When to Use a Commercial Stove in a Restaurant

"Do I really need a commercial stove?" is one of the most common questions a new restaurant operator asks, and the honest answer is: it depends on what you serve, how many covers you do, and where you cook. A residential stove will fail a health inspection in a fixed restaurant. A 60-inch eight-burner range is overkill for a 30-seat bar with a snack menu. The right answer sits between those extremes, and it is set by your menu, your cover count, and your operating model. This guide walks through the volume thresholds, the major use cases, and the specific Atosa AGR configurations that match each one.

Commercial Stove Versus Residential Stove: The 60-Second Version

If your operation serves the public for money, you need a commercial-rated stove. Residential ranges are listed under UL 858 or ANSI Z21.1 for household use only. A health inspector reads the rating plate at opening, and a household-listed range fails commercial inspection regardless of how well-built it looks. Commercial ranges carry NSF/ANSI 4 listing for foodservice and ANSI Z83.11 / CSA 1.8 for commercial gas appliances. They also burn at higher BTU (Atosa AGR open burners produce 32,000 BTU compared to 9,000 to 18,000 BTU on premium home ranges) and use heavier-gauge steel, heavier cast-iron grates, and commercial-rated valves and knobs. Full breakdown in the natural gas ranges guide.

Insurance liability is the other reason this matters. Most general liability and property insurance carriers require NSF-listed commercial equipment. A residential range installed in a foodservice space can give the carrier grounds to deny a fire or injury claim, even if the stove was not directly involved. The same logic shows up in most commercial leases: the operator is required to use only commercial-rated equipment. The savings from buying a residential range disappear the moment any claim is filed.

The rest of this guide assumes the stove is going into a commercial setting and the question is which commercial stove, not whether to skip commercial altogether.

The Volume Threshold: When You Outgrow a Small Range

Burner count and oven capacity scale with covers per service. A useful rough framework for full-service restaurants with a typical 60-minute table turn:

• 0 to 40 covers per service: 24-inch 4-burner range (Atosa AGR-4B) handles the cookline. One oven cavity. Two to three cooks max.
• 40 to 80 covers per service: 36-inch 6-burner range (Atosa AGR-6B) gives room for simultaneous sauce, sear, and stockpot work. One oven cavity holds full 18 by 26 inch sheet pans. Three to four cooks.
• 80 to 140 covers per service: 48-inch 8-burner range (Atosa AGR-8B) with dual oven cavities, or a 36-inch range plus a separate convection oven. Four to six cooks.
• 140-plus covers per service: 60-inch 10-burner range (Atosa AGR-10B) or paired ranges. Often a 36-inch range plus a 36-inch range with griddle, or a 48-inch range plus a 24-inch range with charbroiler. Six-plus cooks on the line.

The framework breaks down at the edges. A pizzeria doing 100 covers off a deck oven and one prep range needs less burner space than a sauté-driven Italian restaurant doing 60 covers. Use the framework as a starting point and adjust for menu structure.

Hood CFM and Clearance by Range Size

The hood and clearance requirements scale with the range. Two ranges of different sizes do not share the same install plan. Confirm the spec sheet for your specific model and check local code, but the typical numbers:

• 24-inch range (AGR-4B, ~152,000 BTU total): Hood 30 inches wide (6 inches overhang on each side), 600 to 800 CFM exhaust capacity. Type 1 hood, wet-chemical fire suppression.
• 36-inch range (AGR-6B, ~219,000 BTU total): Hood 42 inches wide, 900 to 1,200 CFM. Same Type 1 hood and suppression requirements scaled up.
• 48-inch range (AGR-8B, ~290,000 BTU total): Hood 54 inches wide, 1,200 to 1,500 CFM. Suppression nozzle layout matches the burner pattern.
• 60-inch range (AGR-10B, ~360,000 BTU total): Hood 66 inches wide, 1,500 to 1,800 CFM. Often paired with make-up air units sized to replace what the hood exhausts.

Clearance from walls: Commercial ranges require 6 inches of clearance from non-combustible walls (stainless, tile, gypsum with fire-rated panel) and 36 inches from combustible surfaces (wood, drywall without fire panel). Many restaurant build-outs handle this by installing stainless wall panels behind the range, which lets the range sit closer to the wall without violating code. Always confirm the clearance numbers on the spec sheet for the specific AGR model; the requirements vary slightly by burner configuration.

