IMPORTANT. Installing, Operating and Service Personnel:

Qualified, certified, licensed and/or authorized personnel who are familiar with and experienced in state/local installation
codes should perform installation of the equipment. Qualified or authorized personnel who have read this manual and are familiar
with the functions of the equipment should perform operation of the equipment.

Qualified personnel who are knowledgeable with Royal equipment should perform Service of the equipment.

INSTALLATION INSTRUCTIONS

Gas pressure regulator provided with the equipment must be installed when the appliance is connected to gas supply. The
area around the appliance must be kept free and clear of combustibles such as solvents, cleaning liquid, broom, rags, etc. Proper
clearances must be provided at the front of the appliance for servicing and proper operation.
Provisions shall be incorporated in the design of the kitchen, to ensure adequate supply of fresh air and adequate clearance
for air openings into the combustion chamber, for proper combustion, and ventilation. For proper operation of the appliance, do
not obstruct the flow of combustion and ventilation air.
The installation must conform with local codes, or in the absence of local codes, to the national fuel gas code, ANSI Z223.1
(or latest addenda). The Appliance and its individual shut off valve must be disconnected from the gas supply piping system during
any pressure testing of that system in excess of ½ PSI (3.45Kpa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shut off valve during
any pressure testing of the gas supply piping system at test pressures equal to or less than ½ PSI (3.45Kpa).
The gas supply line must be at least the same size as the gas inlet of the appliance.

If legs or casters are not used, the unit must extend 2” beyond the front edge of a noncombustible curb or platform.

Broilers are for installation in non-combustible locations only.

FLEXIBLE COUPLINGS, CONNECTORS AND CASTERS

For an appliance equipped with casters the installation shall be made with a connector that complies with the Standard for
Connectors for Movable Gas Appliances, ANSI Z21.69 or Connectors for Moveable Gas Appliances, CAN/CGA-6.16, and a quick
–disconnect device that complies with the standard for Quick Disconnect Devices for Use with Gas Fuel, ANSI Z21.41, or Quick
Disconnect Devices for Use with Gas Fuel, CANI-6.9. Adequate means must be provided to limit the movement of the appliance
without depending on the connector and the quick-disconnect device or its associated piping to limit the appliance movement.
Restraining devices may be attached to the back frame/panel of the unit.

WARNING Improper installation, adjustment, alteration,
service or maintenance can cause property damage, injury
or death. Read the installation, operating and maintenance
instructions thoroughly before installing or servicing this

HIGH SHELF ASSEMBLY

(1) Mount the backguard/ flue riser to the range with #10 sheet metal screws (12 total) in the back.
(2) Mount the high shelf to the riser with ¼-20 x 1/2 bolts provided (see attachment at the end of this manual for a

diagram that describes the installation of the backguard / flue riser).

NOTE: If a Salamander broiler / Cheesemelter is to be mounted on range, read installation instructions for Salamander broiler /
Cheesemelter before installing high shelf. Special care must be taken to ensure that the gas supply piping and/or gas pressure
regulator is not exposed to exhaust gases, or elevated temperatures.
The gas supply (service) line must be the same size or greater than the inlet line of the appliance. Royal ranges and ovens
use a 3/4” NPT inlet. Sealant on all pipe joints must be resistive to LP gas.

ELECTRICAL CONNECTION

CONVECTION OVEN requires a 120 volt supply to operate the ignition system and blower. The supply cord provided along
with the appliance is equipped with a three prong (grounding) plug for protection against shock hazard. The electrical service in the
building must be equipped with a properly grounded three prong receptacle, in accordance with local codes, or in the absence of local
codes, with the national electrical code, ANSI/NFPA 70-1987, in Canada, conform to Canadian electrical codes, CSA-C22.1. Do not

cut or remove the grounding prong from this plug. Wiring diagram is located on the backside of the appliance. Disconnect power
supply before cleaning or servicing. NOTE: This appliance is not capable of being operated in the event of power failure. No attempt

should be made to operate this appliance during power failure.

OPERATING INSTRUCTIONS: Before lighting, check all joints in the gas supply line for leaks. DO NOT USE OPEN FLAME
TO CHECK FOR LEAKS! USE SOAP AND WATER SOLUTION.

Putting an open flame beside a new gas connection is extremely dangerous.

LIGHTING Initial pilot lighting:

CAUTION When lighting pilots and checking for leaks, do not Stand with your face close to the combustion chamber.

All Royal Range appliances are adjusted and tested before leaving the factory, effectively matching them to sea level
conditions. Adjustments and calibrations to assure proper operation may be necessary on installation to meet local conditions, low
gas characteristics, to correct possible problems caused by rough handling or vibration during shipment, and are to be performed
only by qualified service personnel. These adjustments are the responsibility of the customer and/or dealer and are not covered by
our warranty. Before lighting any pilots, make sure that burner valves and thermostats are turned “off”.

A. TOP BURNERS / RAISED GRIDDLE–BROILER / BROILER. All top section burners are equipped with constant­burning pilots. These are to be manually lighted immediately after the gas is turned on and the system is checked for leaks. Burner
pilots are provided for each burner and can be rechecked for proper adjustment. Adjustments can be made with a screwdriver to
the brass pilot valve accessible through the valve cover.

B. HOT TOP / GRIDDLE. The pilot should be lighted immediately after the gas is turned on and the system is checked for
leaks. The pilot can be reached with a long match through the valve cover, or by lifting the plate upward and accessing through
the top.

C. STANDARD OVEN. Pilot gas is tapped from the main burner manifold pipe, routed through tubing to a pilot safety valve,
and then to the pilot burner. Gas flow is controlled by the safety valve.
Oven pilot lighting or relighting is to be completed in the following sequence:

(1) Turn the oven thermostat knob to “off” and wait 5 minutes.
(2) Remove the oven’s lower kick plate by lifting up and out. This exposes the pilot safety valve and the igniter button.
(3) Make sure any accumulated gas has dispersed. Since propane gas is heavier than air, check near the floor area for the

odor of propane gas before attempting to light any pilot burners.

(4) Depress the red button on the safety valve and hold it in throughout the lighting procedure.
(5) Press the red button of the pilot igniter, and you should hear a snap and see a spark at the pilot burner. If a spark or spark

igniter is not present apply a lit match to the pilot burner head.

(6) Continue to depress the safety valve button until the pilot remains lit when released.
(7) If pilot is extinguished, repeat step 4 through 6 above.
(8) Turn the oven thermostat knob “on” and set to desired temperature setting, watch to make sure the oven burner ignites

from the pilot and that there are no yellow flames from the burner.

(9) Turn the oven thermostat to “off” and replace the lower kick plate.

NOTE: It may be necessary to relight the pilot several times until the lines are purged of any trapped air and a constant gas flow
is attained.
