WHERE THIS CUISINE QUIETLY COSTS YOU MONEY

Chinese / Wok-specific conversion gotchas

  • 01 · Wok-range BTU load

    A single 16" wok burner runs 100,000–150,000 BTU; a four-burner Chinese range commonly hits 600,000+ BTU. The hood, exhaust fan, and gas service in the previous tenant's set-up almost certainly weren't sized for that. Confirm hood CFM, exhaust duct size, and gas-meter capacity BEFORE signing.

  • 02 · Make-up air sizing

    For every CFM the hood exhausts, you need a matching CFM coming in — typically 80–85% of exhaust as a dedicated tempered MUA unit. A 4,000 CFM wok hood with no MUA pulls negative pressure through the front door, slams it, and chases customers out. MUA is often an extra $8K–$15K conversion line item.

  • 03 · Stainless wall behind the wok

    Code (and insurance) require non-combustible wall + ceiling surfaces within ~36" of any wok burner. Drywall behind the previous tenant's pizza oven won't pass — budget for stainless sheet or fire-rated tile across the whole back wall.

  • 04 · Wok-water drainage

    Wok stations use a constant cool-water spray to keep the ring temperature down — that water has to go somewhere. Most wok ranges ship with a built-in 2" floor drain requirement. If the existing slab doesn't have a drain in the right spot, you're saw-cutting concrete (~$3K–$8K + permit).

  • 05 · Grease load + interceptor sizing

    Wok cooking generates 2–3× the grease load of grill or sauté. The previous tenant's grease interceptor was probably sized for that operation, not a wok line. Many AHJs require resizing under IPC Section 1003 — expect a 1,000+ gallon interceptor + a pump-out frequency increase from quarterly to monthly.

Five immediate stop signals

These cancel any deal regardless of cuisine.

  • You smell gas, see burnt wiring, or see blackened / charred hood areas.

  • The exhaust fan is missing, disconnected, or shaking violently.

  • The seller refuses to provide hood / fire / grease records.

  • You must add major cooking equipment outside the existing hood.

  • The landlord will not allow roof, gas, electrical, or grease-interceptor work.

Defined terms in this guide

The vocabulary worth knowing before you sign.

BTU (British Thermal Unit)· BTU
The unit of energy a gas-fired cooking appliance consumes per hour. A standard residential burner is ~12,000 BTU; a commercial wok burner is 100,000–150,000 BTU per ring.
CFM (Cubic Feet per Minute)· CFM
The volumetric flow rate of an exhaust hood or make-up air unit. A typical commercial pizza hood pulls 1,500–2,500 CFM; a high-BTU wok hood can pull 4,000+ CFM.
Make-Up Air· MUA
Conditioned outside air drawn into the kitchen to replace what the hood exhausts. Sized at 80–85% of exhaust CFM as a tempered, dedicated unit.
Type I Hood
A grease-rated commercial exhaust hood with stainless construction, filter banks, and fire-suppression integration. Required over all grease-producing appliances per NFPA 96.
Grease Interceptor
An in-ground or in-line tank that separates fats, oils, and grease (FOG) from kitchen wastewater before it enters the sewer. Sized per IPC §1003 fixture-unit math.
