How to Choose the Right Commercial Gas Range

A commercial gas range (or commercial gas stove, same equipment) is the appliance that decides how fast your line moves. The right unit recovers in seconds when a saute pan of cold protein hits a 30,000 BTU burner. The wrong one stalls at the worst possible moment, holds up tickets, and burns through wear parts every six months. This guide walks through the buying decisions that matter: configuration, BTU output, ignition style, certifications, install requirements, and total cost of ownership. For background on the equipment category and how it compares against other cooking platforms, see the restaurant ranges master guide.

Step 1: Match the Range to Your Menu, Not the Other Way Around

The biggest buying mistake is sizing by price tier instead of menu. Before looking at any model, write down what you will cook during your busiest hour on your busiest day. That dictates burner count, BTU mix, and oven configuration.

• Saute-heavy menu (Italian, French, Asian). Prioritize high-BTU open burners. 6 to 10 burners at 28,000 to 32,000 BTU each. Atosa AGR-6B (36 inches, 6 burners, 1 oven) is the workhorse here.
• Breakfast or burger menu. Combination range with integrated griddle. Atosa AGR-4B36GR (4 burners + 36-inch griddle) or AGR-6B24GR-NG (6 burners + 24-inch griddle).
• Pizza, bakery, or roast-heavy menu. Prioritize oven capacity. 48-inch or 60-inch range with two ovens. Atosa AGR-8B (8 burners, 2 ovens) or AGR-10B (10 burners, 2 ovens).
• Food truck, prep station, or low-volume cafe. 24-inch range with 4 burners and 1 oven. Atosa AGR-4B. For catering, pop-ups, or temporary stations, countertop gas hot plates and portable butane ranges deliver real heat without a permanent install.
• Stockpot or soup focus. Consider a dedicated stock pot range alongside your main range. Stock pot ranges sit low to the floor (safer for moving heavy pots) with oversized burners engineered to bring 40-gallon pots to a rolling boil.
• Wok station. A wok range uses a bowl-shaped opening that cradles the round bottom of a wok and a powerful jet-style burner aimed directly at the pan base. Wok hei (the smoky char of authentic stir-fry) comes from sustained 100,000+ BTU jet flames a standard range cannot produce.

If your menu is wide, buy for the widest dish at the busiest hour. Eight burners covers most independent restaurants. Ten or twelve burners is right for high-volume operations, banquet kitchens, and any kitchen running multiple stations off the same range. Commercial gas ranges span 12 inches (single-burner countertop) to 72+ inches (12-burner industrial), so kitchens of every size have a fit.

Step 2: Understand BTU and What It Actually Costs You

BTU (British Thermal Unit) measures heat output per hour. Commercial open burners run 25,000 to 32,000 BTU, with high-output specialty burners pushing 35,000. Residential burners top out around 18,000 BTU. The commercial advantage is not just maximum heat, it is recovery: a commercial burner returns to full output in seconds after cold product hits the pan. A residential burner stalls.

But a higher BTU rating does not automatically mean a better range. BTU measures heat output, not how efficiently that heat reaches the pan. A well-engineered burner with 30,000 BTU and tight flame geometry can outperform a poorly designed 35,000 BTU burner with sloppy flame distribution. Read the spec sheet and look at independent reviews before assuming bigger is better.

For most cooklines, you want a mix:

• High-output burners (28,000 to 32,000 BTU) for searing, blackening, stir-frying, and rapid boiling.
• Lower-output burners (12,000 to 18,000 BTU) for simmering reduction sauces, melting butter, and holding stocks at temperature.
• Dual-ring burners on some models combine both, letting one burner deliver high heat or low simmer from the same head.

The Atosa AGR line uses 28,000 to 32,000 BTU open burners across the range, with a 30,000 BTU oven burner in the base. Total output by size: 4-burner ~155,000 BTU, 6-burner ~219,000 BTU, 8-burner ~304,000 BTU, 10-burner ~374,000 BTU.

