Description
Four wok and pot burners on two levels, with the rear row raised 4", for Asian kitchens that cook in woks and stock pots side by side.
The ORSU-424 is the 24" model in Royal's Delux Original Flex System step-up line: 4 cast iron burners at 30,000 BTU, each under a 3/8" plate with a 9-3/4" stainless steel wok ring or a 12" x 12" cast iron grate, mixed the way you need, with the rear row raised 4". The fully welded frame is listed with a lifetime warranty on Royal's sheet. It suits Chinese, Thai and other Asian restaurants that hold woks and stock pots on one countertop. Order it for natural gas or propane; the pressure regulator comes with the unit.

Delivery and setup
- Ships by freight carrier; the shipping cost depends on your location. See our shipping policy for details.
- Call (201) 467-8222 for the current lead time before you schedule installation.
- Choose natural gas or LP when you order. If your kitchen is above 2,000 feet, tell us the elevation so Royal can set the unit up for it.

- Inspect the shipment before signing and note any visible damage on the freight bill.
Questions buyers ask
Does it run on natural gas or propane?
Either. Pick Natural Gas or Liquid Propane (LP) before adding it to the cart; Royal builds it for the gas you specify. Tell us your elevation if you are above 2,000 feet.
Does it come with wok rings or grates?
Each section can have a 3/8" plate with a 9-3/4" stainless steel wok ring or a 12" x 12" cast iron grate. Royal's catalog lists extra grates, extra wok ring tops and swapping a grate for a wok ring as options, so tell us the mix you want when you order.
What gas connection does it need?
A 3/4" NPT connection at the right rear of the unit. Pressure is 5" W.C. for natural gas and 10" W.C. for propane, and the regulator ships with the unit for your installer to connect.
How much clearance does it need from the wall?
Royal's spec sheet lists 4" at the rear and 15" at the sides from combustible walls, and 0" from non-combustible walls.
How much higher are the rear burners?
The rear row is raised 4": Royal's drawing shows 10" at the front and 14" at the rear section.
What does it weigh?
Royal's 1-26 spec sheet lists 144 lbs. shipping weight and the 2026 catalog lists 154 lbs. Plan for 154 lbs. when you arrange the delivery.
What does the warranty cover?
Royal's limited warranty is 2 years on parts and 1 year on labor from installation (up to 30 months from manufacture); the spec sheet also lists a lifetime warranty on the welded frame. Cast iron parts, such as grates and burner heads, are covered for 90 days. Labor is covered when an authorized Royal service agency does the work.
How do I clean it?
Daily, clean the grates and wok rings with warm water, a mild cleaner and a wire brush, brush debris from around the burners and empty the crumb pan. Now and then remove the burners, clean them with a wire brush and check that the ports are open.
