Description
A 24" infrared griddle with a solid state thermostat every 12", for kitchens that need even, held plate temperatures on a short line.
The RD100-24 heats a 1" thick polished steel plate with two 20,000 BTU infrared burners, each run by its own solid state thermostat set anywhere from 150°F to 450°F. The 24" deep cooking surface suits diners, breakfast lines and burger stations that cook to a set temperature all day. It has pilot safety with electronic ignition, so it plugs into a standard 120V outlet as well as the gas line.

Solid state thermostats
A thermostat every 12" with a sensor embedded in the plate, adjustable from 150°F to 450°F, with a burner "on" light for each zone.
1" thick plate
A 1" thick steel plate with a polished cooking surface and a 24" deep cooking area, the same depth front to back on every RD100 width.
Safety and cleanup
Pilot safety with electronic ignition, a large stainless steel grease can, and a fully welded frame with stainless steel front and sides on 4" adjustable legs.
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.
- A qualified installer must connect it following local codes, with the supplied pressure regulator and a manual shut-off valve ahead of the unit, and plug it into a grounded 120V receptacle.
- 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 need electricity?
Yes. The thermostats and electronic ignition need 120V, 60Hz, 1 phase power at 1 amp, through a 6' cord with a standard 3-prong grounded plug. Royal's manual says not to operate it during a power failure.
How does the temperature control work?
Each 12" section has its own solid state thermostat with a sensor embedded in the plate, adjustable from 150°F to 450°F. The 24" model has two independent zones.
What gas connection does it need?
A 3/4" NPT connection at the right rear. Manifold pressure is 5" W.C. for natural gas and 10" W.C. for propane; the regulator ships with the unit for your installer to connect.
How much clearance does it need?
6" at the rear and 4" at the sides from combustible walls, and 0" from non-combustible walls.
What options are available?
Royal offers a grooved griddle section, a chrome griddle plate, a cutting board, a plate shelf and stainless steel equipment stands with optional 5" casters. Call us to add one.
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), with labor done by an authorized Royal service agency. Royal lists the welded frame with a lifetime warranty.
How do I clean the griddle plate?
Daily, scrub the warm plate with warm water and a fine-grit griddle brick, and empty the grease can. Wipe stainless steel with hot soapy water; don't use steel wool or abrasive powders.