Step 3: Open Burners, Sealed Burners, Hot Tops

Open burners are the commercial standard. Visible flame directly under the pan, highest BTU output, instant visual feedback for the chef. The Atosa AGR line uses open burners. Drawback: spills can fall into the burner assembly, so daily cleaning matters.

Sealed burners have the burner head fused to the cooktop. Spills can not get into internal components, easier to clean, but typically 21,000 to 30,000 BTU, slightly less than open burners. Found on a few commercial models and most residential gas ranges.

Hot top ranges replace open burners with a solid, heavy steel plate covering the burners. The plate creates one large cooking surface with graduated heat: hottest directly over the burner, cooling toward the edges. Cooks slide pots around to find the right temperature instead of lifting and resetting. Best for soup and sauce kitchens running 8+ holding pots simultaneously. The Atosa AGR line does not include hot top configurations; if you need this, special order.

Stock pot ranges are low-profile units (often 12 to 17 inches tall) with one or two oversized burners (50,000 to 100,000+ BTU) at near-floor level. Designed to handle 40-gallon stockpots safely. Cast iron grates engineered to support hundreds of pounds. Sit alongside the main range when soup and stock production is a daily operation.

Step 4: Oven Below the Burners

Almost every commercial gas range under 60 inches includes one full-size oven in the base. Larger units (48-inch, 60-inch) include two side-by-side ovens.

Standard oven. Convection-free, gas burner at the bottom of the cavity. Holds a full sheet pan (18 by 26 inches). Workhorse for baking, roasting, braising, and holding. The Atosa standard oven runs 30,000 BTU and is thermostatically controlled from 175 degrees Fahrenheit to 550 degrees Fahrenheit. High-density fiberglass insulation in the floor, sides, and door retains heat and reduces radiated heat into the cookline.

Convection oven. Adds a fan that circulates hot air for even cooking. Cooks up to 25 percent faster than a standard oven; drop your recipe by 25 degrees Fahrenheit when converting and check doneness about two-thirds of the way through original time. Better for bread, pastry, sheet-pan vegetables, and high-volume roasting. Atosa does not currently offer convection in the AGR line; pair the range with a separate countertop or freestanding convection oven for baking volume.

Cabinet base (no oven). Some models swap the oven for storage cabinet. Useful when your kitchen already runs a separate combi oven or rack oven and you only need cooktop burners.

Space-saver oven. Compact oven with full functionality in a smaller footprint. Found on countertop and 24-inch ranges, designed for food trucks and tight cooklines.

Step 5: Ignition System (Standing Pilot vs Electronic)

Two common ignition systems on commercial gas ranges, each with tradeoffs.

Standing pilot (millivolt system). A small flame burns continuously and lights each burner when the knob opens the gas valve. Pros: extremely reliable, no electrical dependency, works during power outages, parts are universal and cheap to replace, simpler troubleshooting. Cons: constantly burns a small amount of gas. The Atosa AGR line uses standing pilot ignition.

Electronic ignition (pilotless). An electric spark lights the burner only when the knob is turned. Pros: more gas-efficient, no constant flame to relight after a draft, modern safety features integrate easily. Cons: requires electrical connection, adds failure points (igniter modules, control boards), repair parts are more expensive, will not work during power outages.

Most independent operators prefer standing pilot for simplicity and reliability. High-volume kitchens running 14+ hours per day sometimes choose electronic ignition for the gas savings.

Step 6: Required Safety Features

• Flame Failure Device (FFD). Automatically shuts off the gas supply if a burner or oven pilot is extinguished by a draft, boilover, or fuel interruption. Code-required on commercial gas ovens. Atosa builds FFDs into the oven pilot.
• Anti-tilt bracket. Required code in most jurisdictions. Secures the back of the range to the wall or floor to prevent tipping forward when a heavy stockpot is pulled off the rear burner. Ships with most Atosa AGR units; verify the install includes it.
• Cool-touch knobs and a heat-resistant front panel. Prevents burns on staff during service.
• NSF certification. National Sanitation Foundation listing. Required in most jurisdictions for any cooking equipment in a licensed foodservice operation. Means the unit is designed to be easy to clean and meets sanitation standards.
• ETL Listed. Electrical and gas safety certification. Required for code compliance.
• cETLus / CSA certification. Confirms compliance with US and Canadian safety standards.

