American Outdoor Grills L-Series Buying Guide: Finding Your Perfect Built-In Grill
American Outdoor Grills builds two built-in lines and only two: the L-Series and the T-Series. There is no third or entry line, whatever you may read elsewhere. The difference between them is narrower and more specific than most tier comparisons, and AOG states it plainly in its own installation manual.
This guide covers the L-Series — what it is, what it costs you in island work, and when the T-Series is the better buy. Every figure comes from AOG’s installation manual (document C2-768) and its 2026 Spec Guide.
The short answer
- The L-Series is the lit one. Halogen interior lighting, an exterior LED light bar, and a rear burner. The T-Series has none of those.
- The L-Series needs electricity. A 120V GFCI outlet in the island. The T-Series does not need one at all, which is a real saving if power is not already there.
- The L-Series comes in 24, 30 and 36 inches. There is no 42-inch L-Series.
- Construction is 304 stainless on both, with the same lifetime warranty on burners and housing.
L-Series vs T-Series: what AOG actually says
AOG’s installation manual puts the distinction in one sentence:
“T-Series grills are not equipped with lighting and do not require electrical connections.”
That is the whole of it, and it has a practical consequence most comparisons miss. The L-Series requires 120VAC, 15 amp minimum, 60 Hz, on a GFCI outlet, with the appliance itself rated 12VDC / 60 watts. If your island does not already have power, that is an electrician, a circuit and possibly a permit — and it has to be planned before the island is closed up, not after.
If the grill will live somewhere already well lit, or you are not running power to the island, the T-Series gives you the same steel and the same warranty without the electrical work.
The L-Series lineup
Three sizes, each in natural gas (N) or propane (P):
| Model | Main burners | Main BTU | Rear burner | Cooking area | Cutout (W × D × H) |
|---|---|---|---|---|---|
| AOG24L — natural gas / propane | 2 | 32,000 | 10,000 BTU | 432 sq in primary | 24½" × 19½" × 8½" |
| AOG30L — natural gas / propane | 3 | 45,000 | 12,000 BTU | 540 sq in primary | 30½" × 19½" × 8½" |
| AOG36L — natural gas / propane | 3 | 50,000 | 12,000 BTU | 648 sq in primary | 36¾" × 19½" × 8½" |
Note the 30 and the 36 both have three burners. The extra six inches on the 36 buys width and 5,000 more BTU across the same number of burners, not an extra zone. If independent heat zones are what you are after, that is worth knowing before you pay for the larger size.
AOG labels the cooking-area figure “primary cooking surface,” which indicates it is the main grate rather than a grate-plus-warming-rack total. AOG publishes no warming rack area, so we cannot give you a combined figure — and that matters when you compare against brands that quote the combined number. Our 30-inch and 36-inch comparisons explain why cooking-area figures are not directly comparable between brands.
AOG publishes total BTU rather than per-burner figures, so we do not quote a per-burner number for any L-Series model.
There is no 42-inch L-Series
The L-Series is 24, 30 and 36 inches. If you need a 42-inch built-in, you are looking at another brand — our 42-inch comparison covers what is actually available at that size.
Cutout dimensions
The openings are 24½", 30½" and 36¾" wide, all 19½" deep and 8½" from countertop to the bottom of the unit. The front panel overhangs the opening, at 28½", 34½" and 40¾" respectively, so allow for that at the face of the island.
Two things worth flagging:
- The 24-inch opening is wider than the grill’s nominal size. At 24½", AOG runs the opposite way to most brands, whose cutouts are narrower than nominal. Do not assume a 24-inch opening will take it.
- Older AOG model codes may differ. The figures above come from AOG’s current installation manual and its 2026 Spec Guide, which both describe the current L and T generation. Figures of 30⁵⁄₈" and 36⁷⁄₈" circulate for older AOG models. If you are replacing an AOG grill rather than buying into a new island, check the model code on the grill you have before sizing anything.
If you are working the other way round — you have an opening and need to know what fits — use the replacement grill finder. Our cutout dimensions reference has the published figures for every brand we carry.
