Commercial Wok Range Buying Guide: BTU, Ring Size, Gas Type and Clearances

Search "wok burner" and most of what comes back is a three-legged propane stand for a driveway crawfish boil. A commercial wok range is a different machine: a stainless cabinet on legs, plumbed to a gas line, with a jet burner sized to flood the whole curved underside of the wok. This guide covers the three numbers that actually decide which one you buy — BTU, ring size and gas type — and the clearances people discover too late.

1. Wok range, wok burner, wok stove

In a commercial kitchen the three words mean the same equipment: a gas-fired cabinet with a recessed ring that holds a round-bottom wok over a high-output burner. "Mandarin range" and "Chinese range" are the same thing again.

What they do not mean is the portable propane burner sold for outdoor cooking. The difference is not marketing:

• It is plumbed, not bottled. A commercial wok range connects to your building's gas supply through a fixed inlet at a set height. It is not designed to sit on a 20 lb tank.
• It is certified for commercial use. ETL and NSF listings are what your health inspector and your insurer are looking for. An outdoor burner carries neither.
• It is built to run all service. Stainless body, cast iron top, welded frame, adjustable legs — rated for continuous use rather than an afternoon.
• The burner geometry is different. A jet burner fires a ring of flame tips upward and inward around the wok's curve, so the heat wraps the bowl instead of hitting one flat spot underneath. That wrap is what a flat open burner on a standard commercial gas range cannot reproduce, no matter how high you turn it.

2. BTU and the burner tip count

BTU per hour is the headline number, but on a wok range it is downstream of something more useful: how many flame tips the jet burner has. More tips means the ring of fire is denser and reaches further up the wok's sides.

Both of ours use stepless flame control rather than fixed settings, so the same burner drops down for simmering sauces and braises. The jump from 95,000 to 125,000 BTU is worth paying for when you are cooking bigger batches per toss, not simply more of them — a busier kitchen with the same portion size is usually better served by a second station than by a hotter one.

3. Ring size decides the wok

Our wok ranges are 17 1/2" wide either way — the cabinet does not grow with the burner. What changes is the ring:

• 13" ring — takes a standard restaurant wok. The everyday size for single-portion and two-portion stir-fry.
• 16" ring — takes a large wok for family-size portions, batch prep and catering pans.

Buy the ring that fits the wok your kitchen already cooks with. A wok noticeably smaller than its ring sits too low and the flame licks up past the rim; one too large perches on the edge and rocks while you toss. Measure the wok you have across the top rim before choosing.

4. The models, side by side

Four units, two burners, two gas types. Everything except height, weight and inlet position is shared:

All four: stainless steel body, cast iron cooking surface, stepless flame control, removable drip tray, 14 2/5" adjustable legs, ETL and NSF listed, 1-year warranty.

5. Propane or natural gas

Order the version that matches the gas at your address — natural gas if the building is on a utility line, liquid propane if you run off tanks, which is the usual case for food trucks, rural sites and temporary kitchens.

6. Install: height, hood, clearance

• Check the gas inlet height against your stub-out. It sits at 19 3/5" on the 95,000 BTU units and 18" on the 125,000 BTU units. If your existing connection is at a fixed height, this is the measurement that decides whether the install is an afternoon or a plumbing change.
• 34" to 35 1/5" tall on 14 2/5" legs — the legs adjust, so the wok top can be levelled with the rest of the cook line rather than standing proud of it.
• It must sit under a Type I hood. Wok cooking is the greasiest, smokiest thing most kitchens do; this is grease-laden vapor, not steam, and it is not a step you can defer.
• Leave the front clear. Cooking at a wok range is a whole-body motion — you need room to pull the wok off the ring and toss without hitting anything behind you.
• Plan the water. Most wok stations sit next to a swing faucet for rinsing between dishes. Decide where it goes before the range is bolted in place.
• 77 to 84 lb — light enough for two people to place, heavy enough that you want the floor and the gas connection sorted first.

7. Before you order

• Measure your wok across the top rim — that picks the 13" or the 16" ring.
• Confirm your gas type, and order LP or NG to match rather than planning to convert.
• Check gas line capacity and hood rating against 95,000 or 125,000 BTU per hour before committing to the larger burner.
• Measure your gas stub-out height against 19 3/5" or 18".
• Confirm the hood is Type I and covers the footprint with the required overhang.
• Have a licensed gas fitter do the connection — and any conversion.
