36-Inch Commercial Gas Stove Buyer's Guide

A 36-inch commercial stove is the volume-selling restaurant range. Six open burners deliver 192,000 BTU of cooktop capacity (32,000 BTU per burner on the Atosa AGR-6B) plus a 27,000 BTU oven, for 219,000 BTU total connected load. The 36-inch width is the most common size on US cooklines because it covers the 100 to 300 cover-per-service range, fits a full-size sheet pan in the oven, and supports a three-cook brigade on the line. This guide covers when 36 inches is the right size, the AGR-6B in detail, sheet pan capacity, install requirements, and where the 6-burner falls short.

When a 36-Inch Commercial Stove is the Right Size

A 36-inch 6-burner range is the right call when the operation matches one of these patterns:

• Full-service restaurant running 100 to 300 covers per service. Six burners covers two to three cooks working in parallel during peak.
• Gastropub or bistro with a 20 to 40-item menu. The cooktop real estate handles saute, sauce, blanch, and finish work simultaneously.
• Brunch or breakfast operation doing high-volume egg work, hash browns, pancakes, and stovetop preparation. Six burners is the standard for a Sunday brunch service hitting 200+ covers.
• Catering kitchen doing batch production with multiple stockpots, sauce pans, and braising work running at the same time.
• Pizza shop with secondary cooking running pasta water, sauce, saute, and side dishes alongside the main pizza oven.
• Banquet kitchen needing cooktop capacity for plating sauces and finishing dishes for large-format service.
• Ghost kitchen or shared commissary where 6-burner is the standard rental commitment for higher-volume virtual brands.

The 6-burner is the wrong size when daily volume exceeds 300 covers (step up to the AGR-8B), when the kitchen needs dual oven temperature zones (8-burner has two ovens), or when floor space is under 36 inches (drop to the AGR-4B at 24 inches). See the complete guide to restaurant ranges for the full sizing framework.

36-Inch Commercial Stove Specs

Standard specifications for a 36-inch commercial gas range (Atosa AGR-6B as the reference unit):

• Width: 36 inches.
• Depth: 31 inches on the AGR-6B (36 W x 31 D exterior).
• Height: 57-3/8 inches overall on the AGR-6B (cooking surface roughly 30 inches; high backguard and over shelf bring total height to 57-3/8 inches per the factory spec sheet).
• Open burner count: 6, arranged in a 2x3 grid.
• BTU per burner: 32,000 BTU on the AGR-6B.
• Total cooktop BTU: 192,000 BTU.
• Oven interior: 26.5 inches wide, 26 inches deep, 14 inches tall on the AGR-6B (a full standard oven cavity sized to fit a 36-inch range).
• Oven burner BTU: 27,000 BTU.
• Total connected BTU: 219,000 BTU on the AGR-6B (192,000 cooktop plus 27,000 oven).
• Net weight: 440 lbs (gross shipping weight 568 lbs on the AGR-6B).
• Sheet pan capacity: One full-size sheet pan (18 inches by 26 inches) fits centered with proper airflow on each side. Two half-size sheet pans (13 by 18) fit side by side. This is the key advantage over the 4-burner: the 26.5-inch oven cavity accommodates production baking.
• Oven racks: 2 chrome-plated wire racks, adjustable to multiple positions.
• Thermostat range: 175 to 550 degrees Fahrenheit.
• Gas intake: 3/4 inch NPT rear gas connection, regulator provided.
• Electrical: None required. The AGR-6B uses standing pilot ignition for cooktop and oven; no 120V outlet, no control board.
• Cast iron grates: Heavy-duty 12 inch by 12 inch removable cast iron top grates (6 grates total on the 6-burner).
• Casters: Four casters standard from the factory.
• Stainless steel construction: Front, back, sides, kick plate, back guard, and over shelf in stainless on the AGR series.
• Oven interior finish: Enamel interior for easy cleaning.
• Certifications: cETLus (ETL 4003935), ETL-Sanitation (NSF/ANSI 4), ANSI Z83.11b-2009 (2011), and CSA 1.8b-2009 (2011).

The Atosa AGR-6B in Detail

The Atosa AGR-6B is the volume-selling 36-inch commercial gas range in the US independent restaurant market. Available in both natural gas and propane at the same price:

• AGR-6B Natural Gas
• AGR-6B Propane

Both ship with the conversion kit for the opposite fuel packed inside the oven cavity, so the range can be field-converted later by a licensed technician without buying new parts.