Insulated liners, and what they do to the opening
AOG requires an insulating liner for installation in a combustible enclosure, and unlike many manufacturers it publishes the revised cutout rather than leaving you to guess:
| Grill | Liner part number | Liner cutout (side to side) | Increase |
|---|---|---|---|
| AOG24L | 24-IL-C | 28⁵⁄₈" | +4₁⁄₈" |
| AOG30L | 30-IL-C | 34⁵⁄₈" | +4₁⁄₈" |
| AOG36L | 36-IL-C | 40⁵⁄₈" | +3⁷⁄₈" |
The liner also adds about 2₁⁄₈" of depth and half an inch of height. Four inches of extra width is not a rounding error — it is the difference between an island that fits and one that does not. Decide about the liner before framing. More in do you need an insulating grill liner.
Warranty
AOG’s coverage is among the better structured in the category, and it is worth reading as a signal of what the manufacturer expects to last:
- Lifetime — stainless steel burners and stainless steel barbecue housings, “for as long as the original purchaser owns them.”
- 15 years — the Diamond Sear cooking grids.
- 10 years — valves and controls.
- 3 years — back burners and rotisserie components.
- 2 years — ignition and electronics.
The tiering tells you something useful: the parts AOG covers for the shortest period are the electrical ones, which are precisely the parts the L-Series adds over the T-Series. That is not a reason to avoid the L-Series, but it is worth weighing if lighting is not important to you. More context in why grill warranties matter.
Using an L-Series head on a cart
AOG publishes freestanding cart bases for its built-in heads — 24CRT-25, 30CRT-25 and 36CRT-25 — along with post bases, and a separate cart assembly document. So an L-Series head does not have to go into an island. The grill is the same either way; the cart is a separate part number. Our comparison of built-in vs freestanding grills covers that choice, including why it is not a quality decision.
Which AOG should you buy?
Choose the L-Series if you cook after dark, want a rear burner for a rotisserie, or are already running power to the island for a refrigerator or lighting. The lighting is the feature people notice most in daily use.
Choose the T-Series if there is no power at the island and you would rather not add it, or if you want the same construction and warranty for less. AOG’s own positioning is that the T-Series is the same grill without lighting and without an electrical requirement — see the T-Series 30-inch for the direct comparison.
On size, the 30 and the 36 share a burner count, so the 30 is the efficient buy unless you specifically want the wider grate. The 24 is a genuinely small grill at two burners and suits a compact patio or a secondary station.

Common questions
What is the difference between AOG L-Series and T-Series?
Lighting and electricity. AOG’s manual states that “T-Series grills are not equipped with lighting and do not require electrical connections.” The L-Series adds halogen interior lighting, an exterior LED light bar and a rear burner, and requires a 120V GFCI outlet. Construction, cutouts and warranty are otherwise the same.
Does the AOG L-Series need electricity?
Yes — 120VAC, 15 amp minimum, 60 Hz, on a GFCI outlet, with the appliance rated 12VDC and 60 watts. Plan the circuit before the island is closed up. The T-Series needs no electrical connection at all.
What cutout does an AOG L-Series grill need?
24½" for the 24-inch, 30½" for the 30-inch and 36¾" for the 36-inch, all 19½" deep and 8½" from countertop to the bottom of the unit. Note that the 24-inch opening is wider than the grill’s nominal size. If the island is combustible and needs a liner, add roughly four inches of width.
Is there a 42-inch AOG L-Series grill?
No. AOG builds the L-Series in 24, 30 and 36 inches only.
How many burners does the AOG 36-inch have?
Three, the same as the 30-inch. The 36-inch has more width and a higher total output (50,000 BTU against 45,000), but not an additional burner or heat zone.
Does AOG include a rotisserie?
The L-Series has the rear burner a rotisserie needs, and AOG publishes a separate rotisserie instruction sheet. AOG’s own catalogue is not consistent about whether the kit ships with the grill, so we will not state it either way — ask us and we will confirm for the specific model before you order.

Where AOG publishes totals rather than per-burner figures, or publishes nothing at all, this page says so rather than filling the gap. Cutout figures describe the current L and T generation; older model codes should be checked individually.
