80,000 BTUs Across Four Cast Stainless Burners — The TRL Pro 40 Is the Flagship Built-In for Serious Outdoor Cooks
The TRL Pro 40 puts 80,000 BTUs from four cast stainless burners, a 15,000 BTU infrared rear burner, and 877 square inches of cooking surface into one ETL-certified, 304 stainless built-in.
Four 20,000 BTU cast stainless U-tube burners put 80,000 BTUs across four genuinely isolated heat zones — stronger per burner than the Quest Series, with the temperature recovery to match. The 15,000 BTU infrared rear burner powers the included 40 lb-capacity rotisserie kit for whole-bird and large-roast cooking. Over 876 square inches of total cooking surface means steaks, sides, and rotisserie run simultaneously, nothing waiting. Easy-clean ceramic briquette trays and stainless heat-zone separators keep each zone steady. LED bezel indicators, halogen interior lights, and Flame Thrower ignition make it as practical after dark as at noon. Drops into a 38½" × 20¾" × 9⅜" cutout. 304 stainless throughout, ETL certified, backed by Summerset's Gold Standard Lifetime Warranty.
What Separates the TRL Pro 40 From Every Other Grill at This Output Level
The TRL Pro 40 doesn't just add a fourth burner — it raises the ceiling on what a 40-inch built-in can do, with more BTU per burner than the Quest series and a total output that supports true four-zone cooking without any zone competing with another.

20,000 BTU
Per Burner — Cast Stainless, Not Standard Steel
Each of the four main burners is cast stainless steel rated at 20,000 BTU — stronger per burner than the Quest Series and built from a denser alloy that resists warping under sustained high-heat use. You feel the difference on preheat time, on heat recovery when cold food loads the grates, and on the precision of each zone's low end.
80,000 BTU
Total Main Burner Output — Four Independent Zones
80,000 BTUs across four stainless heat-zone separators gives you four genuinely isolated cooking temperatures that don't bleed into each other — sear on one end, roast in the middle, warm on the other, rotisserie running behind, all simultaneously without any zone affecting another.
15,000 BTU
Infrared Rear Burner for Professional Rotisserie
The rear infrared burner bathes the spit in radiant heat from behind — even, intense, and contact-free — basting a whole turkey, a bone-in prime rib, or a leg of lamb in its own juices as it turns. The included 40 lb-capacity motor handles the largest cuts you'd realistically put on a residential rotisserie.
877 in²
Total Cooking Surface — Feed a Crowd, Not a Batch
Over 876 square inches of total cooking surface including the warming rack gives you space to run a full multi-course spread simultaneously — proteins on the primary surface, bread and sides on the warming rack, rotisserie engaged at the back — without anything waiting for its turn.
304 SS
Commercial-Grade Construction, Start to Finish
The firebox, hood, handle, grates, and burners are all 304 stainless — the alloy used in commercial kitchens and professional outdoor installations for its corrosion resistance and structural integrity under sustained heat cycling. The double-lined, spring-assisted hood adds a layer of protection against exterior heat discoloration.
ETL Certified
Independently Tested for Safety and Performance
ETL certification means an independent third party has tested this grill against established safety standards — an important credential when you're building a permanent island installation and need to confirm the appliance meets code requirements for combustion and gas handling.

Deep Dive — TRL Pro 40›
Ceramic Briquette System + Four-Zone Separators — Consistent Heat Across Every Inch
Under the grates, the easy-clean ceramic briquette trays span the full cooking surface. They absorb heat from all four burners and re-radiate it evenly, eliminating the cold zones that form at the edges or between burners on large grills without this system. They also vaporize drippings on contact, generating smoky flavor that adds to the result of every cook. Stainless heat-zone separators sit alongside the briquettes to maintain true thermal isolation between zones, so a low-temperature zone on one side doesn't drift upward from bleed-through heat. When the session ends, the trays slide out for a quick clean rather than a deep scrub of the burner components.