Use Case 1: Full-Service Restaurant

This is the baseline. A sit-down restaurant cooking to order from a menu of 12 to 30 items needs open burners for sauté, simmer for sauces and reductions, and oven cavity for finishing and roasting. The Atosa AGR series in 24, 36, 48, and 60 inch sizes covers the range from neighborhood bistro to mid-volume independent restaurant.

• Recommended starting point for most independent restaurants: AGR-6B 36-inch with 6 open burners and one full-size oven. Handles 50 to 90 covers per service comfortably.
• Two-cook small-format restaurants: AGR-4B 24-inch. Pairs well with a separate 24-inch convection oven or a 24-inch flat griddle on the line.
• Steakhouse, chophouse, sear-heavy menu: Skip the griddle combo, use the full open burner count for high-BTU sear and stockpot work. Add a separate charbroiler. See commercial charbroilers.

Use Case 2: Diner and Breakfast-Heavy Service

Diners cook on griddle for at least 60 percent of orders during breakfast service. Pancakes, eggs, bacon, hashbrowns, and sandwiches all live on the griddle. A range-griddle combo unit puts the griddle and the open burners on a single chassis with a shared oven cavity below.

• Atosa AGR-4B36G: 60-inch combo, 4 open burners plus a 36-inch griddle plate, shared full-size oven cavity. Built for the diner format where the griddle runs all day and the open burners handle eggs to order, sauces, and oatmeal.
• Atosa AGR-2B36G: 48-inch combo, 2 open burners plus a 36-inch griddle, full-size oven. Smaller diner format or breakfast-focused cafe.
• Standalone griddle as alternative: If you already own a 4- or 6-burner range and want to add griddle capacity, a separate 24- or 36-inch countertop griddle preserves your existing range investment. See the commercial griddle guide.

Use Case 3: Food Truck and Mobile Operation

Mobile cooklines almost always run on propane. Utility natural gas is not available on a truck. Truck cooking requires LP-rated equipment, smaller footprint, and equipment that can handle road vibration and limited generator power.

• Atosa AGR-4B-LP: 24-inch 4-burner LP range. Most common food truck range. Fits standard truck cookline configurations. Pairs with a 24-inch flat griddle or a 24-inch charbroiler depending on menu.
• Battery ignition consideration: Some propane ranges use D-cell battery spark ignition and require no electrical service. Useful when running off limited generator power or wanting to keep the genset off during prep. The AGR series uses standing pilots which also run without electricity but burn a small amount of LP continuously.
• LP tank sizing matters for trucks: A 100-pound tank can vaporize enough LP for one open burner and one griddle continuously, not for a 4-burner range running flat out. See propane stove tips for vaporization rate detail.
• Hood and fire suppression still required. Truck inspectors check for Type 1 hood and wet-chemical suppression identical to a fixed restaurant. Skipping these is the fastest way to fail a mobile food unit inspection.

Use Case 4: Catering and Commissary Operation

Catering operations batch-cook in volume. The cooking workload is closer to an institutional cookline than a restaurant, with large stockpots, sauce pans, and roasting trays moving through the line. Batch operations care more about pot capacity and burner output than about variety of burner sizes.

• Stockpot range as the workhorse: A 2-burner stockpot range puts two heavy-duty burners at low working height for 40-quart stockpots, brewing systems, or stocks. Pairs with a standard range for sauce work.
• 48 or 60-inch range for primary cooking: AGR-8B or AGR-10B handle simultaneous batches with room for the cook to work without stacking pans.
• Convection oven separate from range oven: Catering production frequently needs three to five sheet pans cooking at once. A standalone full-size convection oven removes the bottleneck of waiting for the range oven to free up.

Use Case 5: Ghost Kitchen and Cloud Kitchen

Ghost kitchens are delivery-only operations cooking from a commissary or shared cooking footprint. The cooking volume is high but the menu is narrow, often three to five items per brand. Footprint and ventilation matter more than variety of equipment.

• Compact range as the cookline anchor: AGR-4B 24-inch range handles the burner load for most ghost kitchen menus. Saves square feet for prep, packout, and pickup staging.
• Combine with one specialty appliance: Most ghost kitchen menus center on one cooking style (fryer-heavy for chicken brands, griddle-heavy for burger brands, char-heavy for grill brands). Pair the AGR-4B with the specialty unit instead of buying a 6 or 8-burner range you will not fully use.
• Shared commissary considerations: If you are cooking out of a shared commissary, your range is shared too. Bring your own pots, pans, and cleaning tools, and confirm the commissary's BTU and hood capacity matches your menu before signing the lease.