What the AGR-6B Does Well

• Full-size sheet pan oven at 26.5 inches wide. One 18x26 sheet pan fits centered with 4 inches of side clearance, leaving room for proper convection air flow. This is the practical baking threshold for commercial work.
• 32,000 BTU per burner across all six burners, no power burner / simmer burner asymmetry. Every spot on the cooktop delivers full output.
• Heavy cast iron grates sized at 12 by 12 inches and removable individually. A failed grate is replaced as a single part, not the entire cooktop assembly.
• Stainless steel construction on the front, sides, back, kick plate, back guard, and over shelf. No galvanized panels.
• Standing pilot ignition with no electrical hookup. Survives power outages, no control board to fail.
• Four casters standard for easy roll-out cleaning and service access. Most competing units charge for casters as an optional upgrade.
• Conversion kit included regardless of fuel type ordered.
• Parts availability through Atosa US distributors and restaurant equipment supply houses. Burner heads, thermostats, thermocouples, and orifices stock at most major distributors.

Where the AGR-6B Falls Short

• Single oven means single temperature zone. If the line needs simultaneous low-temp (proofing, holding) and high-temp (finishing, baking) work, a 6-burner with one oven cannot do both at once. Solution is either a separate combi or convection oven, or step up to the AGR-8B with dual ovens.
• Standing pilots burn gas continuously. Six pilots plus an oven pilot consume roughly 4,000 to 6,000 BTU per hour total, adding $250 to $500 per year to the gas bill. The trade is reliability vs. fuel cost; standing pilots win on a working line, electronic ignition wins on a low-volume operation.
• 440 lbs of net weight requires planning for delivery, install, and any future moves. A pallet jack and two people minimum for placement.
• No salamander or hot top option. The AGR-6B is six open burners period. Operations needing a salamander, charbroiler section, or hot top either choose a different model or run a separate piece of equipment.

36-Inch vs 24-Inch vs 48-Inch Sizing

Decide between the three Atosa AGR sizes using these heuristics:

• 24-inch (AGR-4B): Cafes, food trucks, ghost kitchens, second-line backup. Under 100 covers per service. Space-saver 20-inch oven cavity. See the 4-burner gas stove guide for details.
• 36-inch (AGR-6B): Full-service restaurants, gastropubs, catering. 100 to 300 covers per service. Full 26.5-inch oven cavity fits a single 18x26 sheet pan.
• 48-inch (AGR-8B): High-volume restaurants, banquet, large catering. 300+ covers per service. Dual 20-inch ovens for two temperature zones.

The price gap from 24-inch to 36-inch is roughly $300 to $500. From 36-inch to 48-inch, roughly $500 to $700. Most operators undersize when they should step up; the upgrade cost is small compared to running short of cooktop capacity at peak. Compare against the AGR-4B and the AGR-8B if you are on the line between sizes.

36-Inch Commercial Stove Install Requirements

Hood and Fire Suppression

• Type 1 hood sized to cover the range with 6-inch overhang on each side. A 36-inch range needs a 48-inch hood minimum.
• Exhaust CFM sized by NFPA 96 and local mechanical code. For a 6-burner range at 219,000 BTU connected load, exhaust is typically 350 to 500 CFM depending on hood type and overhang.
• Wet-chemical fire suppression integrated into the hood with nozzles aimed at the cooking surface. Fusible link activation at typically 360 degrees Fahrenheit.
• Makeup air sized to match exhaust volume. Insufficient makeup air creates negative pressure problems on adjacent equipment.

Gas Supply

• Natural gas: 3/4 inch building supply line sized for the total connected BTU including other gas equipment on the same line. A 6-burner range alone at 219,000 BTU is typically fine on 3/4 inch; check the line if it feeds additional equipment.
• Propane: Two 100-pound tanks minimum on a fixed install, or a 250-pound tank as a single source. Mobile installs use the standard food truck two-tank setup.
• Use 3/4 inch gas hose, not 1/2 inch. A 1/2 inch hose restricts flow and prevents the 32,000 BTU burners from hitting full output, even with correct manifold pressure at the regulator. Six burners running simultaneously starve on an undersized hose.
• Yellow PTFE pipe sealant only on gas connections. White PTFE is rated for water and degrades on gas service.
• Manifold pressure: 5 inches water column for NG, 10 inches water column for LP, verified with a manometer at commissioning.
• Quick-disconnect plus restraint cable at the range location.