LED Bezel Status, Halogen Interior, and Flame Thrower Ignition — Built for Round-the-Clock Sessions
Each of the four control knobs has a backlit bezel that glows white on standby and shifts to red the moment that burner fires — so you have an instant visual read on all four zones without leaning over a hot grill. Halogen interior lights flood the cooking surface for clear visibility at any hour. Flame Thrower ignition starts every burner reliably without external power, and manual flash tube backup provides a failsafe if the main ignition is ever unavailable. The spring-assisted double-lined hood opens smoothly, stays open, and retains heat more consistently during covered cooking — and the integrated analog thermometer lets you monitor hood temperature without lifting the lid during a long roast.
Optional 20,000 BTU Drop-In Infrared Sear Burner — Steakhouse Temperatures on Demand
The TRL Pro 40 is compatible with the Summerset Drop-In Infrared Sear Burner for the TRL Pro Series, sold separately. It replaces any one of the four main burners with a dedicated infrared searing zone at 20,000 BTU — generating surface temperatures that build a deep, caramelized crust on a steak in seconds rather than minutes. If high-heat searing is central to how you cook, contact us for details on this upgrade before your island is built.
Who It's For — The Deck & Den Take›
The Deck & Den Take — The TRL Pro 40 is the grill we recommend when someone wants the absolute performance ceiling in a built-in without stepping into a custom or luxury category. Four cast stainless burners at 20,000 BTU each isn't just a number — it's a meaningful difference in how the grill behaves under load, how well it holds temperature when a cold rack of ribs or a full brisket comes on, and how low the low end actually goes for a delicate braise or a fish fillet. Add 877 square inches of total surface, four isolated heat zones, and a 15,000 BTU infrared rotisserie, and this is a grill you genuinely never outgrow. Worth noting: the accessory package is lean compared to the Quest Series — rotisserie kit is included but the griddle, cover, and liner are add-ons. Plan for those before you order.
-
Outdoor kitchen builders with a 38½-inch cutout — the TRL Pro 40 fills it with four independent high-output zones, nearly 900 square inches of total cooking surface, and an infrared rotisserie system that handles the largest cuts you'd want to put on a spit.
-
High-output cooks who want more than the Quest 42 delivers — the TRL Pro 40 runs 80,000 BTU main burner output (vs 72,000 on the Quest 42) with cast stainless burners at 20,000 BTU each, giving stronger per-zone output and better temperature recovery under a heavy load.
-
Large-group hosts who need to run a full menu simultaneously — 877 square inches means steaks, fish, vegetables, and warm-hold all run at the same time; no batching, no staggering courses, no food going cold while the next round finishes.
-
Serious rotisserie cooks — the 15,000 BTU infrared rear burner and 40 lb-capacity motor handle whole birds, large roasts, and heavy cuts through long sessions with consistent, even radiant heat throughout.
-
Builders who want ETL certification for their island install — the ETL mark means the grill has been independently tested to meet established safety standards, an important consideration for permitted outdoor kitchen projects.
-
Year-round and evening grillers — LED bezel status indicators across all four zones, halogen interior lighting, and battery-free Flame Thrower ignition mean the TRL Pro 40 performs as well at midnight in winter as it does on a summer afternoon.

Manuals & Documents›
Summerset TRL Pro 40-Inch — Frequently Asked Questions›
What are the cutout dimensions for the TRL Pro 40?›
The required cutout opening is 38½" wide × 20¾" deep × 9⅜" high. Download the Cut-Out Sheet above for contractor-ready reference. If your island is built from combustible materials, a Summerset Grill Liner is required and sold separately.
How many BTUs does the TRL Pro 40 produce?›
The four main cast stainless U-tube burners produce 80,000 BTU combined (20,000 BTU each). The infrared rear burner adds 15,000 BTU when in use, bringing the total output to 95,000 BTU when all five burner circuits are running simultaneously.