Use Case 6: Bar and Limited Food Menu

Bars that serve a limited food menu (wings, flatbreads, snack plates, hot pretzels, nachos) often do not need a full range. The cooking volume is too low to justify the footprint, and the menu structure favors fryer, panini press, or impinger oven over open-flame range work.

• If your menu is fry-only: Skip the range. A 40 or 50-pound fryer plus a small countertop range or hotplate for prep covers everything. See commercial deep fryer guide.
• If your menu is bake-only (flatbreads, pizza, pretzels): A countertop conveyor oven or a deck oven plus a single hotplate handles the cookline. No need for a 4-burner range.
• If your menu adds 2 to 4 cooked-to-order items: A 24-inch 4-burner range is the smallest practical commercial range. Below that, look at 12 or 24-inch countertop hotplates.

When You Should Not Buy a Full Range

A full commercial range is not the right buy for every operation. Skip the range if:

• Your menu has no cook-to-order items. Pre-packaged or prepped offsite menus need finishing equipment (impinger, panini press, microwave, conveyor oven), not range burners.
• Your covers per service are under 20. A coffee shop or pastry counter with a small lunch menu can usually handle the cookline on a 12 or 24-inch countertop hotplate plus a panini press or convection oven.
• Your menu is single-product specialized. Ice cream shops, juice bars, donut shops, smoothie shops, and similar single-product operations do not need open burner range work.
• You are converting an existing space with no gas service. Bringing utility gas to a building can cost $5,000 to $20,000 depending on trenching distance. If your menu can be served on electric or induction equipment, the gas-line cost may not be worth it.

For these cases, look at countertop hotplates, induction burners, panini presses, and conveyor ovens instead of a full range.

Matching Burner Count to Cooks on the Line

The other way to size the range is by labor structure. Each cook works approximately two to three burners simultaneously during peak service: a sauce pan, a sauté pan, and a stockpot or finishing pan. The math:

• 1 cook: 2 to 4 burners. AGR-2B (12-inch) or AGR-4B (24-inch).
• 2 cooks: 4 to 6 burners. AGR-4B (24-inch) or AGR-6B (36-inch).
• 3 cooks: 6 to 8 burners. AGR-6B (36-inch) or AGR-8B (48-inch).
• 4 cooks: 8 to 10 burners. AGR-8B (48-inch) or AGR-10B (60-inch).
• 5-plus cooks: 10-plus burners. AGR-10B (60-inch) or paired ranges with a charbroiler or griddle between cooks.

If your cover count says one size and your cook count says another, go with the larger. A range that is too small bottlenecks the line; a range that is one size too large adds a small amount to the gas bill and the hood requirement, nothing more.

Match the Stove to the Stage of the Business

The stove that fits a new restaurant on opening day is not always the stove that fits the same restaurant three years later. Common upgrade paths:

• Year 1 single AGR-4B grows into AGR-4B plus charbroiler or griddle. The original range stays, a secondary unit handles the menu expansion.
• Year 2 AGR-6B replaces AGR-4B as covers grow past 60 per service. The smaller unit becomes a backup or moves to a satellite location.
• Year 3 standalone convection oven added when the range oven becomes a bottleneck. A 1-deck convection oven costs less than upgrading from a 4-burner range to an 8-burner range.
• Year 5 second-location buildout uses the lessons from the first location. Often the second location has a larger range from day one because the operator now knows the cover count.

The point is to buy for where you are, not where you wish you were. Buying a 60-inch range to serve 30 covers wastes capital and floor space.

Stove Buying Mistakes Specific to Use Case

• Buying a residential range to save money on a fixed restaurant. Fails health inspection on day one. The warranty is void from the moment the range is installed in a commercial space. Repair calls are out of pocket. The savings are negative.
• Buying a range-griddle combo when you do not run breakfast. The griddle plate sits cold for most of service, taking up footprint that could be open burners. Combo units are for diners and breakfast-heavy menus, not for dinner-only operations.
• Buying a 60-inch range for a 30-cover restaurant. Overcapitalized on day one. The hood requirement goes up with the range size, which raises ventilation and fire suppression costs unnecessarily.
• Buying NG when the building has no NG service. A common mistake on new buildouts. Confirm utility service before placing the order. The LP variant of the same range is one part number away.
• Buying without confirming hood capacity. A 6-burner range needs a larger hood than a 4-burner range. Upgrading hoods after install costs more than upgrading the range itself.
• Buying a range that does not fit the door. Measure delivery path before ordering. A 60-inch range that arrives at a 32-inch back door is a return shipping bill.

