Comstock-Castle FSU330, 36 In. Step-Up Floor Gas Range

SKUFSU330 BrandComstock-Castle

The Comstock-Castle FSU330 Gas Range

The Comstock-Castle FSU330 is a 36-inch step-up gas range, built for high-volume kitchens needing an elevated cooktop layout that need a unit holding production temperature through full service without losing performance. The FSU330 is engineered for step-up open-burner cooking with overhead burner placement.

In a real kitchen, the 24,000 BTU output drives the 36-inch cooking surface at production temperature through service, with heavy cast iron components that hold heat between batches and recover fast when fresh product hits the unit.

This is the right call for high-volume high-volume kitchens needing an elevated cooktop layout at the production end of the volume range. If you only need a single-station unit for a prep line, the smaller siblings in the same series cut footprint.

24,000 BTU of Gas Output Driving the Cooking Surface

The unit fires 174,000 BTU across the 36-inch cooking surface, using cast iron burners or radiants that hold heat through wave after wave of cold product. Brass valves with standing pilot let the unit run on gas alone, no electrical hookup needed.

Welded Stainless Steel Body on Adjustable Legs

The FSU330 body is welded stainless steel with an angle iron and aluminized steel inner frame, set on adjustable stainless feet so the unit levels on any countertop or floor. Welded construction holds up under hot-cold cycling and daily pan abuse where bolted construction works loose after a season of service.

Brass Gas Valves with Standing Pilot, No Electric Hookup Required

Each control runs its own brass gas valve with a standing pilot, holding up against grease ingress where plated-steel valves pit and seize after a year of line service. No electrical hookup means the unit keeps running through a power outage as long as the gas line stays live.

About Comstock-Castle

Founded in 1838 in Quincy, Illinois, Comstock-Castle is America's oldest stove manufacturer still in operation. The company grew from a frontier hardware shop into a grey-iron foundry that helped make Quincy the nation's stove-production hub by the early 1900s. Seven generations later, Comstock-Castle still designs and union-builds commercial cooking equipment in the same Quincy facility, with ranges, griddles, charbroilers, fryers, and modular cook lines configurable from 24 to 72 inches to match your menu. Built to outlast the kitchens that put them on the line.

    The Comstock-Castle FSU330 Gas Range

    About Commercial Gas Ranges

    Commercial gas ranges are the backbone of most professional kitchens. They're built for volume, heat recovery, and daily use, things a residential stove can't keep up with. If you're running a restaurant, managing a kitchen, or outfitting a new foodservice space, this is where you start. The right range keeps up with back-to-back services, stands up to daily cleaning, and gives your cooks the control they need. Choose from open burner ranges or models with built-in griddles, depending on how your kitchen runs.

    Common Types and Configurations

    • Open burner ranges: The standard in most restaurant kitchens. Direct flame, easy to clean, and parts are easy to find.
    • Hot top ranges: Solid steel surface gives consistent, even heat. Best for soups, sauces, and holding food at temperature.
    • Range with griddle: Burners on one side, flat griddle on the other. Common in breakfast spots and busy diners.
    • 30-inch ranges: Compact size for smaller kitchens, but still built to commercial standards.
    • Heavy duty ranges: Thicker steel, higher BTU, reinforced grates. Made for kitchens that run all day.

    What to Look at Before You Buy

    • BTU output: Most commercial burners run 25,000 to 35,000 BTU. Higher output gives faster recovery but uses more gas.
    • Gas type: Most units are set up for natural gas. If you use propane, make sure LP conversion is available before you order.
    • Size: Measure your space carefully. Ranges come in 24, 30, 36, 48, and 60 inch widths. Make sure you have clearance for doors and traffic.
    • Installation: You need the right gas line size, a licensed installer, and a hood system that matches the BTU output.
    • Oven or base: Some ranges have a standard oven, others a convection oven or open storage base. Pick what fits your menu.

    Frequently Asked Questions

    What's the difference between a heavy-duty and a standard commercial range?

    It comes down to build quality and output. Heavy-duty ranges use thicker steel, higher BTU burners, and grates that stand up to constant use. Standard commercial units are fine for lower-volume kitchens. If your burners run nonstop across multiple services, choose heavy-duty. It will last longer and give you fewer problems.

    How many burners does my kitchen actually need?

    It depends on your menu and how busy your peak service is. A small cafe can get by with a 4-burner, 30-inch range. Most full-service restaurants need at least 6 burners, sometimes with a griddle. If you are always maxing out burners during service, you need more range, not more cooks.

    How do I know which size range is right for my kitchen?

    Start with your menu and your busiest service. A 4-burner, 30-inch range works for tight spaces and lighter menus. A 6-burner, 36-inch range covers most full-service restaurant needs. If you're running multiple stations or high-volume service, look at 48-inch or 60-inch units. Always measure your floor space and factor in clearance for doors, ventilation, and staff movement.
