The Comstock-Castle F318-1RB Gas Range
The Comstock-Castle F318-1RB is a 24-inch heavy-duty restaurant gas range built for tight-footprint kitchens, food trucks, and prep stations that need 2 open burners plus a 12-inch radiant charbroiler section working through full service without losing heat. It pairs that cooktop with a 19.5-inch standard oven sized for half sheet pans and full-size hotel pans.
In a real kitchen, the 103,000 BTU output means the two 24,000 BTU front burners hold steady-state sauces while the two 30,000 BTU rear burners run hot for searing, so a 24-inch line can finish proteins on the back row without dropping heat on the front. The 19.5-inch oven takes half sheet pans and most full-size hotel pans, with a 24,000 BTU cast iron oven burner.
This is the right call for tight-footprint kitchens, food trucks, and prep stations where the 2 burners + 12" charbroiler layout matches your menu mix. If you're feeding a full restaurant line, the 30-inch or 36-inch siblings in Comstock-Castle's 24-inch range family give you more burners on the same chassis. The F318-1RB is sized for prep stations, food trucks, and tight kitchen footprints where width matters more than concurrency.
Star-Pattern Open Burners with Asymmetric Front/Rear BTU Layout
The cooktop uses 24,000 BTU front burners paired with 30,000 BTU rear burners, letting a line cook hold a steady simmer on the front row for sauces while the rear row runs hotter for searing or boiling. Each burner is a star-pattern open burner with a 7-inch flame spread, so a 12-inch pan heats edge to edge instead of just at the center. The 12-by-12-inch cast iron grates lift off for cleaning and are shaped with spillover bowls that reflect heat back at the pan and catch boil-over before it reaches the burner heads.
One 19.5-Inch Standard Oven with H-Pattern Cast Iron Burner
Each oven cavity is 19.5 inches wide by 22 inches deep by 14 inches tall, sized for half sheet pans and most full-size hotel pans. The oven burner is a 30,000 BTU H-pattern cast iron unit paired with a V-shaped baffle that pushes heat around the cavity for even browning instead of straight up the back wall. Linings are porcelain on the surfaces you scrub and aluminized steel on the structure. Each oven ships with one nickel-plated rack on three positions spaced two-and-three-quarter inches apart, with 4-1/2 inches maximum clearance at the highest rack position. A 500°F thermostat with 100% safety shut-off holds the cavity steady, and the standing pilot lights the burner without an electrical hookup, so the F318-1RB keeps running through a power outage as long as the gas line stays live.
Welded Stainless Steel Chassis on 6-Inch Heavy-Duty Pipe Legs
The cabinet is welded, not bolted: angle iron and aluminized steel inner frame, stainless steel exterior, double-wall construction with heavy fiberglass insulation between the walls. Welded chassis stay square through years of hot-cold cycling and the daily abuse of pots banging against the front rail; bolted construction works loose after a couple of seasons and shows up as a rattle in the door and a misaligned cooktop. The double-wall insulation keeps the outside surfaces cool enough that a line cook can lean in to plate without flinching, and it cuts the radiated heat your hood has to deal with. The F318-1RB stands on six-inch heavy-duty stainless steel pipe legs with adjustable feet so you can level it on an uneven kitchen floor.
500°F Thermostat, 100% Safety Shut-Off, and Brass Top Burner Valves
If the pilot ever drops, the 100% safety shut-off cuts gas flow at the oven within seconds with no manual reset wand-walk required. Each top burner runs its own brass valve, which holds up against grease ingress in a way plated-steel valves do not (plated valves pit and seize after a year of line service). Pressure regulators are factory-set to 4 inches of water column for natural gas or 10 inches for propane, and the manifold is 3/4-inch NPT. Controls are tested before the unit ships and pressure regulators come factory-set.
Sister Configurations in the Same Chassis for Different Menu Mixes
This F318-1RB ships as the configuration described above. If a menu pulls heavier on a different cooking method, the same 24-inch chassis is available as separate SKUs that swap open-burner pairs for 12-inch, 24-inch, 30-inch, or 36-inch griddles, radiant charbroilers, hot tops, or cheesemelters in 12-inch increments. The F318-1RB is the right call when this specific cooktop layout matches how your line actually cooks.
Factory Accessories for Bake, Hood, and Service Programs
Optional add-ons available from the factory include casters for rolling cleanout, extra oven racks, pizza decks for the oven, FD oven thermostats, oven spark pilots, chrome griddle plates, 1-inch-thick griddle plates, griddle thermostats, safety-pilot griddles, lift-off griddles, automatic grill scrapers, hose and quick disconnects, control protection bars, low backs, and a storage base that replaces the oven cavity for kitchens that need cabinet storage more than oven capacity. These are factory accessory SKUs added to the order at purchase; they do not ship with the base F318-1RB unit.
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.