Stove Stage by Restaurant Type: Quick Reference

Use this as a starting point. Your specific menu, cover count, and labor structure may push you up or down a tier.

• Cafe with hot sandwiches and soup: AGR-2B 12-inch or AGR-4B 24-inch.
• Neighborhood bistro, 40 to 70 covers: AGR-4B 24-inch or AGR-6B 36-inch.
• Diner, 80 to 150 covers, breakfast-heavy: AGR-4B36G 60-inch combo or AGR-2B36G 48-inch combo.
• Independent restaurant, 60 to 120 covers, dinner-focused: AGR-6B 36-inch or AGR-8B 48-inch.
• High-volume restaurant, 150-plus covers: AGR-10B 60-inch plus separate convection oven and charbroiler.
• Food truck: AGR-4B-LP 24-inch propane.
• Ghost kitchen, single concept: AGR-4B 24-inch plus the specialty appliance for the brand.
• Catering or commissary: AGR-8B 48-inch or AGR-10B 60-inch plus stockpot range plus convection oven.
• Bar with snack menu: Countertop hotplate plus fryer. Skip the full range.

Frequently Asked Questions About Restaurant Stoves

Can I use a home stove in a commercial setting if my volume is low? No. The rating plate determines whether the range passes commercial inspection, not the volume of cooking. A residential range listed under UL 858 fails commercial inspection regardless of how lightly it is used. The warranty is also void the moment the range is in a commercial space. Buy the smallest commercial range that fits your menu (the AGR-2B 12-inch is the entry point).

How many burners do I actually need? Plan on two to three burners per cook on the line at peak. A 2-cook line needs 4 to 6 burners (AGR-4B or AGR-6B). A 4-cook line needs 8 to 10 burners (AGR-8B or AGR-10B). Cover count is a useful cross-check but cook count drives the burner math.

Do I need a range or can I get by with countertop hotplates? If your menu has no oven-finishing items and your peak burner count is 2 or fewer, countertop hotplates work. The moment you need to roast, bake, or finish in an oven, you need a range or a separate oven. For most fixed restaurants, the range is the right answer because the oven cavity comes with the burners.

Is a range-griddle combo worth it? Only if you serve breakfast or a griddle-heavy menu (smashburgers, philly cheesesteaks, breakfast plates). A combo unit gives up two to four burners to add a griddle plate. If the griddle runs cold half the time, you bought the wrong unit.

Should a food truck use natural gas or propane? Propane. Mobile food units do not have access to utility natural gas. The LP version of the AGR series (AGR-4B-LP, AGR-6B-LP) ships factory-configured for propane.

What does NSF certification mean and why does it matter? NSF/ANSI 4 is the foodservice standard for commercial cooking equipment. It covers material safety (food-contact surfaces), cleanability, and durability under commercial use. Health departments check for NSF listing at opening. A non-NSF range fails inspection.

How long should a commercial stove last? A well-maintained Atosa AGR range lasts 10 to 15 years in a typical restaurant. The cast-iron grates and stainless body outlast most other components. Pilots, thermocouples, and gaskets are the wear parts that need replacement every 2 to 5 years.

Do I need a hood and fire suppression for a small range? Yes. Local code requires Type 1 hood and wet-chemical fire suppression over any commercial cookline regardless of range size. A 24-inch AGR-4B needs the same suppression coverage as a 60-inch AGR-10B; only the hood size scales.

Can I move from a 4-burner to a 6-burner range later? Yes, but the hood and gas supply have to support the larger unit. Upgrading from a 24-inch range to a 36-inch range often means upgrading the hood, the gas line, and the suppression nozzle layout. Plan ahead by buying a hood and gas line one size larger than your day-one range if you expect to grow.

What is the most common stove buying mistake? Buying for the restaurant you wish you had instead of the restaurant you have. A 60-inch range in a 30-cover restaurant wastes capital, floor space, and hood capacity. Match the range to the current cover count and upgrade later when volume justifies it.