How does the TRL Pro 40 compare to the TRL Pro 32?›
The TRL Pro 40 adds a fourth 20,000 BTU main burner (80,000 BTU vs 60,000 BTU total), grows the total cooking surface from 692 in² to 876.61 in², and widens the cutout from 30½" to 38½". Both models share identical burner output per zone, the same infrared rear burner, the same lighting and ignition systems, and the same Gold Standard Lifetime Warranty. The 40 also carries ETL certification, which may be relevant for permitted installations. The same accessories (cover, griddle, liner, cart) are sold separately on both models.
How does the TRL Pro 40 compare to the Quest 42?›
Both are four-burner flagship built-ins but from different series. The TRL Pro 40 runs 80,000 BTU total main burner output vs 72,000 on the Quest 42, using 20,000 BTU cast stainless burners vs 18,000 BTU standard stainless on the Quest. The TRL Pro's rear infrared burner is also rated at 15,000 BTU vs 10,500 BTU on the Quest 42. The Quest 42 includes a more complete accessory package out of the box (griddle plate, smoker box, rib rack, grill cover in addition to the rotisserie kit), while the TRL Pro 40 includes only the rotisserie kit with everything else sold separately. The Quest 42 is made in the USA; the TRL Pro 40 is not.
What accessories come included in the box?›
The TRL Pro 40 includes the rotisserie kit (spit rod and 40 lb-capacity motor). All other accessories — grill cover, griddle plate, cart, and grill liner — are sold separately. If you need a griddle or cover, plan for those add-ons before your order ships.
Is the rotisserie kit included, and what is the motor's weight capacity?›
Yes — the rotisserie kit is included at no extra cost. The motor handles up to 40 lbs, which is sufficient for a whole turkey, a large roast chicken, a leg of lamb, or a bone-in prime rib. The motor plugs into a standard electrical outlet.
Can I add an infrared sear burner to the TRL Pro 40?›
Yes. Summerset makes a 20,000 BTU Drop-In Infrared Sear Burner for the TRL Pro Series, sold separately. It replaces any one of the four main burners to create a dedicated ultra-high-heat infrared searing zone — useful for building a deep crust on steaks or finishing proteins at extreme temperatures. Contact us for details before your island is finalized.
Is a grill liner required for built-in installation?›
If your island uses combustible materials — wood framing, plastic composites — yes, a Summerset Grill Liner is required to protect surrounding framing from heat transfer. Islands built from non-combustible materials with proper clearances may not require it — always confirm with the user manual and local codes before installation.
Can the TRL Pro 40 be used freestanding instead of built-in?›
Yes. A standard or deluxe freestanding cart is available from Summerset and sold separately, converting the built-in grill head into a movable freestanding setup.
What fuel types are available, and can I convert between them?›
The TRL Pro 40 is available in Natural Gas (TRLPRO40) and Liquid Propane (TRLPRO40L) — select your fuel type above before adding to cart. Fuel conversion may require a manufacturer-supplied conversion kit and professional installation; contact us before attempting any conversion.
What is Summerset's warranty on the TRL Pro 40?›
Summerset covers the TRL Pro 40 with their Gold Standard Lifetime Warranty for construction, cooking grates, burners, burner covers, valves, flame tamers, heat zone separators, ceramic briquette system, temperature gauges, and hood springs. Electrical components (LED lighting, wiring, switches, transformers, halogen lights) and all other parts carry a three-year warranty. Labor is excluded. Warranty must be registered online within 30 days of purchase; valid for the original purchaser at the original delivery site. Any out-of-box damage must be reported within 30 days of purchase and before installation.
Is the TRL Pro 40 made in the USA?›
No. The TRL Pro Series is not manufactured in the USA. If US manufacturing is important to your purchase, the Summerset Quest Series (available in 30", 36", and 42" built-in configurations) is made in the USA. Contact us for a comparison of both options for your island.
