TrueFlame 40" Built-In Gas Grill – 5 Burners, Infrared
70,000 BTUs and an Infrared Back Burner — The Centerpiece Grill for Outdoor Kitchens Built to Host
Five burners, full lighting, and rotisserie-ready power for outdoor kitchens that need to feed a crowd.
The TrueFlame 40" (TF40) is a built-in gas grill made for outdoor kitchens that entertain often. #304 stainless steel construction houses five 14,000 BTU cast stainless steel burners (70,000 BTUs total), heat zone separators for multi-zone control, and square stainless cooking grates across an 892 sq. in. surface. A 10,000 BTU infrared back burner adds rotisserie-ready performance, and a full lighting package — halogen interior lights, a full-length exterior LED bar, and backlit knob indicators — keeps the whole grilling surface visible after dark. It's backed by the manufacturer's Gold Standard Lifetime Warranty.
Prefer a slightly smaller footprint with the same rotisserie-ready concept? Compare against the TrueFlame 32" built-in gas grill with infrared back burner.
TF40 Features & Benefits
Built to be the centerpiece of an outdoor kitchen designed for entertaining.
Total BTUs Across Five Cast Burners
Five 14,000 BTU cast stainless burners deliver strong, consistent heat across a wide cooking surface for large gatherings.
BTU Infrared Back Burner
Purpose-built for rotisserie cooking, delivering consistent, even heat for poultry, roasts, and large cuts of meat.
Sq. In. Total Cooking Surface
663 sq. in. of primary grate plus a 229 sq. in. warming rack gives you room to cook and hold food for a full table.
Full Lighting Package
A full-length LED bar, backlit knob indicators, and halogen interior lights keep the entire grilling surface visible after dark.
Separators for Multi-Zone Control
Run mains over high heat while sides finish gently on another zone, across a grill wide enough to do both at once.
Built for Confident, High-Volume Cooking
Square stainless cooking grates increase food contact for bold grill marks, and #304 stainless flame tamers help distribute heat evenly while cutting down on flare-ups. A balanced, multi-position, spring-assisted hood hinge makes lifting the hood smooth even at this size. Piezo and manual flash tube ignition gives you a dependable backup way to light the burners, and the inset, removable cooking tray in the warming rack adds a spot for finishing sauces or holding sides.

- Households that frequently entertain and need real five-burner capacity, not just a wider grill head.
- Cooks who want rotisserie capability built in, not added on later as a separate purchase.
- Anyone who grills regularly after dark and wants visibility across the full cooking surface.
- Outdoor kitchens designed as a true entertaining hub, where the grill is the centerpiece.
