Fire Magic product is designed, engineered, and hand-built using commercial-grade 304 stainless steel to the absolute highest quality standards
- Currently on sale at $9,810.00 through July 31, 2026 via the Fire Magic America 250th Anniversary Promo, down from the $10,900.00 MSRP. This is the strongest Fire Magic promotional discount currently active
- Premium price at $9,810.00 on sale ($10,900.00 MSRP) is the highest-priced grill in our showroom. This is a serious financial investment that prices out casual buyers and requires commitment to outdoor kitchen cooking at the luxury level
- Heat management learning curve at high output. Because the Fire Magic E790i grill delivers 90,000 BTUs of raw power, multiple buyers note a learning curve is required to avoid overcooking food before getting familiar with the temperature controls and heat zones
- Digital tech complexity for traditional cooks. The touchscreen panel, smartphone app, WiFi and Bluetooth connectivity, and 4-zone monitoring take time to learn and configure. Buyers who prefer a simple turn-and-grill experience may find the smart grill with digital display system overwhelming at first
- 275 lbs requires professional installation. This is a heavy and immobile grill that requires careful structural planning during your outdoor kitchen island build. Professional help is strongly recommended for installation
- Occasional flare-ups at maximum heat with fatty cuts. While the flavor grids minimize flare-ups effectively, cooking highly fatty cuts at absolute maximum temperatures can still trigger occasional flare-ups due to the sheer heat output of 90,000 BTUs
- Electronic components carry only a 1-year warranty. After the 1-year coverage expires, replacing the digital display, lights, or thermometer components can be costly. Plan for this as part of long-term ownership of a smart grill with digital display at this price point
- 120V AC power required for the hot surface ignition system, interior halogen lights, and digital control panel. This needs to be planned for and budgeted during your island installation before the grill arrives
How Does the Fire Magic Echelon Diamond
Score in Every Category?
Fire Magic Echelon Diamond Overall Score
The Fire Magic Echelon Diamond grill review lands at 4.2 out of 5. This is the most feature-complete and technologically advanced grill in our entire showroom series. The Fire Magic E790i grill earns its score through 90,000 BTUs of main burner power, patented Diamond Sear cooking grids, a digital 4-zone touchscreen with WiFi and Bluetooth, the only Magic View hood window in our showroom, rotisserie and smoker basket both included standard, and 85 years of American manufacturing excellence behind every weld. For the buyer who wants the absolute pinnacle of outdoor cooking technology, this is the best 36 inch luxury built-in grill we carry.
The honest trade-offs are worth knowing. The 90,000 BTU output requires a real learning curve for precise heat management. The digital tech takes time to master. Electronic components carry only a 1-year warranty at a $10,900.00 MSRP price point. And at 275 lbs it requires professional installation planning. But as a Fire Magic built-in gas grill backed by the industry's most respected warranty and the most complete feature set we have ever reviewed, the E790i makes a compelling and clear case. Come see it at our Best of Backyard showroom in Riverside, CA.