All Atosa AGR commercial gas ranges carry NSF and ETL certifications. Walk away from any unit that does not.

Step 7: Build Quality Checklist

• 304 or 430 grade stainless steel on front, sides, and top. 304 is more corrosion-resistant in salt and grease environments. Galvanized or painted steel on the sides is a cost-cutting red flag.
• Heavy-duty cast iron grates. Cast iron retains heat exceptionally well and distributes it evenly. Atosa uses 12 by 12 inch reversible cast iron top sections that flip for even wear and lift out for cleaning. Cheap stamped steel grates warp under heavy stockpots.
• Lift-off cast iron burner heads. Burner heads should remove without tools so you can clear clogged ports and inspect the orifice. A properly seated burner produces a steady, concentrated ring of blue flame; yellow tipping or dead spots in the flame ring indicate clogged ports or misalignment.
• Full-width stainless drip trays. Positioned under the burners to capture grease and food debris before it reaches the manifold or chassis floor. Removable and dishwasher-safe.
• Welded frame construction instead of bolted. Welded frames hold up under daily wear; bolted frames develop play and rack out of square within a few years.
• Heavy-gauge brass manifold with separate valves per burner. Brass resists corrosion from grease vapor. Plated zinc manifolds corrode within 2 to 3 years.
• 3/4-inch thick polished steel griddle plate on combination ranges. The thickness acts as a thermal battery, holding stable temperature when cold product hits the surface.
• 6-inch adjustable stainless legs or heavy-duty casters. Adjustable legs level the unit on uneven floors. Casters are essential for line configurations where the range must be rolled out for deep cleaning behind and underneath; verify caster weight rating against the unit's loaded weight.
• 304 or 430 grade stainless on kick plate, backguard, and over shelf not just the front. Hidden surfaces are where cost-cut builds substitute galvanized steel that corrodes in two to three years.
• Removable drip pans, lift-off cast iron grates, and removable burner heads for daily cleaning access.
• Metal knobs and robust gas valves. Plastic knobs and cheap valves are the first parts to fail on bargain units.

Step 8: Installation Requirements

Commercial gas range installation is not a DIY project. Every install requires:

• Type I grease hood with fire suppression, sized to cover the unit plus 6 inches on each side per most local code. Hood airflow typically runs 150 to 300 CFM per linear foot of hood, calculated by your hood vendor to match the BTU load underneath.
• Gas supply line sized for total BTU load. Undersized gas lines starve the appliance, void warranty, and are dangerous. A licensed plumber should evaluate the line size before installation. Gas lines for 8-10 burner ranges are typically 3/4 inch to 1 inch.
• Gas pressure. Manifold pressure is 4 inches water column (W.C.) for natural gas, 10 inches W.C. for liquid propane on Atosa units. Supply pressure upstream of the regulator runs 6 to 9 inches W.C. for NG, 11 to 14 inches W.C. for LP.
• Gas regulator matched to fuel type. The regulator ships with the unit. Installing an LP regulator on NG supply (or vice versa) produces yellow lazy flames, sooting, and incomplete combustion.
• Anti-tilt bracket securing the back of the range to the wall or floor.
• Clearance from combustibles: typically 6 inches minimum on sides and back per the unit spec sheet.
• Gas shut-off valve accessible upstream of the unit.
• Floor or stand rated for unit weight (Atosa AGR-6B is roughly 410 lbs, AGR-10B is over 650 lbs).
• Liftgate delivery if you do not have a loading dock or forklift. A liftgate is a hydraulic platform on the delivery truck that lowers heavy equipment to ground level.

Always verify against your local AHJ (Authority Having Jurisdiction) before purchase. Building and fire codes vary by city, county, and state.

