American Outdoor Grills L-Series Buying Guide: Finding Your Perfect Built-In Grill
American Outdoor Grills L-Series Buying Guide: Finding Your Perfect Built-In Grill
If you're planning an outdoor kitchen, the American Outdoor Grills (AOG) L-Series is built for cooks who want serious grilling power in a grill head made entirely from 304 stainless steel, inside and out. Every model in the line shares the same core engineering: U-shaped stainless steel main burners, Diamond Sear cooking grids for even heat retention and searing, an infrared rear burner paired with an included rotisserie kit, and interior halogen lighting for cooking after dark. The real decision isn't quality — it's matching the grill's size to your outdoor kitchen and choosing the fuel type that fits your gas setup.
Choosing a Size
The L-Series comes in three widths built for different kitchens. The 24" Built-In Grill is the compact option, with two main burners producing 32,000 BTUs across 432 square inches of primary cooking area (548 square inches total with the secondary warming space), plus a 10,000 BTU infrared rear burner and included rotisserie kit — so even the smallest footprint doesn't skip rotisserie cooking. Step up to the 30" Built-In Grill for three main burners, 45,000 BTUs, and 540 square inches of primary grilling space (691 total), backed by a 12,000 BTU rear burner and rotisserie kit — a comfortable middle ground for most households. For the most cooking capacity, the 36" Built-In Grill tops out the line with 50,000 BTUs across 648 square inches primary (829 total), also paired with a 12,000 BTU rear burner and rotisserie kit — enough grilling and roasting capacity for full backyard entertaining.
Propane or Natural Gas?
Every size in the L-Series is available in both propane and natural gas, and the choice comes down to your existing gas setup rather than performance — cooking specs (BTUs, grate size, burner count) are identical between fuel types at each size, and pricing is the same too. Propane models run on refillable tanks, the simpler install if you don't already have a gas line to your patio. Natural gas models connect directly into your home's existing gas line, so you never swap a tank, but they require professional installation of a gas hookup.

Rounding Out the Kitchen
Once you've chosen your grill, two accessories complete the L-Series installation. The Insulating Liner (model 36-IL-C, $1,268.00) is sized for 36" L-Series and T-Series grill heads and is recommended — though not automatically required — when building into combustible cabinetry or an island surround, shielding surrounding materials from heat. For added cooking capacity, the Double Side Burner is available in propane or natural gas, each $1,640.00, pairing two 12,500 BTU solid brass burners (25,000 BTUs combined) with a stainless steel rod grid, protective cover, and piezo ignition to match the L-Series look.
