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.
How many BTU is it?
33,000 BTU/hr total: 3 heavy cast iron burners rated at 11,000 BTU/hr each (3 x 11,000 = 33,000).
What gas connection does it need?
A 3/4" NPT connection at the right rear of the unit. Manifold 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?
The spec sheet lists 8" at the rear and 12" at the sides from combustible walls, and 0" from non-combustible walls. Royal's countertop manual calls for a non-combustible counter, so plan a non-combustible counter and wall where you can.
Does it need an electrical outlet?
No electrical connection is listed. It lights with standing pilots and runs on manual valves.
What options are available?
Fish grate; diamond grate; stainless steel splash guard tapered to front. Royal also makes matching stainless steel equipment stands with optional 5" swivel casters. Call us to add any of these.
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); cast iron parts are covered for 90 days. The spec sheet also lists a "fully welded frame with lifetime warranty"; Royal's warranty page does not detail that term, so ask us to confirm it with Royal.
How do I clean it?
Daily, clean the grates with warm water, a mild cleaner and a wire brush, brush debris from around the burners, and empty the crumb pan. Wipe stainless steel with hot soapy water; don't use steel wool or abrasive powders.