Step 9: Price Ranges and What Drives Cost

Commercial gas range prices vary widely by configuration and brand. Atosa pricing as a reference point (subject to change):

• 24-inch / 4-burner / 1 oven (AGR-4B): $1,700 to $2,200
• 36-inch / 6-burner / 1 oven (AGR-6B): $1,800 to $2,400
• 48-inch / 8-burner / 2 ovens (AGR-8B): $3,200 to $3,500
• 60-inch / 10-burner / 2 ovens (AGR-10B): $3,500 to $4,000
• Combination ranges (burners + griddle): add $500 to $1,200 depending on configuration.

What pushes the price up:

• Number of burners and oven count
• Built-in griddle, charbroiler, or raised broiler add-ons
• Convection oven (vs standard)
• Electronic ignition systems and digital controls
• Established brand premium
• Specialty configurations (wok burners, infrared broilers)

For most independent restaurants, an Atosa AGR-6B at 36 inches with 6 burners and 1 oven covers 80 percent of cooklines for under $2,400. Equipment financing is available if you want to spread the cost over monthly payments.

Step 10: New vs Used

New commercial gas ranges come with a full manufacturer warranty (typically 1 to 2 years parts and labor), the spec sheet matches the build, and the unit ships clean. Used commercial gas ranges sell at 40 to 60 percent of new pricing but come with real risk:

• No warranty, sold as-is
• Wear parts (gaskets, thermocouples, valves) may need immediate replacement
• Burner ports may be partially clogged from years of grease
• Oven thermostat may be out of calibration
• Hidden corrosion under the chassis or behind the manifold

If buying used, inspect for: dents and rust on the chassis; smooth knob operation on every burner; steady blue flame on every burner (yellow flames indicate orifice or air mixture issues); tight oven door seal (sit a piece of paper in the door, close it, try to pull the paper out; it should grip); oven temperature accuracy with an independent thermometer (within 25 degrees Fahrenheit of setpoint); intact gas connections without grease buildup; dimensions and gas type matching your install requirements.

The math: a new Atosa AGR-6B at $2,200 versus a used 36-inch range at $1,100. If the used unit needs $400 in parts plus $200 in tech labor, you saved $500 against a unit with no warranty and unknown remaining life. For high-volume operations, new is almost always the better long-term investment.

Step 11: Total Cost of Ownership

Purchase price is only one component of what the range actually costs you over its life. Factor in:

• Gas consumption. Standing pilot burns roughly $5 to $15 per month per pilot in continuous gas. Electronic ignition cuts this to zero but adds replacement cost when igniter modules fail.
• Maintenance. Plan for one parts replacement cycle (gaskets, thermocouples, valves) over a 10-15 year life. Budget $300 to $500 per year for parts and tech labor on a 6-burner range.
• Downtime. Ten minutes of cleaning at end of shift prevents hours of service interruption. Clogged burner ports alone can reduce effective BTU output by up to 30 percent, slowing tickets and burning more gas to deliver the same heat.
• ENERGY STAR. ENERGY STAR-rated commercial cooking equipment (where the certification applies, usually to the oven) typically reduces utility cost 15 to 30 percent vs standard models over equipment life.
• Service contract. Annual professional servicing is recommended; high-volume kitchens may consider bi-annual. A tech with a manometer can catch small gas leaks, calibrate the thermostat to plus or minus 5 degrees Fahrenheit, and replace worn parts before they cause downtime.

A well-maintained Atosa AGR commercial gas range will run 10 to 15 years on a working cookline. Cheap units with thin metal and cost-cut manifolds fail in 3 to 5 years and cost more in total over the same period.