Floor and Clearances

• Sealed concrete or quarry tile floor rated for commercial kitchen use.
• Clearance to combustibles: 6 inches to both sides, the back, and the bottom on a non-combustible floor per the Atosa AGR installation manual. 36 inches to combustible surfaces unless wall protection is installed.
• Aisle clearance: 36 inches minimum behind the range for service access. 42 inches preferred so the range can be pulled fully forward for cleaning behind.

36-Inch Commercial Stove Operating Cost

Annual fuel cost for an AGR-6B at typical operation:

• Light-duty (bistro, dinner-only, 6 hours per day, 25 percent average duty cycle): 200 MMBTU per year. At natural gas $11 per MMBTU, $2,200 per year. At propane $26 per MMBTU, $5,200 per year.
• Medium-duty (full-service restaurant, 10 hours per day, 35 percent duty cycle): 280 MMBTU per year. NG $3,080 per year. LP $7,280 per year.
• Heavy-duty (high-volume catering or banquet, 14 hours per day, 45 percent duty cycle): 500 MMBTU per year. NG $5,500 per year. LP $13,000 per year.

Operating cost favors NG at any duty cycle. LP is the right answer only when NG is unavailable. See the natural gas guide for the full NG economics or the propane guide for the LP details.

36-Inch Maintenance Schedule

• Daily: Remove all 6 grates and burner caps for cleaning. Wipe burner heads. Clear food debris from burner ports with a small wire. Empty and clean the drip tray. Wipe cooktop, control panel, and oven door.
• Weekly: Remove all 6 burner heads for soak cleaning. Check air shutter setting on each burner (steady blue with sharp inner cone). Wipe oven interior. Check oven door gasket.
• Monthly: Pull the range forward and clean behind it. Check the flex hose for kinks or damage. Verify the restraint cable is intact. Check all 6 pilots for steady ignition.
• Annual: Licensed technician inspection. Manometer check at the manifold test port. Thermocouple inspection on all pilots. Oven thermostat calibration (within plus or minus 15 degrees of dial setting). Hood and fire suppression inspection on the same visit.

For the full procedure, see commercial gas range tips.

36-Inch Stove Common Failures and Fixes

• One or more burners will not light: Clogged port (clear with wire), clogged orifice (remove and clean), or pilot too low. Holding the safety valve button for 10 to 15 seconds while igniting fixes most relight situations after a pilot has gone out.
• Yellow or orange flame on one burner: Air shutter closed too far on that specific burner, partially clogged orifice, or grease buildup in the burner head. Always troubleshoot one burner at a time; air shutter settings are individual.
• Yellow flame on all burners: Manifold pressure too low (regulator check with manometer), incorrect orifice for fuel type (verify NG vs LP), or building gas line undersized for total load.
• Flame lifting off the burner ports: Air shutter open too far, or manifold pressure too high (regulator failure).
• Oven not reaching set temperature: Thermostat calibration, thermocouple failure, or oven door gasket damage.
• Pilot will not stay lit: Thermocouple failure (replace), clogged pilot orifice, or draft from venting issues.
• Gas smell: Treat as a leak. Shut off the supply valve, ventilate, evacuate, and call the gas company emergency line.

36-Inch Commercial Stove Buying Checklist

Before signing the purchase order on a 36-inch commercial gas range, verify:

• BTU per burner 30,000 BTU minimum, ideally 32,000 BTU. Anything under 25,000 BTU compromises performance.
• Fuel type matches the site. Order the correct factory configuration.
• NSF/ANSI 4 listing for commercial foodservice.
• ETL or UL listing for commercial gas appliance safety.
• ANSI Z83.11b-2009 (2011) compliance.
• Stainless steel construction on the front, sides, back, kick plate, back guard, and over shelf.
• Cast iron grates rather than thin steel wire grates.
• Standing pilot vs electronic ignition decision. Standing pilot is simpler and more durable; electronic saves gas but adds repair complexity.
• Oven interior dimensions 26 inches or wider for full-size sheet pan baking.
• Casters included rather than upcharged. The AGR-6B includes four casters standard.
• Restraint cable hardware included or ordered separately. Required by most install codes.
• Conversion kit included in the oven cavity (Atosa AGR series ships this by default).
• Warranty terms: Atosa AGR-6B ships with a 1-year parts and labor warranty (US only) per the factory spec sheet.
• Propane orifices (if converting): The AGR-6B oven uses an LP54 orifice for propane. Top burners on the AGR series use LP54 propane orifices for the 32,000 BTU spec. See the propane conversion guide for the full procedure.

