Atosa CookRite ATG-2424-S 24-Inch Thermostatic Polished Steel Griddle, Natural Gas, 60,000 BTU

Who the ATG-2424-S Is For

The ATG-2424-S is the entry point to Atosa's heavy ATG line: a full 24" x 24" plate, two thermostatic zones and 30,000 BTU under each 12" section, at the lowest price in the series. It suits a café that runs breakfast sandwiches all morning, a bar kitchen where one cook handles the griddle between fryer baskets, or a restaurant adding a dedicated egg station beside an existing range.

The two zones are the practical draw. Set the left side at 325°F for eggs and the right at 375°F for bacon or hash browns, and each burner cycles on its own snap-action thermostat to hold that number while the cook steps away.

Common fits:

• Cafés and coffee bars with a breakfast menu
• Bar and pub kitchens with one cook on several stations
• A second, dedicated egg or pancake griddle
• Concession counters on a natural gas line

Polished Steel or Chrome

On a 24" plate the steel-versus-chrome question mostly comes down to budget. The ATG-2424-S has the same 1" plate thickness, burners, thermostats and footprint as the chrome ATG-2424-C, at the lower price.

Steel is seasoned and builds a release layer with use. At 576 square inches, one seasoning coat takes roughly 4 ounces of oil. Chrome skips seasoning, and Atosa says it reduces radiant heat, minimizes sticking and flavor transfer, and can help lower energy use, but it cannot take abrasive cleaners or griddle stones. Pick steel if your crew scrapes hard and seasons by habit; pick chrome if heat at the station or flavor carryover is the bigger problem.

Choosing the Width

At 24" wide this is the compact ATG. Plan about 36" of counter with Atosa's 6" side clearance to combustible construction. If you expect the griddle to become your main station, look at the ATG-3624-S now rather than outgrowing the 24" later.

ATG-2424 vs. ATTG-24 and ATMG-24

At 24" Atosa offers three gas griddles. The ATG-2424 puts 60,000 BTU behind a full 24" deep, 1" thick plate. The ATTG-24-NG is also thermostatic but runs 50,000 BTU on a plate about 20" deep, and the ATMG-24-NG has full 30,000 BTU burners on manual valves with a 3/4" plate. On a two-zone griddle, the deeper plate is the biggest practical gain: more room to hold food at the back without crowding the cooking area. If you do not need chrome, the real choice is ATG versus ATTG: both are thermostatic with 1" steel.

Running 2 Zones

Each 12" section has its own thermostat from 200°F to 450°F, and the burner cycles to hold the setting. With only two zones, most kitchens split the plate by task: one side for eggs at about 325°F, the other for bacon or hash browns at about 375°F. One cook can run both sides without moving. Atosa suggests lower temperatures on the outer sections and higher ones toward the center when zone cooking. Allow 20 to 25 minutes to preheat, and avoid crowding a zone right after loading.

To check calibration, Atosa's method is to set 350°F, let the zone cycle on and off at least twice, then read the center of each zone with a surface thermometer. Expect 350°F ±15°F. Atosa does not recommend infrared thermometers for this check.

Natural Gas Setup

The ATG-2424-S ships configured for natural gas with a 3/4" NPT rear connection and a convertible regulator preset to 4" W.C. At full fire it draws 60,000 BTU per hour, about 60 cubic feet of natural gas per hour. Size the gas line for that load plus everything else on the same supply.

For a griddle on its own branch, using the code capacity table in our natural gas line sizing guide: 3/4" pipe carries 60 CFH past 100 feet, so a dedicated 3/4" branch covers this model on almost any layout. A shared line has to be sized for the combined load, and your gas fitter makes the final call.

The Restaurant Warehouse sells the ATG line in natural gas only. Atosa's manual allows conversion to propane by a qualified, licensed technician, who changes the burner and pilot orifices, inverts the regulator plug to 10" W.C. and labels the rating plate. If you know you need propane, the ATTG-24-LP and ATMG-24-LP are built for it. See what a gas conversion involves.

ATG-2424-S Specifications

Installing the ATG-2424-S

• Hood: Atosa requires installation under a commercial ventilation hood, with at least 18" between the flue outlet and the hood filters.
• Clearances: Atosa's manual lists 6" at the back and sides from combustible construction and 4" of open space underneath. Do not box in the bottom.
• Counter or stand: 217 lb on a surface at least 32" deep. Level the plate front to back and side to side, and do not extend the legs more than 1-3/4".
• Casters: on a stand with casters, use a listed flexible connector, a quick disconnect and a restraint.
• Gas: manual shutoff upstream, LP-resistant pipe compound, soap-and-water leak test, never a flame.
• First light: preheat 20 to 25 minutes before cooking.

Installation must be done by a qualified, licensed technician to local code or the National Fuel Gas Code. Shipping is free on orders over $500 with lift gate delivery.

First Use, Seasoning and Daily Care

The plate ships with a rust inhibitor. Atosa's steps for polished steel: heat to 200–300°F for about 30 minutes, clean with a non-corrosive commercial cleaner, rinse and dry. Then season at 300–350°F with about 1 ounce of cooking oil per square foot, spread with a lint-free cloth, bake it in, wipe off the excess and repeat until the finish turns smooth and dark. At 576 square inches, one coat takes roughly 4 ounces of oil.

• During service: scrape with a flexible spatula or griddle scraper and keep the grease moving to the drawer.
• End of day: turn the thermostats off, let the plate cool to warm, empty and wash the 4 qt grease drawer.
• Weekly: clean the splashes and front panel, check burner ports, and keep grease out of the flue.
• Re-season after any deep cleaning, and oil the plate lightly before a long shutdown.

Never put water on a hot plate. See the main guide's cleaning section for more.