Step 12: Maintenance Schedule

Daily. Wipe down burners, grates, and exterior with mild detergent. Avoid chloride-based cleaners on stainless steel (chloride pits the passive oxide layer). Empty drip trays at the end of every shift (accumulated grease is a fire hazard). Lift off cast iron grates and scrub off carbonized food residue with a stiff brush; heavy deposits insulate the grate, interfere with pan stability, and cause off-odors at next firing. Visually inspect each burner head for clogged ports, warped seating, or uneven flame carryover. Confirm pilot flames are steady, blue, and properly contacting the thermocouple. Test each knob for smooth valve travel and confirm it returns to the off position without binding. Remove boil-over debris immediately after cooldown so starches, salts, and grease do not bake onto the burner deck. Wipe down the oven interior.

Weekly. Pull grates and burner caps, soak in degreaser, scrub. Inspect burner ports for blockage and clean with a wire if needed. Re-season cast iron grates: dry thoroughly, apply a thin layer of food-grade oil, run a low flame underneath for 15 minutes. This restores the protective oxidation barrier and prevents rust. Inspect oven door gasket for cracks, brittleness, or compression loss.

Monthly. Pull burner pans, deep clean. Inspect manifold and gas connections for grease buildup. Test each burner valve for smooth operation. Clean hood filters.

Quarterly. Full degrease underneath the unit if on casters. Qualified technician verifies manifold gas pressure with a manometer (4 inches W.C. for NG, 10 inches W.C. for LP), calibrates oven thermostat against an oven thermometer (plus or minus 5 degrees Fahrenheit tolerance), and leak-checks all internal gas connections with soap solution or an electronic leak detector. A simple field leak check uses soapy water on every connection; bubbles indicate a leak.

Annually. Professional inspection and gas pressure verification. Replace any worn gaskets or valve stems. Check anti-tilt bracket attachment. Verify all safety controls are functioning.

Step 13: Troubleshooting Common Issues

Burner will not ignite. Verify main gas valve is open. Confirm the pilot is lit (standing pilot units). Clear burner ports of food debris with a wire or paperclip. Check the igniter or thermocouple on electronic ignition units.

Yellow lazy flame. Indicates orifice or venturi blockage, low manifold pressure, or wrong gas conversion (NG orifice on an LP supply or vice versa). Clean the orifice. If yellow persists, have a tech verify manifold pressure.

Flames lifting off the burner ports with a roaring sound. Opposite of yellow flame: manifold pressure is too high. Have a tech verify pressure against spec and adjust the regulator.

Standing pilot will not stay lit. Clogged pilot orifice or failing thermocouple. Clean the orifice; if pilot still goes out after staying lit briefly, replace the thermocouple.

Oven will not reach temperature. Manifold pressure issue, failed igniter or thermocouple, wrong orifice, or out-of-calibration thermostat. Verify manifold pressure first, then move down the diagnostic tree.

Oven temperature inconsistent. Door gasket failure (heat escaping), thermostat drift, or thermocouple wear. Replace gasket first (cheapest), then have tech calibrate thermostat.

Smell of gas. Natural gas is naturally odorless; the rotten-egg smell comes from mercaptan, an additive blended into the supply specifically so leaks are detectable. If you smell it, stop cooking immediately. Do not operate any electrical switches, turn on lights, or create sparks (any of these can ignite the leak). Turn off the main gas supply if you can reach it safely. Extinguish open flames. Ventilate the area. Evacuate the building and call the gas company from a safe distance. Do not return until cleared by the utility or fire department.

Frequently Asked Questions

What's the difference between a commercial gas range and a commercial gas stove? None. The terms are interchangeable. Manufacturers, spec sheets, and the industry use "range" more often; operators say "stove" in conversation. Same appliance.

What BTU per burner do I need for a busy restaurant? 28,000 to 32,000 BTU per burner for most independent restaurant cooklines. 35,000+ BTU for steakhouses, wok stations, and any operation searing high volumes of protein on demand.

How many burners for a 6-burner gas cooktop commercial setup? A 6-burner unit is the 36-inch configuration, the most common size on independent cooklines. Right-sized for full-service restaurants, diners, and bistros pushing 100 to 300 covers per service. The Atosa AGR-6B delivers approximately 219,000 BTU total.

