Low-height single stock pot stove
The Atosa ATSP-18-1L puts big pots at a workable height
The ATSP-18-1L runs an 80,000 BTU three-ring cast iron burner on a stainless steel frame that stands just 17 9/10" tall. It’s built for the moment a tall pot is full of stock and someone has to stir it, skim it, or lift it off the fire.

Restaurants, commissaries, caterers, and production kitchens that boil stock, soup, pasta water, or crawfish in large pots and want the rim low enough to work over safely.
Why the ATSP-18-1L earns its space
One burner, serious outputA heavy-duty three-ring cast iron burner delivers 80,000 BTU per hour, enough to bring a large stock pot to a boil without tying up a range top.
Inner and outer rings on separate valvesEach 40,000 BTU ring has its own manual control. Run the inner ring to hold a gentle simmer overnight, then open both for a fast rolling boil. Two continuous pilots per burner keep ignition steady.
Low height for heavy loadsAt 17 9/10" tall, the ATSP-18-1L sits about 4 9/10" lower than the standard-height ATSP-18-1. That puts the top of a tall pot closer to chest level, which makes stirring, ladling, and draining easier on your crew.
Easy to keep cleanStainless steel sides and a stainless front valve cover wipe down fast, and a full-width removable drip pan catches boil-overs before they reach the floor.
Built for the long haulCast iron top grates carry heavy pots, stainless pilot tubing and pilot tips resist wear, and adjustable stainless legs level the unit on an uneven floor. It’s ETL listed and carries a 1-year parts and labor warranty.
Atosa ATSP-18-1L or ATSP-18-1
Atosa makes this stove in two heights. The ATSP-18-1L is the low version at 17 9/10", and the ATSP-18-1 is the standard version at 22 4/5". Burner, BTU rating, width, and depth are the same. If your team works with the largest stock pots in the kitchen, or you’re setting the stove on a low stand, the low-height model keeps the rim within easy reach. If you mostly run smaller pots and want them closer to counter height, the standard model may suit you better.

Buyer questions about the ATSP-18-1L
How is the ATSP-18-1L different from the Atosa ATSP-18-1?
The ATSP-18-1L is the low-height version, standing 17 9/10" tall versus 22 4/5" for the standard-height ATSP-18-1. Both are 18" wide with the same 80,000 BTU three-ring burner, so the choice comes down to how high you want the pot to sit and how heavy it’ll be when full.
How much heat does the ATSP-18-1L put out?
The ATSP-18-1L is rated at 80,000 BTU per hour in total, split as 40,000 BTU on the inner ring and 40,000 BTU on the outer ring. Each ring has its own manual valve, so you can run the inner ring alone for a simmer or both rings for a hard boil.
Does the ATSP-18-1L run on natural gas or propane?
Atosa lists the ATSP-18-1L in both natural gas and LP configurations. The natural gas version runs at 4" w.c. and the LP version at 10" w.c., and a regulator is included as standard, so confirm your gas type before you order.
What size space does the ATSP-18-1L need?
The ATSP-18-1L measures 18" wide, 20 9/10" deep, and 17 9/10" high, and it connects through a 3/4" NPT fitting at the rear. Plan for the gas line behind the unit and keep it under a hood, as you would any open gas burner.
Is the Atosa ATSP-18-1L ETL listed, and what’s the warranty?
Yes, the ATSP-18-1L is ETL listed for the U.S. and Canada. Atosa backs it with a 1-year parts and labor warranty.
