AOG Grill Comparison Guide: L-Series vs T-Series

American Outdoor Grill (AOG) is the built-in grill brand from The Robert H. Peterson Co., a manufacturer with more than eight decades of outdoor cooking engineering experience and the parent company behind Fire Magic. AOG built-in grills are certified to ANSI Z21.58 and CSA 1.6 and are built with 304 stainless steel construction throughout the firebox, burners, and cooking grids.

The 2026 lineup is a redesigned generation of AOG built-ins, introduced as “All New. Boldly Refined.” The redesign covers two series — L-Series and T-Series — that share the same cooking architecture and cutout dimensions while differing in ignition system, lighting, and bundled accessories.

Brand position: AOG sits in the premium tier of residential built-in gas grills, alongside Lynx, Delta Heat, Coyote C-Series, and Blaze Premium LTE. The buyer is typically planning a permanent outdoor kitchen built-in grill installation rather than a freestanding cart grill.

Both series share the same cooking architecture: 304 stainless steel firebox, Diamond Sear™ 304 stainless cooking grids, heavy-duty 304 stainless tubular U-burners, redesigned vaporizer panels, spring-assisted hood, heavy-duty warming rack, large analog thermometer with die cast alloy bezel in Gun Metal finish, commercial-caliber handle, accessible control knobs with die cast alloy bezels, and a gas conversion kit included with every grill.

The differences fall into three categories.

The L-Series uses a Flame Thrower electronic ignition that lights every burner from a push of the control knob — no batteries. It draws power from the 120V / 15A GFCI outlet that also powers the lighting. The T-Series uses a Flame Thrower piezo ignition — turn-to-light, mechanical, no electricity, no batteries, no power source of any kind. If your install location has no electrical access, the T-Series is the only option.

The L-Series adds interior halogen oven lights for nighttime cooking, an external Multi-Color LED Light Bar with a remote control (and a built-in pocket holder for the remote in the drip tray), and an LED master power button. The T-Series has none of these — its control panel is fully analog.

The L-Series includes an Infrared Backburner and a complete rotisserie kit (spit rod, forks, motor) as standard equipment. The T-Series ships without a backburner and treats the rotisserie kit as an optional add-on (the kit includes spit rod, forks, motor, and mounting brackets when ordered separately).

In practical terms, the L-Series is the higher-equipment, lit, fully-bundled grill for cooks who want rotisserie out of the box and night-grilling visibility. The T-Series is the simpler, self-sufficient grill for installs without electrical access or for cooks who don’t need lights or a backburner.

The series-level feature comparison below shows what is standard, what is optional, and what is shared between the L-Series and T-Series. Per-size specifications — cooking area, BTU, cutouts, fuel availability — appear in the next section.

Both series share identical cutouts, cooking area, burner count, and main-burner BTU at each size. The L-Series adds a backburner BTU figure that the T-Series does not have. This means an L-Series and a T-Series of the same width are interchangeable in the same island opening.

Each grill ships preconfigured for the listed fuel and includes a gas conversion kit for field conversion to the alternate fuel by a qualified gas technician.

AOG specifies the following minimum clearances for both the L-Series and T-Series. These are the numbers that protect the surrounding structure from heat and protect the grill from poor ventilation. The values come from the AOG L & T Series Installation and Owner’s Manual.

Both series share the same gas connection requirements. The total BTU demand differs because the L-Series adds a backburner.

• Pipe size: ½″ minimum interior diameter. For runs longer than 20 feet, a larger diameter line may be required to deliver rated BTU input without pressure loss.
• NG inlet pressure: nominal 7″ water column, minimum 5″, maximum 10½″.
• LP inlet pressure: nominal 11″ water column, minimum 10″, maximum 13″.
• Manual shut-off valve is required in the supply line within 6 feet of the grill, easily accessible.
• C.S.A.-approved stainless steel flex connector with attached regulator is included and pre-installed at the valve manifold.
• No rubber hose inside the enclosure. Use pipe joint compound rated for all gases on NPT pipe fittings; do not use compound on flare fittings.

Every AOG built-in grill ships with a gas conversion kit. A unit shipped configured for natural gas can be converted to propane (and the reverse) by a qualified gas technician using the orifices and instructions in the Owner’s Manual.

Custom-built enclosures must be ventilated according to the gas type. AOG specifies the following minimums for both the L-Series and T-Series.

One side of the enclosure must be left fully open OR you must create one of the following vent setups:

• 1 minimum vent opening at top level with at least 20 sq in of free area, beginning 1″ or less below the countertop and ending no more than 5″ below the countertop, OR
• 2 vents (1 top + 1 floor) with at least 10 sq in of free area each, totalling 20 sq in. Floor vent begins 1″ or less above floor level and ends no more than 5″ above the floor.

One side fully open OR 4 vents:

• 2 top vents on adjacent walls (spaced at least 90° apart), 10 sq in free area each (20 sq in total), within 5″ of countertop.
• 2 floor vents on adjacent walls (spaced at least 90° apart), 5 sq in free area each (10 sq in total), within 5″ of floor.
• Total: 30 sq in free area minimum.
• For LP cylinders larger than 20 lb: at least 1 in² per pound of cylinder capacity for top vents and at least ½ in² per pound for bottom vents.