Natural gas or liquid propane: which is better? Same heat output per BTU rating, same cooking performance. The choice is determined by your gas supply, not preference. If you have city natural gas service, choose NG (typically lower per-BTU cost, no tank management). If you don't, choose propane. Some operations prefer propane because it burns slightly hotter per unit volume; in commercial applications with regulators set to spec, the difference is negligible.

Can I convert a commercial gas range from NG to LP (or vice versa)? Yes, most commercial gas ranges including the Atosa AGR line accept conversion kits. The conversion swaps orifices and regulator settings. Must be performed by a qualified technician. Buying the correct fuel-type unit up front is simpler and avoids the conversion cost. See the propane conversion guide for details.

What's the difference between a 4-burner commercial stove and a residential 4-burner stove? Commercial 4-burner ranges use 28,000 to 32,000 BTU open burners, heavy-gauge stainless construction, cast iron grates, brass manifolds, and NSF/ETL certification. Residential ranges top out around 18,000 BTU and aren't built for 12+ hour daily service. A residential range in a commercial kitchen will fail within 1-2 years and may not pass code inspection.

Do I need a hood for a commercial gas range? Yes. Type I grease hood with fire suppression, sized to cover the unit plus 6 inches on each side. Non-negotiable for code compliance in every jurisdiction.

How long should a commercial gas range last? 10 to 15 years with proper maintenance and one parts replacement cycle (valves, gaskets, thermocouples). The chassis and manifold are durable; wear parts need scheduled attention.

Can I install a commercial gas range in a residential building? Almost never. Residential gas supply, ventilation, and code requirements aren't designed for commercial BTU output. Check with your local AHJ before assuming this is possible. Some jurisdictions allow it with upgraded gas line, Type I hood with fire suppression, and clearance from combustibles per the spec sheet, but most residential codes weren't written for 200,000+ BTU appliances.

What's a commercial cooktop versus a commercial gas range? Technically, a cooktop is just the burner surface (no oven), and a range is the full appliance (burners plus oven). In casual conversation buyers often use "cooktop" to mean the full range. Standalone commercial cooktops without an oven exist as countertop hot plate units (12-inch 2-burner Atosa ACHP-2 is the standard) or as drop-in countertop ranges.

Is a commercial gas range with griddle a single appliance? Yes. Combination ranges replace 2, 4, or 6 burners with a flat griddle plate in the same footprint. See the AGR-2B24GR, AGR-4B36GR, and AGR-6B24GR configurations on the ranges collection page.

Do commercial gas ranges include built-in temperature probes? Some higher-tier and specialty commercial gas ranges include integrated thermostat probes in the oven for precise temperature reading, eliminating the guesswork that comes from a dial alone. The Atosa AGR oven uses a calibrated thermostat (175-550 degrees Fahrenheit, plus or minus 5 degrees tolerance) rather than a probe; for probe-precision baking, pair the range with a separate convection or combi oven.

What about electric, induction, or dual fuel? Gas remains the standard for commercial cooklines because of immediate flame response, high BTU output, and reliability during power outages. Electric ranges (resistance heat) are slower to respond but cleaner. Induction ranges are 85-90 percent energy-efficient (vs about 40 percent for gas), run cool to the touch, but require ferromagnetic cookware and a 208/240V circuit at 40-50 amps. Dual fuel combines gas top with electric oven, preferred by bakers for the drier baking heat. The Atosa AGR line covers natural gas and propane only; electric and induction are separate product categories.

What kind of price range should I budget for a commercial gas range? Plan on $1,700 to $4,000 for a standard Atosa AGR commercial gas range depending on size. Combination ranges add $500 to $1,200. Specialty equipment (wok ranges, hot tops, stock pot ranges) and premium brands run higher.

What is millivolt vs electronic ignition? Millivolt is another term for standing pilot ignition. Uses a small continuous flame; works without electricity; simpler and cheaper to repair. Electronic ignition uses an electric spark; pilotless; more gas-efficient but requires electrical connection and won't work during a power outage. Most independent operators choose millivolt for reliability.