36-Inch Stove in a Combination Layout

Atosa also offers the AGR-4B36G combination model: a 60-inch range with 4 burners on one side and a 36-inch built-in griddle plate on the other, all sharing two ovens. This combination layout is the right choice when the line needs simultaneous burner work and dedicated griddle space (breakfast operations, diners, burger operations). The AGR-4B36G specs:

• Width: 60 inches (4 burners + 36-inch griddle on the same chassis).
• Cooktop BTU: 128,000 BTU (4 burners) plus 75,000 BTU (griddle) = 203,000 BTU cooktop.
• Oven BTU: 54,000 BTU total across two ovens.
• Net weight: 792 lbs.
• Same standing pilot, no electrical, four casters standard configuration as the AGR-6B.

The AGR-4B36G is the wrong tool when the operation needs maximum cooktop flexibility (six burners beats four burners plus a griddle for menus that change). The combination unit is the right tool when the menu locks in significant griddle work.

Frequently Asked Questions

How wide is a 36-inch commercial stove? 36 inches wide on the Atosa AGR-6B and most standard 6-burner commercial ranges. The 36-inch width is the volume-selling size on US cooklines because it covers most full-service restaurants up to 300 covers per service.

How many BTU is a 36-inch commercial stove? The Atosa AGR-6B delivers 32,000 BTU per burner across 6 burners (192,000 BTU cooktop) plus a 27,000 BTU oven for 219,000 BTU total connected load. Lower-cost imports often run 22,000 to 26,000 BTU per burner; verify spec sheets before purchase.

Can a 36-inch commercial stove fit a full-size sheet pan? Yes. The AGR-6B oven cavity is 26.5 inches wide, accommodating a single 18x26 full-size sheet pan with 4 inches of side clearance for proper convection. This is the practical baking threshold and the key advantage over the 24-inch AGR-4B.

How heavy is a 36-inch commercial stove? The AGR-6B has a net weight of 440 lbs (gross shipping weight 568 lbs). Plan for delivery with a pallet jack and a two-person crew minimum for placement.

Does a 36-inch commercial range need 240V electrical? No. The AGR-6B is purely gas-operated with standing pilot ignition for both the cooktop and the oven. No 120V outlet, no control board, no electrical hookup required. This is one less failure point on the unit.

What hood size do I need for a 36-inch commercial stove? A 48-inch Type 1 hood minimum, with 6-inch overhang on each side beyond the range. Local mechanical code may require a larger hood depending on building specifics. Exhaust CFM typically 350 to 500 for a 219,000 BTU connected load.

How much does a 36-inch commercial gas stove cost? Atosa AGR-6B typically $1,800 to $2,400 depending on dealer and current pricing. Lower-cost imports at $1,200 to $1,500 deliver weaker burner BTU, galvanized side panels, and lighter construction. Premium ranges at $4,000+ add features like simmer plates or hot tops.

Is a 36-inch commercial stove worth the upgrade from a 24-inch? Yes for any restaurant doing over 100 covers per service, any operation that bakes full-size sheet pans, or any line with three or more cooks working in parallel. The $300 to $500 price gap is recovered quickly in throughput.

What is the warranty on the Atosa AGR-6B? 1-year parts and labor warranty (US only) per the factory spec sheet. Verify warranty registration at delivery.

How long does a 36-inch commercial gas stove last? 10 to 15 years with maintenance. Thermostats and thermocouples need replacement every 3 to 5 years. Door gaskets every 18 to 36 months. Cast iron grates last the life of the range. The Atosa AGR series is built for a 15-year service life.

What is the best 36-inch commercial gas stove? The Atosa AGR-6B is the volume seller in the independent restaurant market because it combines a strong commercial spec (32,000 BTU per burner across 6 burners, 26.5-inch oven for full sheet pans, stainless construction, four casters standard, no electrical hookup, included conversion kit) with parts availability and a 1-year parts-and-labor warranty at a working price point. See the AGR-6B-NG or AGR-6B-LP for details.