One side fully open OR 4 vents on adjacent walls (2 top + 2 floor at ≥90° spacing), each 45 sq in minimum free area, totalling 180 sq in.

• Every opening must allow at least a 3/16″ rod to enter.
• Maintain at least 6″ clearance from any items outside the enclosure.
• Maintain at least 2″ clearance from any items inside the enclosure.
• Vent openings in side walls cannot communicate directly with other enclosures of the appliance.
• Side-wall vents must not be located in front of the appliance above floor level.

The two series have opposite electrical requirements. The L-Series cannot operate without 120V; the T-Series requires no electrical connection of any kind.

The AOG L-Series requires a properly wired and inspected 120V AC, 15 AMP minimum, 60 Hz, GFCI grounded three-wire receptacle within reach of the unit. The receptacle must be a weather-proof in-use covered receptacle. The 120V supply powers the Flame Thrower electronic ignition, the interior halogen oven lights, the external Multi-Color LED Light Bar, and the LED master power button.

Plan the electrical rough-in before island construction so the receptacle sits inside the enclosure, accessible to the grill’s power harness, and protected from direct water exposure even with the in-use cover closed. Appliance rating: 12VDC / 60 Watts. Interior oven lights: 12V / 10-watt halogen bulbs.

The T-Series uses a Flame Thrower piezo (turn-to-light) ignition that runs without any electrical supply. No batteries, no cords, no GFCI receptacle, no power source of any kind. Each main burner lights from a turn of its control knob.

Every AOG built-in grill ships with the following standard equipment. Differences between L-Series and T-Series are noted by series.

• Diamond Sear™ 304 stainless steel cooking grids

Three questions decide the right configuration: ignition, size, and fuel.

If the island has — or can have — a 120V / 15A GFCI receptacle within reach (weather-proof, in-use covered), the AOG L-Series built-in grill is the broader-equipment option. The electronic ignition, interior halogen oven lights, multi-color LED light bar, infrared backburner, and standard rotisserie kit all rely on or pair with that 120V supply.

If the island has no electrical and adding an outlet is not viable, the AOG T-Series built-in grill is the answer. Its Flame Thrower piezo ignition needs no power, no batteries, and no maintenance. You can add a rotisserie kit separately later if you want one — the cooking grates, hood, vaporizer panels, and burners are identical to the L-Series.

• 24″ — 432 sq in / 32,000 BTU primary. Suits households of 2–4 people, occasional larger gatherings, and tight island footprints. The 24½″ × 19½″ × 8½″ cutout is the easiest to retrofit into an existing island.
• 30″ — 540 sq in / 45,000 BTU primary. Everyday 4–6 person built-in. Adds a third main burner and roughly 25% more cooking area than the 24″ without a major footprint jump (cutout 30½″ × 19½″ × 8½″). Most common reference size for residential outdoor kitchens and island-bundle plans.
• 36″ — 648 sq in / 50,000 BTU primary. For cooks who regularly host 6+ guests, want a full rotisserie loaded across the cooking surface, or use the warming rack as a working second tier. Cutout 36¾″ × 19½″ × 8½″.

The L-Series adds a backburner at every size — 10,000 BTU on the 24″, 12,000 BTU on the 30″ and 36″. If rotisserie cooking is a regular part of how you grill, that backburner is what powers it. The T-Series does not have a backburner; an optional rotisserie kit on the T-Series rotates over the main burners only.

If your home or yard is already plumbed for natural gas, a natural gas grill built in configuration is generally the lower-maintenance choice — no tank to swap, no LP cylinder ventilation requirements inside the enclosure. AOG offers natural gas in every size of both series.

If natural gas is not available, a propane built in grill configuration runs from a 20-lb cylinder kept inside the island enclosure (with the additional LP cylinder ventilation specified in the AOG Owner’s Manual) or from a remote LP supply. AOG’s propane availability:

• L-Series: 24″ (AOG24LP) and 30″ (AOG30LP)
• T-Series: 30″ (AOG30TP) and 36″ (AOG36TP)

Every AOG built in grill includes a gas conversion kit, so a unit shipped as natural gas can be field-converted to propane by a qualified gas technician.

• Permanent outdoor kitchen, full electrical, NG line, 6+ guests regularly: AOG36LN — 36″ L-Series Natural Gas. Maximum cooking area, infrared backburner, halogen lights, LED bar, rotisserie kit standard.
• Patio island, weekly cookout for a family of four, no overhead structure: AOG30LN or AOG30TN — 30″ Natural Gas. Pick L if you have 120V at the island; pick T if you don’t.
• Detached pool cabana with no electrical, propane only: AOG30TP or AOG24TN — Flame Thrower piezo, no power required.
• Compact island in a smaller backyard: AOG24LN, AOG24LP, or AOG24TN — 24″ with 2 main burners and 32,000 BTU. The 24″ is the only AOG built-in that fits cutouts under 28½″ wide.
