The smallest built-in grill in Cal Flame's G-Series: three 15,000 BTU burners (45,000 BTU total) and 600 sq. in. of cooking area, starting at $1,584. It's the lowest-priced Cal Flame built-in we carry and fits the narrowest island opening, a 23 3/8" cutout, so it's the pick for small patios and for cooking for two to four people without paying for capacity you won't use.

Why Choose the G-Series 3-Burner

  • Fits where bigger grills won't: 24 1/2" wide overall, so it works in compact islands.
  • Three separately lit burners: each is 15,000 BTU with its own ignition, so you can run one zone hot for searing and another low to keep food warm.
  • Upgrade it later: burners can be swapped for a Sear Zone burner or a smoke tray (sold separately).
  • Long warranty on the parts that matter: 10 years on structure, stainless steel burners and V-grates; 3 years on flame tamers and the warming rack; 1 year on gas valves and other components. Residential use.
  • A known fit: it's the same grill that comes standard on Cal Flame's Patio Series islands (Kona Q, Maui Q and Kauai Q).

Who It's For and How It Compares

  • Best for: small patios, first outdoor kitchens and tighter budgets.
  • vs. the G-Series 4-Burner: the G-4 adds a fourth burner (60,000 vs. 45,000 BTU) and 800 vs. 600 sq. in. of cooking area for $302 more. Choose the G-3 if you rarely cook for more than a few people.

Why the price works: from $1,584 you get a Cal Flame G-Series grill with the same 10-year warranty on the main parts as the larger models.

Key Features

  • 3 burners, 15,000 BTU each (45,000 BTU total)
  • 600 sq. in. of cooking area
  • Porcelain-coated cast iron burners for durability and even heat
  • Runs on liquid propane; natural gas conversion kit sold separately
  • Built-in installation into a Cal Flame outdoor kitchen island

The Brand

About Cal Flame

Cal Flame has spent more than 44 years designing and manufacturing outdoor kitchen equipment from Pomona, California, growing into an award-winning name in built-in grills, islands, and backyard cooking systems. Every grill blends heavy-gauge stainless steel construction with performance features developed and tested in-house, backed by ETL and CE safety certifications.
  • Signature V-Shaped Grates

    Cal Flame's exclusive V-patterned grates channel grease away from the flame and leave the deep sear marks the brand is known for.

  • 304 & 430 Stainless Steel Construction

    Grill bodies and burners are built from marine-grade stainless steel, with heavier-gauge two-layer walls on select series for lasting durability.

  • Cast Stainless Burners, Independently Ignited

    Each burner lights and adjusts on its own switch, so you can run just what you need instead of firing the whole cooktop.

As Featured

“Loaded with great features and constructed from top quality 304 grade stainless steel — very well made with beautiful fit and finish.”

Cal Flame backs its grills with a tiered limited warranty: up to 10 years against rust-through on the frame, burners, and V-grates, 3 years on flame tamers and warming racks, and 1 year on gas valves and other components. Coverage applies to the original purchaser using genuine Cal Flame parts — see your product's manual for full terms.
