A 48" Lava Rock Countertop Gas Grill
This countertop gas grill is a 48" lava rock charbroiler with four 35,000 BTU burners and 140,000 BTU in total. Lava briquettes come standard, and the cast iron grates are reversible.
Lava Rock or Radiant: Is the ATCB-48 Right for Your Line?
The ATCB-48 is a 48" lava rock charbroiler: four 35,000 BTU burners under a bed of lava briquettes, 140,000 BTU in total, with a 47-9/10" x 20-1/5" cooking area (about 968 sq in) on reversible cast iron grates. It weighs 247.8 lb (313.7 lb shipped).
Lava rock or radiants? Both Atosa lines share the same burners, BTU and grates. The difference is what sits between the flame and the food. Lava rock holds heat and drippings, which many cooks choose for a smokier flavor, but the rock has to be spread evenly (Atosa calls for pieces about 3 to 5 cm across) and replaced as it wears. The radiant ATRC-48-NG has no rock to manage and weighs 47.2 lb less.
The ATCB is natural gas only in our lineup. For a propane charbroiler from the factory, see the radiant ATRC-48-LP. Short on space? The ATCB-36 is 36" wide. Pair it with a griddle at the same 48" width: the ATTG-48-NG thermostatic griddle matches its 15-1/5" height, and the CookRite ATG-4824-S has a 1" polished steel plate 24" deep.

Before You Order
- This listing is the natural gas model, the only ATCB version we carry. For a factory propane charbroiler, see the radiant ATRC-48-LP.
- Gas: 3/4" NPT rear connection with a regulator. Atosa sets it at 4" W.C. for natural gas.
- Check your counter: the ATCB-48 is 48" wide, 27-3/5" deep and 15-1/5" tall, per the Atosa drawing. It weighs 247.8 lb with the lava rock setup, so use a counter or stand rated for that weight.
- Atosa's manual says to set it on a non-combustible counter, leave at least 6" on both sides and the back and 4" below, and install it under an exhaust hood as local code requires.
- Atosa's manual says an authorized, licensed technician must install it, and that it is not for outdoor use.
- Atosa's manual lists spare A18 orifices in the accessories for switching gas type, and says an authorized, licensed technician must make the change, including the regulator.
Setup and Care
- Spread the lava rock evenly on the bottom frame. Atosa calls for rocks about 3 to 5 cm across.
- Preheat the burners for 15 to 20 minutes before broiling, then set the flame for what you are cooking.
- Expect some smoke the first time you heat it. Atosa says it goes away after running at full heat for about an hour.
- The grates are reversible: use the side with the grease trough for fatty foods, or the flat side. You can also tilt them.
- Do not hose down or pressure wash the charbroiler (the catch tray is the exception), and do not use abrasive or corrosive cleaners.
- Atosa says to have it checked once a year by an authorized, licensed technician.
